LED Flood Light Replacements For Outdoor Motion Lights – I Use These


I believe that one of the best LED flood light replacements for outdoor motion lights is the Hyperikon® 1240 lumens flood light bulb.

Hyperikon® LED Flood Light
LED floodlight for outdoor motion light

Why? Because I have been using them in all of my outdoor motion lights for quite some time. No issues! Even in our weather extremes!

A number of years ago I replaced all of the standard tungsten incandescent flood lights / spotlights with these – for security around the home. They have been fully operational ever since.

I recently purchased and installed several more of these LED flood light bulbs for my ‘RAB Stealth’ outdoor motion lights (reviewed here).

They drastically reduce energy consumption! This is especially important to me because I’m running off-grid solar power. But that’s not the only reason…

These LED floods are currently the best replacement that I’ve found.
And here’s why…

Until these were developed, I had been using the typical 150 watt (tungsten) flood light or spotlight combination. When all of these lights were on at once (I have a number of motion lights), they were consuming many hundreds of watts. Since I now have solar panels (and a battery bank for nighttime energy) I am very conscious of energy consumption and these LED replacement bulbs have solved my problem…


Energy Savings in Watts

The Hyperikon® LED flood light will save approximately 85% electricity consumption based on ‘lumens’ equivalent (brightness), and only consumes about 10% of what a typical incandescent flood light uses. That’s a 90% savings differential!

Typical Flood light: 150 Watts
Hyperikon® LED flood light: 14 Watts

This is not only good news for general energy consumption, but if you have solar then it’s very significant! But there are more reasons why they’re the best:


LED Brightness Comparison

Brightness is expressed by a technical term called ‘lumens’.


A ‘typical’ 150 watt incandescent flood light puts out about 1700 lumens.

The LED replacement flood light that I’m comparing in this article puts out 1240 lumens (about 73% equivalent). HOWEVER, I’ve got to tell you that I really hardly notice any difference while comparing this LED to the regular flood light. This may be due to factors such as the beam angle, reflector design, and/or color temperature.

Beam Angle

This particular LED replacement bulb has a beam angle of 40 degrees (even though they call it a ‘flood light’). The light certainly is ‘pushed’ out there via the reflector design. Additionally, there is a good amount of surrounding light versus the ‘directed’ light – making for a very good ‘flooded’ mix in my opinion.



Color Temperature

This refers to how the cast of the light appears to your eyes – in gradients from warm to cool (reddish/yellow to blue/white).

Hyperikon® makes this LED bulb in three different color temperatures:

Daylight White (4000K)
Soft White Glow (3000K)
Warm Glow (2700K)

I have purchased the 4000K and the 3000K for my outdoor motion lights. The 3000K LED bulbs color temperature is nearly identical to a traditional flood light with its tungsten filament. It’s not ‘white’ or ‘blue’, but it has a yellowish hue.

LED Flood Light – Life Expectancy

This is a statistic where the LED really shines. The life expectancy is tremendously longer than a traditional incandescent bulb!

Typical 150 Watt Incandescent Flood Light: 1.8 years
Hyperikon® LED Flood Light: 21 years (45,000 hours)

So while the LED bulb costs more initially, it more than pays for itself due to its energy savings combined with life expectancy.


Additional Attributes Making It The Best…

DIMMING capabilities with a CFL/LED digital dimmer (which will also dim incandescent).

Unique color rendering technology, providing CRI90+ and R9>50. It’s ‘technical’, but to sum it up this means that the bulb is very good at reproducing ‘reds’ – which has been a difficult thing in LED technology. Perhaps this is the reason why I think it looks so good…

ENERGY STAR qualified

UL-Listed [E472253]



If you’re looking for a LED replacement flood light for your outdoor motion lights, you might consider the Hyperikon® PAR38 LED Flood Light Bulb, which I believe to be one of the best at this time…

  1. Thanks Ken. We have been replacing our old 300 watt halogen flood lights as they need replacing. The problem is that we have to replace the whole unit, not just the bulb. So it is a slow process.

  2. I don’t know if this could happen to floodlights, but I had an incandescent 150 watt bulb inside my garage heat up so fast that it exploded in the 20 degree Fahrenheit temperature. I’ve also had the spaghetti bulbs fail to do more than just glow in the cold.

    1. It’s typical for many of the ‘CFL’ (spaghetti) bulbs to brighten up slowly, and/or to perform poorly in the cold.

      On the contrary, the LED bulbs that I have experienced (so far) are instant-on and they’re performing well in the cold. I will find out more soon because we’re forecast to sink to 10 below zero Monday night… Not only will it be a good test for the outdoor motion lights I’ve described above, but the dog probably won’t be too happy around potty time… ;)

      1. It has been between -5 and 10 degrees here at night for the last week. All of our LED outdoor fixtures are intant on and working great! We replaced every bulb in and out of the house this year with LED’s and our electric bill has gone down as well!

        1. PW, We are in process of converting steel bldg,(no windows) into a home, which LED’s have you found to give a prolnged bright light/reading and other activities?

      2. Ken, I bought the CFL “flood light” bulbs to replace the older flood light bulbs. I wasn’t too impressed with their performance. They were expensive too. I will definitely buy some of these. LED lights are the way to go.
        I bought a few of the new Rayovac 6 volt lanterns that are LED. The batteries last a lot longer than the old style lights do.

        1. Agreed. I also tried the CFL floods, and I was not impressed. Additionally, for security lights you want the bulbs to come on full-bright immediately, whereas lots of the CFL’s start relatively dim and then brighten up. The LED’s blow them away…

  3. Ken,

    Appreciate the post, and when we get around to replacing our hard wired ones, am going to go this route. I like that they have LED bulbs, too.

    Happy New Year, and the best to you, the Mrs., and the four legged family too.

  4. Ken: Is it my understanding from this article that you must replace the lamp fixture to utilize the new LED bulbs, or can you just screw in a LED bulb in your old fixture?

    1. @Willy, Regarding the LED floodlights shown above, you simply screw in the replacement. It’s the same base. (direct replacement into your old fixture)

  5. I don’t know if it is still ongoing but last year Maine had (has) an energy program that significantly reduced the cost of LED light bulbs. We replaced every bulb in our house.

  6. LED replacement, as in Ken’s case, makes sense for off-grid homesteads, but be aware that LED’s usage which results in lower power consumption is not going without notice by Utilities. In our local the Utilities gave away curly tubes so there was less electrical demand, which they countered with higher electrical rates. As LED usage increases, don’t expect your rates to necessarily decline, they might in fact increase, especially with the installation of Smart Metering.

    1. TS
      On Smart Meters depending on where you live you have the right to refuse the installation of said product. Since my dh has a medical condition and the neighbor did, they were not allowed to put them on our boxes.
      The electric company is like a the car sales pitches you see on TV, it is not all they profess. Check your state, local requirements….PUC.

      1. If I remember correctly we were given the “option” to keep the old meter, if we were willing to pay an additional amount each month. I think it was something like 30 dollars “to pay for the manual reading of the meter.” No medical exemption as far as I know.

        It is interesting to me that since they put the “smart” meter in our power bills have gone up considerably, more than making up the difference the additional payment would have cost. Not the cost of power, but the amount of power being used has skyrocketed. Supposedly.

    2. @Thox
      You are spot on. I used to write articles about saving money and less use on electric power for my local power newsletter and they refused to publish them. However, they promoted and sold energy sucking appliances and an article about them used by a buyer was published that used twice as much power as I did with same square footage, based on my articles.

      This was after people used less power due to the 2008 crash, then they suddenly doubled our service fee from $21 to $42 a month, not including power. The power companies are out to make as much money as possible to use up their pre-bought allotment. They have not promoted LED lights but still sell the twirly-gigs. They are not interested in customers using less energy, they are only wanting to sell it.

      I have LED bulbs in my lanterns and surprised the 2 AA batteries haven’t gone dead using them around the house, forgetting to turn one off in my bedroom many times in two years since I had it. LED is the way to go!

  7. I have purchased two 120 V LED bulbs over a period of 8 years or so. Both of them stopped working within a month. They were not the bulbs in your article. Considering the cost if the LED light fails to give you 10 years of service you would be better off buying a incandescent. I assume others have had better luck than me with their LEDs But until the prices come down a lot I won’t gamble with them.

    1. Plus the technology has improved greatly over the years… Even this past year I have seen lots of additional availability and choices, but it’s still pricey…

  8. Appreciate the information on the bulbs. I would enjoy hearing from folks about what fixtures they are using and how they like them. I’m not having a lot of luck with the ones I’ve been getting at the local big box store.

    We were recently probed. I came out and noted that the cover on the rear of my F350’s fuel fill had been opened. Locking cap was intact but they did come up to my motion sensor light and turn the switch timer down to the lowest setting. Lesson being to mount these higher up. This was limited by where the original light had been mounted. I do have a floodlight on a timer mounted higher up on the garage which is currently not working. Tomorrow’s project will be to figure out why.

    As an aside on Christmas morning we had a brownout. Voltage just dropped and things quit working. Fridge made weird clicking noises until I turned off the breaker. When the power came back the computer was down.

    I had to go to LA the next day and didn’t get a new modem until I got back. Turned out the power supply went bad on it so I don’t know if the modem was effected or not as they had already given me a new one. Anyway the experience sure had me thinking about Ted Koppels book! I’m very glad it wasn’t an attack.

  9. Ken is using RAB products which are among the very best. If you have had bad luck with an LED product it was probably not made by RAB, Satco, etc.

    It also might help to understand that an LED lamp (light bulb) is an electronic device, basically comprised of two parts, the diodes and the driver. The diodes emit light and the driver is a small circuit board, usually located near the screw base of the lamp, that regulates power to the diodes. When the driver fails, the entire lamp (light bulb) fails. If individual LEDs within the lamp fail, the light output will become diminished. Either scenario is not what we expect from pricey LED lamps.

    As Ken said, the technology is improving rapidly but you should still carefully read the label and understand the properties of the lamp before making your purchase in order to avoid premature failures. Some lamps are not suitable for outside use (sometimes stated only if they are). Some are not dimmable (when it is dimable, it will be stated but may not be stated if it is not). Most need adequate ventilation and are not designed to be used in an enclosed light fixture (generally stated either way).

  10. Great post, great site. thanks for these tips, the only person putting out what I feel is honest legitimate information. going to purchase these asap.

    1. Thanks… I have had these LED lamps installed for some time now – and they’ve been operating perfectly. Not long ago we had a stretch of really cold weather (down to 20 below) and they worked perfectly. And the RAB Stealth outdoor motion light is still the best in my opinion. Been using them for years.

  11. So, if the RAB motion security light is the best, why aren’t they offered with the Hyperikon LED’s? This way they can be the best of the best.

  12. @David,

    “Your RAB lights have not only a motion but a photoelectric sensor as well so the lights will not be on in daylight and the LED replacements work with this feature?”

    I have a number of these RAB outdoor motion lights installed around the perimeter – all with the Hyperikon LED flood lamps (1200 lumen) (I personally like the 3000K color temperature – close to the original incandescent floods). The photoelectric sensor is doing its job properly by keeping these lamps off during daylight hours. I couldn’t be happier with the combination… Hope this helps.

  13. Hi;
    do you have a led spotlight that can be used outdoors with out hood/covers?
    our old type just screw in and are exposed to water etc.
    they are 100 watt units i’d love to replace.
    they have a motion detector but no daylight sensor .

  14. These days, numerous varieties of outoor security lightings are available.

    The main purpose of residential outdoor lighting is to provide a means to nip crime at the bud. You see, criminals and intruders usually put their evil plans into action on places that are dark or poorly lit. When they are in a well lit area, criminals feel apprehensive and exposed, making them find another place to strike.

    According to some, outdoor security lighting is a fairly easy and low-cost technique to curb burglars, trespassers, and vandals. Thus, it’ll surely save your home and property from great damage.

    Thanks for sharing this informative post with us.

    Very nice read!!

  15. I just spoke with RAB and they said LED light bulbs are not compatible with these fixtures. Thoughts?

    1. @Elsa, That is entirely incorrect.

      I use LED bulbs with ALL of my RAB ‘Stealth’ motion lights. I use the Hyperikon LED flood lights that are linked at the beginning of this article, and they have been in service for a long time. They have functioned through all of our four seasons of harsh weather, including 20 to 30 below zero temperatures, rain storms, snow storms, 90 degree+ summer temps, etc., and they work great!

      RAB sells MANY products, and perhaps they were referring to something other than the RAB Stealth motion light when you spoke…

      Additionally, you will notice as you scroll down the Amazon page to ‘Frequently Bought Together’, that others are buying this LED spotlight with the RAB motion light too…

  16. Great article, thank you! Quick question – I am interested in the RAB Lighting STL360HBW Super Stealth 360 Sensor with HB101 Bullet – do you think that the Hyperikon® BR40 LED Bulb, 15W (100W equivalent), 1420lm would work? I know that the PAR38 fits, seems the BR40 is similar and is 1 watt stronger (1420 lm), also offers 120 degree flood. I am thinking they may be too large?

  17. Got burned by the Defiant; hope this is better. Will I need the “round mounting box” or will it mount directly to the soffet.

  18. First of all, I don’t know what kind of flood light bulbs you were running, but 150 watt bulb putting out 1700 lumens is terrible! I have 90 watt floods that put out 1400 lumens each! Also, if that bulb puts out 1240 lumens for 14 watts as you claim, they have made giant leaps in LED technology in the last week!!! I follow LED technology very close and I can tell you your figures are WAY off! The savings claims are false also! LED will only save in the neighborhood of 70 to 75% not the 90% you claim!

    1. Well Phil, I might suggest that you try one of these LED floods. They’re pretty darn good. They’ve been running here for several years now without issue. Nice and bright. Manufacturer specs 1240 lumens. If you don’t agree with that specification then you might take it up with them. The cost savings is astounding over that of incandescent or halogen type bulbs. Heck, even if I saved 75% I would still be happy!

    2. Phil and Ken

      Not wanting to get in the middle of a Watt War, but I found a GREAT way to save 99.99%.
      Turn the lights off.

      Phil; the Manufacture of each Bulb is very easily found by a search on the Net.
      I have also done some look-see and yes some of the 150 watt-ers are only about 1680-1700 Limens.
      Plus I just installed new lights on me 50′ flag pole that are 20 Watt and hitting right at 1150 lumens….. Hope they last awhile, the lights are mounted at 45′ up, they light up the sky for sure.

      Just my 2¢ worth.

  19. Consistent with the comment above by Elsa McFly, I was advised by RAB that their “regular” stealth sensors should not be used with LED bulbs. LED bulbs can (and will) damage the sensor over time. RAB now makes a line of stealth sensors that are compatible with LED. As explained to me, LED bulbs have a higher initial surge of energy that takes a toll on the sensor.

    1. @Mitch, I can attest 100% that the LED bulbs that I have been using in my RAB sensors have not caused one single problem. Period. They’ve been great! And they have been running for years! I have lots of them around the house and property and no issues whatsoever. I wonder how much of what they may be saying is to market a new product (which I have no doubt will also be excellent, given their quality and performance reputation).

      The RAB motion light along with the Hyperikon LED floods are excellent…
