Has anyone used these in higher powered LED lights? I have a Nitecore EC25 (860 lumens) and was wondering if these can handle the current draw.

I don't see why it wouldn't work...i've cycled these batteries through 10+ cycles after draining them and they are still holding a charge..

I use them in a Fenix PD35 850 lumen light, and in a Nitecore EC25. No problems here.

5 amps tends to work best. If you go with a lower power they will not be as bright and technically it can handle more but it will shorten the life of the LEDs.

I find it hard to believe the cr123s would limit the high end output of the Xenix of any other light. In fact I was under the impression the 18650s were more limited on max lumens but provided a better burn time than the cr123s. My Nitecores and my fenix both seem to do very well on these cr123 cells...

The min/max wattage comment (by Scott) is spot on. My fixture had 3 dimmable LEDs and I had flickering. I swapped out one LED bulb for an incandescent to get above the min wattage. All flickering is gone. dimming works as expected.

they are rated 7-16v ac/dc. i can tell you they worked for a short while on 12vdc, when i tested them, but when i used 15v ac mocking up the fixture, 2 fried about the 3rd time switching on. i have one working on 12vdc regulated about 5 months they have a beefy bridge rectifier internally, but it seems the ic regulator or driver is not up to the task of switched supply that comes from an unbuffered 60hz rectified feed. they would have been better off using a more traditional regulator to drive the leds

Any standard size LED sold these days is probably going to have a max current of around 30mA. Run it at 80% of that for a good long life. Look online for data sheets to really get a handle on this.

I tried to use one of these on my 50 Watt LED flood light and it was strobing/pulsing. From what I hear these motion sensors need a certain amount of current (amp draw) to work properly. Which isn't a problem if you're using a halogen/incandescent or even compact fluorescent bulb. But since the LED lights use so little current it just strobes. If anyone knows how to get these to work well with an LED flood light I would love to know. Thanks

I purchased 10 3-packs for my home about 6-months ago. The majority of mine are located in enclosed fixtures. 6 have already failed. Finding LEDs that truly work in enclosed fixtures at the brightness you want, and the color you want can be quite challenging! I have other brands/models in my house as well, but none with a failure rate close to these.

These are SMD LEDs, which are designed for 12.0V-DC. The will, however operate on as little as 9V, up to a maximum of 18V before damaging them. They are DC ONLY! Running on AC current will damage them permanently. Also, 16.4' utilizes roughly 24W of power, and requires 2A output minimum on the power supply. If you are running these from the RV battery bank or the alternator, you will have more than ample power to supply several of these strips nightly. I am running six strips of these lights, one of them 24x7 from a bank of two 100Ah deep-cycle batteries, and the draw per day is only 12% of my total off-charge capacity daily. One strip can be ran for 4-days or more, without recharge! In an average RV setting, 4-6 hours per night, two batteries will supply the several strips for a week without need for recharge.

I haven't seen anything regarding this but I would not hesitate to use them in an enclosed fixture. If memory serves they only draw about 1/2 watt so any heat buildup should be minimal.

I have them running off a 12 VDC battery in a vehicle, which is around 13.8 volts DC. If you use a 12 volt DC power supply it will work. MAke sure the output current of the power supply is sufficient to power to lights. IN other words, do not use a very small plug-in 12VDC power supply. Use one that is at least the size of a normal men's wallet. If you use too small of a power supply it could overheat the power supply. THese lights work fantastic. Theyve been on my vehicle for over a year now and continue to work flawlessly.

They should be fine below 30W. I use mine in an SVD V2 up to 20W with no issues.

I am using them as back up lights. There are 5 1.5w plasma LEDs there is an heat sink on the case. They should be fine in continuous use. I have seen them in H3 fog-light form. I would get two sets if you need a pair. Sometimes one of the elements will flicker. I would get 4 keep the best 2 and return the second set. They are all made in china and the quality is inconsistent. This gives off the best 360 light and runs cooler than all the others I have tried.....DO-NOT use the 5w cree's in continuous operation.

Not sure of your power draw. I replaced all my bulbs to led and have one line 36 fixutes and no loss of brightness.

I have an electrical engineering degree but have changed career years ago. Unfortunately, technological knowledge has slipped. However, I gave some thought concerning any potential issue if I were to use a low voltage transformer (AC of course) to power these lights. I suppose powering them with with an AC transformer may cause more degradation and shorten the life of the bulbs but other than that, I could not come up with any reason on why they won't work. So, I bought eight to put into my two lamp posts and they seem to work fine with the transformer as a power source. I'm not sure if running the lights with a DC source would produce more lumens but with my transformer, four bulbs in one lamp post still seem dark, definitely not the claimed 75W equivalent (someone already claimed that he measured the power consumed to be less than 5W instead of 9W). However, for my purpose with the lamp posts being decorative, the lumens produced seem adequate as I do have other light sources, if needed. Concerning your question of will they last, I don't expect the degradation to cut the life of the bulb by half but have no data to back up my claim.

Yes. No problem. I installed the CREE 75 watt equivalent warm light bulb and they're awesome. And since my lights are on dusk-to-dawn, the lower LED power use really is an advantage.

No, these lights are NOT 300 lumens, even when using a 14500 battery. It's only about 80 lumens when using a AA or rechargeable NiMH. It's about double that with the 14500 lithium. The LED's in these lights are a few years old. They don't have the power to produce too much light.
