What is their power rating? Will they support 50W (over 4 amps at 12v) flowing through them for hours or burn/melt in a matter of days?

I use a 12 volt 50W Halogen with no problems. But it has never stayed on for longer han 12 hours at a time

The current rating is what matters as you can use these at 115V as well as 12V. My application was 360W at 83V so I was running around 4.3Amps. We had no failures in multiple days (probably 20 hours worth or operation). This socket was being heated by the bulb in my application much higher that what you are planning so probably it will take 50W at 12V with no problem.

I checked the box that my lights came in and it says 1.9A @ 12v, 0.8A @ 24v. It seems like when I installed them I checked the current draw and it was about 1.0A but can't remember for sure. However, using 27 watts and 12 volts it calculates out to 2.25 amps. I know mine are not drawing near that much.

I know they run on 12volts dc and I read back through some of the comments from others that have purchased and it has a 4amp draw. Hope that helps.

I don't know how many watts they are, but they heat up as fast and as hot as the factory seat Warner's in my 2012 Lexus. They draw less than 10 amps each (which is the manufacturers fuse size). Assuming a reasonable margin, I'd guess no more than 5-7 amps. They work great and were easy to install.

I have mine working on a landscape lighting transformer with output rate 12V AC, and they work fine. After several months, I've had none fail.

You would need a rather large amount of amps to reach that temperature. I would recommend getting these from a different source for the temperature you want. These may be cheap but they aren't very good quality.

These are listed as 6 ohm. That's a compromise between 4 and 8 ohms. These should be OK with either 4 or 8 as long as you aren't pumping maximum power thru them. Keep it under 100 watts and you probably won't notice any difference.

I looked for this information in the specifications but wasn't able to find any detailed parameters. However, I did expose several (~20) of these modules to a temperature gradient of 172 degrees celcius and they continued to work fine. (I used these to generate a current using 100 degree boiling water and a -72 degree ethanol dry ice bath)

I'm running these off of a 100W rms Pioneer amp and they handle it with no problem. They sound amazing with some power put to them. Hope this answers your question.

You are asking questions of other buyers as if we were the manufacture. I don't have any technical specifications but I would say that they aren't very bright at all, I wanted to use them in a turn signal application --- No way you could see these in bright sunlight, I didn't return them, but I bought two other solutions, one is a 5 meter strip, waterproof and much brighter and then I ordered two other strips that I hope are much brighter. As far as current draw I have a 30 AMP supply with a digital Amp Meter on it that can show down to 0.10 AMPS. These didn't even register on the Amp Meter. There isn't such thing as an Optimal Current Draw for LEDs. It totally depends on the type of led and how many are in the strip --- They draw what they draw at the rated voltage, A bright LED may draw 10X the current a dim LED draws. I would say that for a strip this length to be bright at all, it would have to use LED chips that when in an approximately 12" strip it should draw about 0.25 Amps at 12Volts.

I believe they use a 55 watt bulb, so at 12 volts, that's a bit under 5 amps. I use 2 of them on a 10amp fused circuit, hasn't blown yet.

They dont run hot but the filament breaks when lite falls on floor. they are to fragile. in my line of work i always carry a spare. never had one on long enough to judge the life. i would go led over this type.

Hey Donald this is Mark, I have used these bulbs now for seven months with no burn outs. I think they are rated for 12v to 24v. They use about 3 watts. Good Luck Mark.

These are 12VDC and draw about 0.25A at full brightness. A 30W transformer should be sufficient.

I would not use them on 400 V DC. My thought is it would get very hot and melt.

My experience was not good using them on 500W par 64 cans, they melted within minutes, so 100 W - if they are far away from the light they MAY be OK but I would not guarantee it. My smaller cans with 75W get pretty hot and warp the more expensive gels because the bulbs are about 1 inch away, so these would likely melt too. The PAR 64 cans held the gels about 10 inches away and as I noted they melted in minutes. These would work well for LED or fluorescent lights, but incandescent lights were a no-go for me.

Honestly I do not know....these are LED which are rated for gazillion hours so I am not concerned with them burning out ;-)
