They say that imitation is the sincerest form of flattery.

I guess I should be flattered!

Put an AM radio in close proximity to the lamp. If they are using a switching regulator, you'll know it. The regulator is used to keep the intensity constant with variations in input voltage. Raz

Well...great minds think alike!

I didn't search the forum before posting so it's gratifying to see we both used the same basic approach. Your comparison is more comprehensive though. Good job!

Nice job on the comparison chart and getting all the measurements. It comes pretty close to what I would expect. I have the warm white LEDs 1156. Plenty of light and long battery life.

I was looking at various offerings on eBay, and am a bit confused as to the output of the lamps. Some list specs for wattage or amperage, some list lumens of output, but none that list lux. Is there some kind of conversion for comparison. It does seem that most of the LED's used for what I would want are 5050 or 2010 bulbs, how do these compare for output.

I would likely want mostly warm white ones, but it would seem for the same number of lights as the cool white, there is about 25% less light. Is this correct?

I want bright, but then I imagine everyone does.

"Lumen" is the thing that seems to be the standard for LED's. And, yes, the warm white ones have a lower lumen output. Personally, I really like the warm white colour. The "regular" white is a bit hard on my eyes...too much blue.

Agreed, lumens is used more often because it relates to total light output better than lux (which is more of a directional, one-spot measurement).

I think our little trailers are small enough that a lower light output (even 1/3 or 1/2 less than incandescent) emitter still produces plenty of light to see by. I find two places where I want more light: over the stove and over my book. So I left the incan bulb in over the stove, and I added a couple of directional LED reading lights in the places where I sit or recline.

Keep in mind, also, that you can turn on 6 or 8 LEDs in your trailer and probably draw less current than you would with one incan bulb. So in the rare instances when you want more light, you can easily get it.

What Mike said is very true. Under my kitchen counters at home I have one long strip of LED's. The light is absolutely shadowless.
