Anyone know the watt draw of interior LED lights?
My fixtures have two boards with 48 LEDs each in them. Trying to get an idea of how much each fixture draws.

Yeah, but measuring lumens will be tricky ;)
It appears that Chinese manufacturers make those lumens numbers as they go. Here is 48 board from the Ebay store that sells a lot of LED lights. Naturally, a lot of people here have bought it there - which doesn't mean anything, it can't be no better than the next guy, he just sells a lot. 48 LED, 240 lumens. Check his "other items" and you will see 24-board with 350 lumens. Yes, sir - 1.5 times more light with 2 times less LEDs. Same warm white color. One of these lumens numbers is wrong, and God knows which one.
18 watt regular bulb from Camping World has rating 264 lumens, 1.4A. So the closest equivalent in brightness (i.e. lumens) is 24-board... or 48-board. I tend to think that 350 lumens for 24-board is a bullsh-t, and the closest equivalent to 18W bulb is 48-board. So 48-board should not draw more than 1/3 of 1.4A, or 0.45A (because average quality LED is 3 times more efficient than regular bulb). If it draws more, than you've got a lemon.
