I put together a 12' aluminum enclosed trailer for my repair business, I put white steel panels on the roof and painted the walls and floor a light gray, and put two strips of these Hitlights, 4000k high density 828 lumens per foot lights inside, in 10mm wide aluminum channel with lightly frosted lens covers, and it's absolutely perfect inside. Very bright, not at all harsh, and basically looks like daylight inside with no shadows where I'm working. The only thing I had to change, was that due to the amp draw, I noticed the end 10' away from my connectors were noticeable dimmer than the beginning. To solve this, I simply fed a parallel feed to the far edge of the LED strip, spliced in at the lead edge and fed another connector at the far end. It cured the problem perfectly, and made the whole strip a bit brighter as well, since it wasn't restricting power through the very small wires of the strip. This would likely not be an issue on the lower lumen, lower wattage strips.
I'm going to purchase Hitlights 3000k lower output strips for the undercabinet lighting in my kitchen basement theater, I couldn't be more pleased with the quality and honest lumen output of these lights! I've tried other overseas brands, and their lumen ratings are usually about 200% percent optimistic in my opinion, however I won't bother anymore, I'll simply head straight to whatever fits the bill from Hitlights!
