I have this LED clip on lamp that I got at Lowe's. I had one already that put out a nice white light so I have it clipped above my headboard for reading. Even though the first has 3 bulbs out I figured I'd buy another one to clip to the edge of my work table for additional lighting. Same packaging but purchased about 6 months apart. Only this one has 2 distinct issues 1) it has different color light...it's more of the yellowish color. Pulled both apart and they seemed to be manufactured identically. Guess the bulb batch was different? Not that major of an issue, but 2) is major! After about 1-2 min of warm up time it begins to shut off for about a second then comes back on. It does this pretty much nonstop and in no discernible pattern. The power supply says it's 10.5v but when I meter it where the power supply wires are crimped to the PCB wiring I get about 9.9v. Get ~2.85v across each of the LED's. Unfortunately the switch is snapped together and disassembling it may destroy it. Same with the power supply. Sound like a heat or a voltage issue? So here's a thought I have...the supply does say 10.5v @ .xA (can't rem what the current was right now & I'm at work). My bench power supply is currently an old 200w ATX PC power supply but I can't rem the amperage on the 12v rail off the top of my head. If it's near the lamp's power supply amperage can I hook the lamp directly to it? Maybe I should just take it back, swap it for a different one and hope for the best?
Guess I'm just curious about LED function and what I can do with it. Might as well take this opportunity to learn something! Any info/advice from you would be much appreciated.
Oh, one other issue that comes to mind after reading a few of the lower reviews at the Lowe's site; flicker! My eyes are fairly sensitive to 60hz flicker. Old school CRT's nearly kill me! I noticed this with the first lamp but it's only an issue if I am looking at it. It's not noticeable when reading under it. Just another issue with it that I wonder about fixing or if I'm stuck with the seizure inducing flicker?
