I found a clamp on goose neck Ikea lamp for $1.99 that I thought would be good to use in conjunction with a turntable - sort of a spot light.
It uses one of those Cree LED or something visually similar.
No AC power adapter was with it but I thought I could cross that bridge with a little research. It took fair bit of searching using various terms before I found something, a blog actually, whereby someone wished to change the LED inside one of these things because they did not like the color of the light it emitted. It clashed against the color of their other LED room lighting don't cha know. In any case the power source was identified as being 4v.
With that information I searched some thrift stores I know which have many, many AC adapters but found none with a 4v output. Most were 5 volts and higher. Thinking of this more of an experiment, I purchased one rated at 3v thinking that the LED would likely illuminate but at a reduced intensity.
This afternoon i identified which terminal of the lamp's plug was + and likewise the wire from the adapter.
So far so good but when I measured the voltage coming out of the adapter, it was 5v not 3v. Is this one of those instances when that voltage will drop once connected to a load or am I going to burn up the LED?
FWIW, while cruising the 2nd hand stores, I also looked for similar lamps and did find a few but they were all also without adapters. I also tried one of the area's Ikea stores. No adapters for this series of lamps were available, the lamp in question is discontinued and there were no such adapters or whole lamps in their "as is" department. They guy I asked did a pretty thorough look 'round.
