Review on JACKYLED 20Pcs Screw Non Shunted Holder by Marcus Rash

For making 4 inch LED lights using a 1000 filament bypass ballast. It was easy to connect the wires to the lamp sockets and attach them to a piece of white fiberboard. With these lamps only requiring 120v for one end of the lamp (a 1x2 piece with holes to hold the other end) you could get 10-10,000 Kelvin for about $10 each (lampholders, bulbs and wood). Great value for the lamp holders and they work great.
