It used a CFL and I noticed static or some kind of interference in the reception. It could be lessened by changing the frequency a little, but the result was still less volume than when the light was off. So I figured, LEDs! They won't make interference. Bought Ecosmart. Then the radio hummed so loud I couldn't hear the station at all. I will probably go back to incandescent. Any other way to get rid of the hum? The noise you are hearing is the high frequency ac it generates. You don't have to do leds that way, its easy to have a constant current linear supply. How easy it is to find something in the specs on ebay or amazon tho is harder to say but they do exist. You've gotten too technical for me. Maybe people in the group I added can tell me where to buy what you're suggesting. |
