I bought some LED bulbs from ebay a year ago, installed 4 of them into IP65 downlighter each with their own transformer in the bathroom but removed them because they often flickers or some just didnt light up. Any idea why this is? **** bulbs or just need better transformers? 4W LED Bulbs 4 10 12 X High Power GU10 MR16 Light Day Warm White Spot Lamp Ultra [Day White,MR16,4]
***** lamps is my first guess, I gave up trying to fit these ting-tong Chinese fittings they are mass producing and flogging on EBay One seller has stopped me from buying owing to negative feedback for his products Other option ****** is operating below its rating for the weakling 4W load Out of every 10 I fitted, 20% would fail JCC LED 7's all the way for me to keep business credibility!
Are you using 12V transformers or DC LED drivers? The transformers stress the first stage of the electronic drive.
