LEDs & Conventional Fluoros on same circuit?
HI Folks.
I've previously sung the praises of lightrabbit.co.uk / .ie for their GU10 Led lamps, which have proved to me much more reliable than the 'cheapie' eBay bulbs in our shop lighting. In my stained-glass lamps, I've been using CFL's - which work well. Recently, I thought I'd try some of lightrabbit's B22 LED candle-bulbs. All looked good in the workshop - two stained-glass lamps with B22 Leds fitted..... ....until I turned off the 2ft fluorescent work-light - which was running off the same 4-way extension lead - at which point both led bulbs emitted a 'pop' and failed. I contacted lightrabbit - and got this reply "The reason that these lamps have failed is because they were powered by an extension which was shared with fluorescent lighting. These would have caused a spike in the current which would have damaged the drivers withing the LED's causing them to fail. I recommend not using CFLs on the same circuit as LEDs." While I understand the physics behind it (inductive spike from the fluoro choke and all that) - wouldn't you expect that the designers of the led bulbs would add suitable filtering to their bulbs to prevent them just blowing like that? Any thoughts? Thanks Adrian |
