whats the best way to solve bulbs blowing?
Question by Robert J: whats the best way to solve bulbs blowing? i use halogen gu10 bulbs on our 230v mains circuit, it is not a practical option to replace the bulb type, i have tried using both Halogen and led bulbs and they have blown in short order in the same fitting (within a couple of months) i am aware the main cause of bulbs blowing is the heating and cooling of the filament, my house has its original wiring from the sixties, is it likely that the bulbs are victims of surges from the grid? if thats the case are there any inline surge protectors that can be wired in for the purpose or can you use an ac capacitor to smooth the current flow? and would i be correct in guessing it would be wired in parallel with the bulbs?

I want to change some of the bulbs to low energy led bulbs, but keep three of them as standard GU10′s Can I do this safely without the risk of overloading any of the bulbs in the circuit?

Which of these bulbs consumes the most electricity?
Question by : Which of these bulbs consumes the most electricity? I’m in the UK if it matters. I need to know which bulb out of these 4 takes the least electricity in order of least consumption first: - 12 volt bathroom style GU10 halogen with transformer - GU10 halogen - Normal incadescent bulb - LED
Assume all are kept on for the same duration and output 50W each. What would be the order of least power consumption first? By LED I mean a 50W output LED in GU10 form.

Question by jancee55: do led bulbs lose their brightness over a period of 4 weeks i.e gu10 repalcement for halogen? I purchased led gu10s (72 led) which weer very bright to start with but after only 4 weeks and not constant use they have started to lose their brightness. Has anyone any idea why? Other led gu10s (48 led) are as bright as when I got them. Not constantly left on or anything.
