High Bay Lighting

[mayfair]

Hi Customer of mine has about 24 high bay metal halide light fittings 400w metal halide lamps........Dont seem to have much of a life 4-5 months and then they start flikering or after an hour go off them cool off and start again, Any ideas guys.
btw the lamps were Osram and GE so not crap ...........Bloody 45 euros each

Hi me much good Chinese supplier.....you buy from me....me make good led light...I love uk electrician....op beware...needs some careful planing

Should have sorted it out in the last 3 years, mate.
Besides which, I'm always careful with those 3 phase planers....... rip your fingers off in a flash...

Metal halide lamps have an average life of 15,000-20,000+ hours, more than ten times that of incandescent so for worst case, at 12 hours per day, 7 days a week you'd expect around 3 years.

Frequent startup reduces life again but not to values that you describe.[/QUOTE]

who are you trying to kid , i have rarely seen a M-H lamp last more than a year , 6 or 7 months seems to be the norm , i have tried just about every make and 400w PHILIPS MASTER lamps seem to give out the best light and last the longest , as said above change them to 160w twin t5 fitting they give out a better light and he will save what he pays for them in a year.

wouldnt bother with led yet still not reliable enough
