I'd like the tubes in my lab replaced with LED's

I have NO idea how long they last either having 80+ in the lab and 3 not working this week. Those loko a bit dim so could have been up there for 5 years or more.


In my lab typically anywhere from 3 to 6 fluorescent tubes (not fittings)
go every year and replaced by maintanace, we do not have to pay for teh tubes

Fluros should be batch relamped, by time their dead enough to flicker they are down to nearly 50% of intial output. Rolling replacement of % every year But people think only dead lamp lamp is one with no light coming out.

Tend to be more carfeul with metal halides that if left long enough will remind you a lamp change is required with a bang.



and has LEDs on the roof garden which are alight with no one on the roof garden so they can afford LED lighting .

The architects like LED lighting thats whats important not what the users need, suppliers didn`t stock PIRs... ;-)
