[labnetwork] LED lighting

[Dennis Schweiger]

Shawn/Christopher,

I've attached the lamp we used (97829, and 57839).  We retrofitted a
ceiling full of T-12 fluorescent to LED, and installed new "yellow" sleeves
(Tarp50) on them for the areas that we wanted to remain photolithography
compliant.  We also retrofitted about a dozen fixtures where we had T-5
fluorescent tubes with LED bulbs. There were over a 1000 bulbs installed on
this project, and in the year that they've been installed, I've had to
change out three bulbs.  That's not bad considering they're on 24/7/365.
When we had fluorescents, we were changing about 50 bulbs every six months.

We tried some of the 57840 lamps, and found them to be acceptable, but when
we looked at the install costs, it was considerably cheaper to use the
"white" bulb with the yellow sleeve, and this provided more long term
flexibility if we wanted to "change" other areas to yellow at a later date.

As part of this retro fit, we also modified some of our existing lighting
fixtures (about a 100 of them) to go from a 2-bulb design, to a 4-bulb
design.
