High Bay Lighting

Over the past few months I have started to see many more T-5 fixtures going in as replacements for HID fixtures. One of the school districts we are working for replaced all their HID fixtures in their gyms with these type fixtures. One reason would be a 60% energy savings over HID fixtures,The other would be there is no start up issue as with an HID fixture.

Most of these I have seen are also Universal voltage (120/277) so there isn’t an issue of rewiring them and makes them great as a replacement.

More Lights

Today we went to another one of the schools we were working at over the summer and replaced some more lights in a kitchen. This one had surface mount lights we took down and replaced with some lay in fixtures. The school board is trying to cut cost's by replacing fixtures or replacing ballast's in many of the schools as possible. When you get a large number of ballast's the cost for electricity is pretty large. It seems like we are getting a lot of these types of jobs now since new construction has slowed down so much.








Yesterday a reader asked about LED bulbs as opposed to compact fluorescent bulbs.
LED bulbs will save you more than a CFL but they are still relatively new so their prices are still kind of high in my opinion and I would guess over time they will go down as more brands become available. I do have some LED night lights installed in my home and I love them.

Getting Ready For School

This was a school we worked in for the best part of the summer, We had to change all the ballast's and re-lamp all the fixtures in two complete schools and one bus garage, it was a total of about 2500 lights in all. The worst part about the ones in the picture is they were a "re lock" system with the plastic quick connectors on top "277 v" but since 1978 they had seen one to many tugs or what have you when ever someone was above the ceiling and many of them had become loose and or shorted out. So we had to cut all of the old connectors off and strip out the BX and put new MC connectors on everything, the good thing was it was only one school like that with 1200 lights but it was very time consuming.
