Not happy with CFL lamps but still want an a cheap energy saving option?

If you have tried CFL lamps and are not happy with them but don’t want to go with expensive LED lamps to save electrical cost why not try Halogen Incandescents? Halogen incandescent lamps use a halogen gas filled envelope to reduce the amount of energy needed to give a light…

New CREE CR6 LED Modules for 6 inch Recessed Lights

Here is a short video on the new CREE CR6 LED modules designed to fit in existing 6 inch recessed light housings. These should be on the market by the end of August. We have a sample on order and will update our blog once we give this new product the once over.

Induction lighting technology reduces energy and maintenance costs

I’ve been interested in induction lighting since first reading about them. We were lucky enough to have the chance to install a couple of them in the main waiting room area of Bridger Orthopedics. It’s been over a year now since the install and we have not had any issues with them.

For that project we selected the Phillips QL 85 light. The complete package includes the generator, the antenna and the vessel. You can see those devices in this short youtube video.

The project at Bridger Orthopedics was actually a retro-fit job on two separate fixtures. The fixtures were existing and used a 400 watt metal halide lamp to provide up-lighting on a wood ceiling. We removed the metal halide lamps, disconnected the ballast and installed the Phillips QL 85 system. The light output of the QL 85 was not quite as good as the 400 watt metal halide but was certainly sufficient for the task. Unlike a HID style fixture, the QL 85 had a very slight warm up period and will re-start almost immediately if power is cycled.

Now to the really good part… the QL 85 unit has a rated lifespan of 100,000 hours. A typical metal halide lamp might last 15,000-20,000 hours. Servicing these lights required the use of a lift and could not be done during normal business hours so, by removing the metal halides and replacing with the induction lights, we have greatly reduced maintenance cost. We also dropped the electrical load 630 watts (315 watts per fixture). That’s not only 630 watts of direct savings on the utility bill it’s also 630 less watts of heat the cooling system had to offset during the summer months. The reduced maintenance needs and the reduction in electrical usage by these fixtures and the HVAC system makes this retro-fit a real winner.

The bad part? If I keep putting these I might just work myself out of a job!
