New Lighting for the Workbench

I have been looking for a better lighting solution for my workbench.  When I built up my workbench I thought that have three overhead lights would be more than enough, I was wrong.

I switched over from incandescent PAR20 halogen lamps to some Philips PAR20 LED lamps, and there was some improvement but it still wasn't good enough.  The PAR20 LED lamps are rated at 520 Lumens which isn't bad, but the biggest problem is that they are recessed up in the fixture quite a lot and the light gets lost inside the baffle.

The parameters for choosing better lamps were, they had to fit into the existing fixtures (with the trims attached) and they had to be long enough to place the face of the lamp very near the flat surface of the ceiling.

I found the perfect PAR30 LED Lamp made by Leapfrog Lighting.  Right off I was impressed with the technical information that Leapfrog had posted about their products.  Each lamp had a proper data sheet with specifications, Polar Intensity Diagrams, Spectral Power Distribution and Beam Angles.  

I choose the model 1001-P30LC-5001 which has a 5000K color temperature and a 38 degree beam angle.  It is rated at 1000 lumens.

I was very impressed with the manufacturing quality of the lamp itself, even the packaging was very well done.  The lamp fit into the fixture just as I had planed after measuring everything very carefully before ordering it.

As you can see, the difference is amazing.  The 5000K color temperature produces a very bright white light.  I was very careful to consider the height of the fixture above the workbench when choosing the beam angle.  I didn't want to have the light washing off the work surface, this is where the beam angle charts come in handy.  

The Leapfrog LED lamp worked out so well that I ordered 2 more for the other fixtures. 

Here's some links to Leapfrog:

Hello again, I found out years ago, and there are articles about productivity and lighting, that in order to avoid fatigue, your brain needs the right Kelvin grades perception, keep in mind that around. 4000k.....3800k is natural daylight at noon, the 500k is bright but might be a little "thin" in effectiveness, I suggest you mix & match bulbs in your lamps and you will notice better "light perception....perhaps one or two. In the mentioned kelvin range, same lumens.

Hope it works for you
