The CREE LRP-38

November 12, 2009

We can’t tell you  how excited we are at Cree’s achievement in the LRP-38 LED lamp.

Originally we saw this new technology at LightFair and were cautiously skeptical.   Show booths are of course designed to make things look the best they can – hiding every possible flaw.  Further, it’s very difficult to evaluate color temperature and output when your standing in the middle of a convention center. 

Cree’s display for this lamp consisted a multitude of these lamps landing on a bunch of fruit demonstrating its application for the grocery store market place. 

To be honest, at the show, I thought the lamp looked like it might read a bit too pink off the trade show floor. I knew I had to reserve judgement because I realized I was also immersed in cool color temperature metal halide. Fortunately, Cree agreed to send us a sample of this lamp to review.

So we mocked it up in the toughest environment for LEDs possible … residential.   This is the domain of the incandescent and halogen bulbs.   The results,  I have to tell you,  were very impressive.   We put this 12 watt lamp side by side with a 50 watt 25 degree halogen IR. The output was very comparable. It appeared to us that the Cree color temperature was ever so slightly pink compared to straight halogen but definately, in our opinion, a workable lamp in residential and hospitality design projects.

The LRP-38 beam spread was exceptionally smooth.  It far surpased it’s halogen predecessor in that department.  The glare control is outstanding due to the design.   The LED is actually in the fin in front of the reflector and aims backwards not towards the occupants in the space.    Awesome!   We can’t wait to see more bulbs in this family. 

Congratulations Cree!! on an outstanding accomplishment in LEDs.

And, more good news, the box comes labeled with a lighting facts label. How will this affect consumers in the future? See our post Legislate this!

Don’t want a headache from your LED task lighting? …

June 2, 2009

Then you’ll need to be aware of this…

Some LED linear lighting fixtures used for undercabinet lighting produce what is called multi-source shadowing.

It looks like this:

This is because they use many smaller points of light that have a directional quality.

Regardless of the color temperature or output, we bet this would be very likely to give just about anyone a headache if they are working next to it.

So while you’re testing for color and output, you might also want to take a look at the shadow pattern you’ll get. It varies with the configuration and treatment of the LED lamps in a fixture.

Some shadowing may be tolerable for an application but it does need to be considered in your selection.
