Re: Introduction to LED Lighting Recording Is Up!

I recently completed the renovation of my museums entire lighting grid with both retrofits and the new LSI all in one LED fixture that Rick spoke of. During my many tests of the various retrofit bulbs, one of the bulbs I tested not only had the plastic casing fins start to melt, but it also began to ooze phosphor out of the back of the bulb. Having had many conversations with LSI and reading Druzik and Michalski’s Guidelines I was already aware of the color shifts and deterioration of light quality that would happen if the phosphor started to degrade. This particular bulb had been installed in an open back gimbal style fixture with plenty of air circulation. The melting of the casing happened over a period of two months. Be very careful using your existing can style fixtures with your LED retrofits and for now test everything.
