Review on 6&quot Industrial Electrical: Powering Efficiency and Reliability by Josh Schaefer

First pluses: great price, fantastic light, easy installation. Bad: Description of dimmer compatibility is not entirely correct. I have installed seven lamps connected to a LUTRON DVCL-153P dimmer which is on the recommended dimmer list and there are two problems with the light turning off AFTER it has been dimmed: 1. If the light pre the power off is reduced to about 50% , it is more does not turn on. GENERAL. You have to turn off their dimming to turn them on and then dim them back down to whatever level your heart desires. 2. The more lamps are dimmed, the longer they shine. The lag is very noticeable, enough to be an annoyance. I have another set of old headlights hooked up to the same dimmer and they turn on instantly at any light level so I know how it can and should work and these bulbs DO NOT WORK PROPERLY. Alert everyone to the problem. It is unacceptable to discover such problems AFTER INSTALLATION!
