The spectrum from them is not too lumpy and the color is similar to real daylight so in my opinion not over-blue. > For ceiling mounts, the flat panels (behind diffusers) give you > the best lighting efficiency, because the LED's aren't arranged > to try to throw lumens in all directions. I had seen some with a plastic base with metal contacts that attached to the end of the PCB. I considered those but didn't like the joint. These with a PCB trace making the contact is about as simple as it can get. > A buck a throw sounds good. Mine were _way_ more than that. > I think I spent around $200 for the conversion. Two years ago. In those two years the market has changed!! Actually, I found these on a whim. I was taking the COB panels rescued from medium base 120 VAC lamps with failed drive circuits and rewiring them to be better suited to a resistor limiter for 12 VDC. To drive them bright uses a lot of current - at least compared to a historic 20 ma LED drive - so my stock of 1/4 and 1/8 W resistors were insufficient. I priced the resistor I needed, and then on a whim check Amazon for complete assemblies since it had been a year or two since I last look. I was quite shocked to see ready to install, no modification, regulated lamp units for less than the resistor I was about to buy! I still built one with a resistor limiter so I could make it _very_ dim to use as a night light in the center fixture. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
