Tell us about yourself!
In this project I used an LED rated to 500ma and installed a driver at 300ma, derating it by quite a bit. After just a few hundred hours the LED started to dim. I replaced the cheap COB with a Cree CXA 1310 array and it has functioned perfectly.
I hear you and I have experienced that lack of quality control. I've done a couple of other modifications using both the Cree Xlamp and Luxeon high power LEDs on 20mm stars. I'll never go back to the cheap COBs.
Because this was my first conversion, I kept it simple. Just buy a dimmable driver and matching dimmer available at places such as LEDsupply.com.
Wow. I bought mine for$10 at a photo garage sale.
I should have just sold it on Ebay! I had no idea.
As Filmist correctly commented, the body has large slits at every rib for extensive ventilation. And thank you Filmist for the bulb source.
Thank you corporatelab. I believe that we must create objects that are durable, repairable, upgradable and beautiful. Without those qualities, the things we make--and in effect our time, treasure, and legacy--end up in the landfill.
