I have a workshop that is lit by 8 - 8ft fluorescent tubes. Each bulb costs $29. I just replaced all eight tubes with 16 of these COB units for the cost of two of the tubes and there is more light now.

Old_Spirit The shop lights have been installed for less than two weeks and six of the sixteen units have failed. The usage rate is less than 2 hours per day. This makes the LED modules far more expensive than the fluorescent tubes. Old_ Spirit

Old_Spirit The infant mortality rate of these units is very high. I have lost 5 of the ten units in two weeks.

Old_Spirit @J_VDW Ijust found this page. Sorry for the delay in replying. The COBs are bonded to the sheet metal fluorescent fixture using heatsink double sided tape.
