I can see only 60 LED (not 145). Very Happy

I wonder if the number 60 is somehow related to your 120V power system (the other lamp you've posted today has the same number of diodes - 6x10 pattern)?

They use the same LEDs but driven at different powers via the different outputs from the ballast. So you could rewire this fixture for a higher or lower output using the same number of LEDs. The lower the output the longer the LEDs will last though.

Wait. I thought LEDs don't use ballasts. I thought they used LED drivers. My GC1 I got for Christmas 2013 has an LED driver in it.

A ballast and a driver are the same thing. Rolling Eyes

Hmm. I never thought of that. On the other hand, LED Drivers are much lighter than HID ballasts for Mercury Vapor, High Pressure Sodium, Metal Halide or Low Pressure Sodium.
