I've owned three different types of LED panel and all of them had different chips and ratings.
So a bit of investigative work or 'close observation' has led me to the following conclusions.
Item #1: MarsHydro UFO led 100w power consumption is 60 3w LEDs driven at 1.66 watts each.
Item #2: An LED light bulb 23w power consumption is 12 3w LEDs driven at 1.9 watts each.
Item #3: Sunspect900w panel 339w power consumption is 150 3w LEDs driven at 2.2 watts each.
Conclusions:
There are 3 different ratings for 3 watt LED chips depending on their manufacture. To get an idea of which type you have, you need a magnifying glass to look at it closely, and if possible make a visual comparison of the size of the chip or chips. I include a few photos, the first image is a comparision of the LED grow light bulb versus the Sunspect panel. It can be clearly seen that all 3 watt LED chips are not equal. Basically the more surface area the chip or chips have the better their rating and power output can be.
