i think the LED drivers only list a maximum wattage. since the driver is pretty much a step-down transformer, i think as long as you stay under the max wattage you're good.
OUTSTANDING SOLDIER !!!! I'm going to contact either AEL or Holophane to see how to get a replacement LED board and see how much they cost in case I might need one in the future.
My beta LED light up in my yard has three driver setting so I can change it from 35,52, or 70 watts. Currently I have it on the 35 watt setting. Lights the yard up very well.
