Well there ya have it the led wont work. Did you have a direct led or dispersed led array GG?
I see some of the led lighting strips have a 30 degree to 50 degree lighting "cone" I guess.
Wonder if this plays into the solution.
My range is 50 miles from the house, I dont have a generator and wont spend the money to get the special light bulbs so I guess Ill just have to rely on ole mother nature and cloudless days
I have run into the same problems with my Oehler on overcast days and fading sunset light.
