GU 10 or Led Screw
I am considering ebay and warm white GU10's on adapters for most of the main day use bulbs. I was wondering what wattage would be adequate for day use in 8 and 12-14 foot ceilings. The bulbs come in 3, 6, and 9 watts usually and are about a dollar a watt.
Any ideas? I plan on using 3 sola tubs as well as quite a few windows.
