That's a lotta lights! I got pretty much the same bulbs at the same price but from Amazon. Your garage is obviously a lot bigger than my little 2 car. 4 two bulb units light it up pretty good in there and most work I do is in the daytime and the door is open. Bypassing the ballasts was very simple and quick and like I said the best part is instant on with no noise, flickering, etc. Now we're on standby to see if this hurricane is gonna do anything...beautiful day today(if you like hot and humid) but we will see what the next couple of days brings.--Dave
