Wow! I never knew they even made such a thing. My kitchen alone uses 600 watts worth of florescent tubes. And I have 3 work shops that I don't remember how many of those tubes they use. I suppose you can't just replace one at a time, eh?
I had a bunch of the two florescent bulb shoplights in my shop for years and they always sucked! They always needed messing with, wiggle the bulbs to light, never wanted to come on in the cold, expensive to replace the bulb. And because of the laws in NY I had to hold onto the old ones and once a year register with the county to show up in a 30 min window on one certain day to recycle them, it's the only legal way to dispose of them here, the trash guys won't take them.
Finally a couple years ago I found Ace Hardware had these on sale, in fact, son of a gun.... they are on sale again right now! BTW, it says with Ace Rewards (sign up online or while there) you'll get another $3 each off that price, so $20... can't beat it, I paid $25 each on sale last spring LoL. Better run, I bet these will sell out fast!
Metalux 43 in. 32 watts LED Shop Light - Ace Hardware
I first bought four, loved them! That replaced half my lights, last spring Ace ran the sale again and I got six more and replaced all the old lights and adding a couple more. Now its like daylight in my shop, never ever been so bright and they cost a fraction to run, plus it can be 10 deg below and they come on full bright instantly. No more wiggle the bulbs, waiting for them to come full bright, no more messing to get rid of old bulbs.
Each only uses 32 watts, each puts out 3200 lumens I can run all eight and use less then juice than it takes to run three 100 watt bulbs. I kid you not my entire shop is as bright as a sunny July day at high noon.
