I have the Sam's club 4' lights (with the tape lights inside and throw away). I replaced six 8' T12 double bulb fixtures with 12 4' LED Fixtures.

I'll tell you what, I am VERY HAPPY! They are installed in 2 banks both on separate light switches. I replaced one side first to do a comparison.

Three 8' double bulb T12's = 3.6 Amps
Six 4' double row LED Fixtures 1.8 Amps

Folks that is HALF the cost to run.

Now for the illumination...

The T12's I have are rated at 2300 Lumens (which drops over time and is de-rated the colder it is.

The led Fixtures (Lights of America 4-foot LED Shop light) from Sams is rated at 4500 Lumens NEVER DE-RATES UNTIL TOTAL FAILURE

So as a comparison...

When new a 8' T12 Double fixture is 4600 Lumens
Two 4' LED Fixtures is 9000 Lumens

All I can say is I have been running them in my shop for a couple years now and I have had no failures or reduction of light output. As a bonus they light up 100% brightness with no buzz and flicker when cold like the old T12's.

I cant complain about twice the light for half the cost to run them either!!!!!

I don't have pics of the lights handy, but here is a picture on the shop.
