Saw this at Costco in Kenosha today.

I bought a pair of these last month at the local Costco. Tremendous bright light output compared to the 4 foot T-12 florescent tubes I had in a fixture. These LED tubes are supposed to work in any fixture type with no changes in wiring or ballast.

I see they also have them online - but they are $45 for 4 - but free shipping

Here are the online specs

This 4 pack of LED 4ft replacement tube converts your excising fluorescent fixture to LED technology. Direct replacement for fluorescent 4ft T8 and T12 lamps. No replacing or rewiring of lamp holders required. 180° rotating end cap for adjusting light direction with shatter proof acrylic lens. This non dimmable LED replacement tube is UL/CUL listed and FCC compliant. Additional benefits include, 100% glass and mercury free, eliminates humming and buzzing associated with T12 fluorescent lamps, and they last up to 50,000 hours.

Works off of existing ballast

Can you bypass the ballast for these as well? I know some of them will work both ways, but I can't find any information about this one.

I ended up buying 6 boxes last time I was at Costco (12 tubes). I am very pleased with the results. I replaced some older Sylvania Daylight 40 watters with these and they are MUCH brighter and only use 17 watts each. Plug and play, no flickering, noise or anything else.

The old tubes were about 1 1/2" in diameter - the new ones are 1"

I wonder how much energy it really saves when the internal ballast is still being utilized?
