Just back from Lowe's with a two pack 4000K.

They have quite few of four packs.
6500K $17.48
5000K $12.49
4000K $12.49

Make sure you check the spec so you know what you are buying. Also read post below.

Now I read this part.

Single bulb Item # 778115
T8 LED tube with dual installation method - T8 direct-replacement or ballast bypass


two pack Item # 778114
Operates directly off existing T8 electronic ballasts, quick and easy installation

Better read the four packs before you buy which is which.

Talking I think I'm all set for a while...

Took a detour in my travels Monday and bought out a Lowe's of these (27). Guy had to get the special man lift to pull another 2 dozen from inventory. Final tally was $3.79 each (no tax and 5% Lowe's CC discount). Spent a little over $100...

PS: I'm just thinking about all the cheapy 48"x2 fixtures I've thrown out over the years because the ballasts went... I do believe I have one in the loft where only one half of it works. I'd been using it to test 4' bulbs to see if they worked (in the working half). Guess I won't have a need for it anymore...to test bulbs that is! It will be going right back into service sporting LEDs!

In related news, I had to replace a ballast in an 8' fixture a few months ago. That was about $30 if I recall correctly and it wired in differently than the old one so that added a little complication...

Just ordered 10 of the $4 direct-connect singles for store pickup. Have to drive to a store 20 miles away to get them. 5000-6000K would be nice, but I can live with 4,000K.

Smile 2 down, 25 to go...

Had this aforementioned fixture that only worked on one side. Definitely NOT meant to be serviced as it took me a little bit to pry both ends apart!

Once apart, both ends had what looks like a transformer, a capacitor and a little circuit board. Removed those and the wires running from one side to the other. Lightened the fixture about a 1/2 pound!

A few butt connectors and some electrical tape and it was good to go! I also tied the wire in a knot to act as a strain relief.

Way to repurpose! Are the ends of the bulbs taped up for some reason? Did they not work in your tombstones?

Default Lowe's 778115 LED 48" Bulb (for the search engines)

Refer to the pic of the "back" of the bulb below. I hadn't really noticed the tape until I put them in the fixture and took a pic and was like "hmmmmm". Beneath the tape is some obvious circuitry and wiring. You can also see the mounting point for the LEDs running the length of the bulb.

I can't remember if the 2-pack bulbs had the tape at the end or not. Perhaps dimwitted consumers were enraged at the missing 1-1/2" of light they were getting shorted out of so they discontinued them rather than face a lawsuit! It is also hard to market a 46-1/2" bulb...

Also note the 3/4" and 1" conduit mounting clamps and 3/4" connector and cap. The 3/4" "hard"ware fits over the ends of the bulbs perfectly and the 1" fits over the 3/4" connector and cap. It would be easy to make a 3/4" conduit "handle" but I would fear it would rip the end of the tube off! And the pins the butt connectors are pushed onto appear fragile and did spin when I tried twisting the butt connectors on so there is that... But unlike a flourescent tube that would implode/explode if you broke the end off, I would imagine these could be repaired and still provide light athough they may not fit in a fixture anymore...
