Full post on this project with instructions here: https://www.i3detroit.org/wiki/User:Mkfink/LED_tube_fixture Short video about it: https://youtu.be/W45qHghIwp8 I designed this after receiving a donation of multiple pallets of T8 LED bulbs and not having any fixtures for them. Since the bulbs themselves are rigid aluminum tubes, I figured I could get away with some small, 3d printed adapters to connect to the bulbs on the ends and hold them together. It additionally requires two sockets (Leviton 13351), four #6 x 1/2" pan head sheet metal screws (not self-drilling), some wire, a plug, and optionally a sonoff basic to add wi-fi control. I designed it to use the shell of the sonoff as a cap, but I also included an STL of a plain flat cap for use without the sonoff. Update: Added a variant that holds 4 bulbs instead of 2. Construction method is similar, but the spacer is now screwed to the case with four #6 x 3/8" pan head metal screws. On the other end, four #6 x 1/2" screws attach the spacer to the bulbs. Update 2: Added revision 2 of the 2 bulb fixture. Changed it to screw together like the 4 bulb one does. So print 1 case and 2 spacers. Use #6 x 3/8" pan head screws to connect one spacer to the case. Update 3 (2021-06-03): Added new versions (v2) of the 4-bulb case and cover. The cover attaches to the case much more easily with a few snap points instead of sliding on.
