Tenergy Lumi Bloom Table Lamp as a Ceiling Fixture

thingiverse

#About# Modification of electrical fixtures and appliances is done at your own risk. These parts were designed to convert an inexpensive, modular table lamp to a ceiling fixture. The table lamps themselves are great, with branches and bulbs using the same socket base so you can create your own tree-like lamp structure and change it up at any time. This modification allows the lamp to run 120 volt bulbs into the house electrical rather than 12 volt bulbs via the included adapter. If you're not comfortable making this change, please refrain from undertaking this modification. While this modification enables you to purchase multiple lamps to add more bulbs to one ceiling fixture, take note of the combined wattage of the bulbs to limit the number of branches and bulbs you include. Tenergy Lumi Bloom Table Lamp: https://amzn.to/2M1LkOM Alternate 120 Volt Bulbs: https://amzn.to/31U5jFO #Assembly# ##Bulb_Socket_Spacer_Adapter.stl## This lamp uses 12 volt bulbs, which have longer bases than 120 volt bulbs. As a result, 120 volt candelabra-size bulbs won't screw deep enough into the sockets to make the required connection. To solve this problem, I designed a threaded spacer with a hole in the center that glues onto about 3mm of a nail's base (all but 2mm or so cut off). The flat of the nail sits on the socket's center connection when the shim is screwed in, and the pin of the nail is where the bulb's center lead will sit when the bulb is screwed in. The nail bridges the electrical connection while the spacer screws tight into the socket, preventing any shorts. I used 1" 2d nails labeled "Krazy Glue" and they fit quite well, but I glued them anyway to be extra cautious. Both the cap and tip of the nail may need to be scraped or sanded after gluing to ensure a good connection. One shim will be required for each 120 volt candelabra bulb used with this lamp, but when connecting a branch to a socket rather than a bulb, you'll need to remove the shim. Consequently, when re-configuring the lamp, you'll end up shuffling the shims from socket to socket. When inserting these shims, screw them in reverse a couple turns to get them level, then they should screw in properly. Don't tighten too hard or you'll risk cracking the shim; snug is good for making the connection. These shims have a slot so that a flat-head screwdriver can be used to insert and remove them. **Ensure the power to the light is off before removing or inserting any bulbs, shims, or branches.** ##Fixture_Spacer_Shim.stl## To use this lamp as a ceiling fixture, you must remove the base plate and power adapter socket. Then, print this shim that will brace the lamp against your ceiling and has holes 89mm apart for connecting to the electrical fixture box in your ceiling. This shim acts as a brace that allows you to tighten the fixture without fear of bowing the plastic base. Once you've printed this shim and checked it against your electrical box, use the holes as guides to drill through the base of the lamp. Drill slowly, and I wouldn't recommend using a punch since it might crack the plastic. ##Bolt_Cap_Base.stl## ##Bolt_Cap_Cover.stl## This cap and cover allow you to hide the bolts that must go through the base and the shim to connect the lamp to your ceiling electrical fixture box. Insert the bolt into the base, mount the lamp, then place the cover on the base. It should friction fit and give a nice finished look to the fixture. ##Power_Adapter_Cover.stl## This small piece fills the opening left after you remove the 12 volt adapter socket from the base. It simply slides into place. #Printing# I print rafts with most things, including these models, other than that they are quite simple and shouldn't cause any issues.
