Some of my kids are reaching that age where black lights are so cool, and have collected a few glow prints as well. Made up a simple modular light bar that holds two 8mm LED strips and connects to a very small box to drive them. The angles are such that the UV light is pointed more directly back while the white light still casts out at a more usable angle for reading without being directly in your line of sight.

The box has a mini PWM motor controller and SPDT switch to control dimming and select which LED strip is enabled. Power is provided via a 5521 jack. No glues or screws are needed for assembly, only some VHB tape to mount the bar in it's final position. Because of the shape of the bar, you don't need adhesive strips for this to work. They slot in and are retained, so they can't fall off or sag.

Included are the following parts:

• Red - the “male” bar has one end closed and one end with a male component (I didn't use this).
• Green - the “extension” bar is male one one end and female on the other with no closed ends (I used two of these).
• Blue - the “female” bar has one end closed and a female coupling on the other (I used one of these).
• Yellow - the “box” is the electronics enclosure
• Orange - the “lid” is the snap-on lid for the enclosure.

Each bar is 8" (203mm) long, so figure out how many you need. The print profile included has all the parts necessary to make a 2' (0.6m) light with the control box on the left.

Assembly:

1. Snap your bars together and feed in your LED strips. Cut them to length.
2. Pull them out and solder lead wires on to them. I gave it about three inches.
3. Put the strips back in the bar and snap it on to the box, carefully pulling the lead wires through the diamond holes.
4. Wire as shown (depending on your DC jack you may have to install it at this stage):
   
5. Install the switch and PWM driver in to the box, tuck the wires away.
   
6. Snap on the lid.
7. Add VHB tape along the top of the lamp and stick it wherever you need it!

I threw a 4000k COB LED in one slot and a UV SMD LED strip in the other. Brims are enabled in my profile so you'll need to clean up the edges a little with a hobby knife after printing. The parts should snap together with a little effort (there is no tolerance in the model!) and hold snugly.
