Alternative to 3 pole terminal strip that takes less space
8mm LED connectors - to split - 2 packs needed for 2X box with 24 strips
Assorted metric screws, nuts and washers
Note that if you opt for the 4X speed box with 48 strips, you will need twice as many connectors!
Also note that if you opt for using the Waveform Lighting strips, they are wider 10mm strips and will need different connectors:
Spade connectors for AC connections inside enclosure
Alternative heat-shrink spade connectors
Fork connectors for connecting both AC and DC wire to the power supply
Universal power cord to supply wall current to box
Cable clips to keep wires tidy
Inlet plug module to connect power cord to box
A slightly more expensive, but easier to wire inlet plug module from McMaster-Carr
Mounting brackets for Meanwell transformer
Meanwell 350W Transformer for 2X speed box
- OR -
3 Noctua super quiet 60mm x 25mm fans This fan is slightly chunkier but runs more quietly.
16 gauge wire for AC wiring inside box
20 gauge wire for DC wiring inside box
Rubber edge beading for bottom of box
3M Double-stick tape for attaching terminal blocks
Other options for connectors

The first entry here is a new one, and quite a surprise! Recently, a friend brought by some 365nm LED strips that he had located online. We decided to test them against the pricier options already installed in my exposure boxes. I have a UV light meter, and we tested the output of these diodes against the Inkjet Mall strips. The bottom line is that they seem to be a very similar product. They have the same LED type and LED density per meter. When I built a full box using these LEDs, they measured slightly less light output - about 75% of the output for the same strip spacing as the Inkjet Mall strips.
But the big shock is the price - they are ΒΌ the price that Inkjet Mall sells theirs for! Your 2X speed (11mm spacing between strips) total LED cost would be ~ $175 including shipping, versus over $650 for the inkjet Mall strips.
The key differences as far as I can see is that the power consumption per reel is slightly higher than the Inkjet Mall strips and the output is slightly lower. The product listing indicates 120W/reel of power consumption, which would mean that to be safe, it would make sense to get a 600W transformer instead of the 350W, which would support up to 4 5-meter reels of these LEDs.
This represents a huge savings in the cost of building an exposure box!
Here is the website - be sure and specify 365nm lights - which have a $20 upcharge over the default listing. There is a pull down selection box on their web page.

The UV-LED strips can be bought from Inkjet Mall here:
3 5-meter reels of 365nm UV-LED lights
3 reels are needed for the normal 2X speed version, and 6 reels for the super-fast 4X version for the 20x30 box. The 17x25 box needs 2 reels for the 2X speed version and 4 reels for the 4X speed box. Note that you will need more connectors, and a larger transformer if you build the super-fast version:
