There's nothing like being able to see your 3D print clearly as its being created. We've tried positioning desk lamps, and bought floor lamps, but nothing works as well as LED lights on the printer or inside the enclosure.
LEDs are hot right now and you can find them for sale all over the internet. We tried a half-dozen before setting on this model as being perfect for 3D printers.
The 2m length is long enough for even the largest printer.
The width of the strip fits perfectly inside the 20/20 rails so no adhesive is needed.
It *has* adhesive should you want to place them somewhere other than inside the 20x20 rails.
It has an extra-long USB-A power cable powered by any USB power supply. (Power supply not included.)
While the lights are only available in white, that is the perfect color for keeping tabs on your prints. While it seems cool to try green or red, alternative colors quickly get old and make it difficult to see your prints.
