I have just recently completed building myself a couple of light boxes and I am very pleased with the results. If anyone is interested in me building one for them, PM me and I can discuss price etc, one thing is for sure, they are going to be at least a third of the price of imported ones, and IMHO work just as well. The two attached images will give you some sort of idea of my construction. My method of construction allowes the light box to fit over the front of the telescope/dew shield, much like a cover so one does not need to balance it on the scope.
I use a 12v lighter type connector for the power, and each LED is rated at between 6000mcd and 12000mcd depending on the size of the box required.
If interested please feel free to ask any questions.

I'm new to this forum so I must be missing something. What is used to ensure that the light is evenly spread in the light box? As what I heard, even high-end computer and phone screens have about 2% uneven in brightness. Isn't that going to be an issue?
I use Leds reflecting back on the inside of the rear of the light box and that light is further diffused by a "diffuser" it just works well, I have built over 400 of these for astro photography and have rarely had any problems. Only time was when a guy left his turned on for over 3 months and the Leds deteriorated, I replaced these for him and as far as I know it still works well.
I have built these for scopes as small as 50 mm right up to 14" plane wave beasts.
Hi Peter, I have a Meade LX200 10", would like to know if you make light boxes for this scope. External diameter is around 30.2cms if I measured it correctly, (can confirm). Thanks.
