I was looking at the Muchmore LED light pitboard but the item is out of production and also very expensive. So I was looking at alternitives and came out with LED panels. Over here not all sizes are available but I could get a 60x60cm plate. It costs about 30 euro with a 220v LED driver.

It is a huge light source so a dimmer would be pretty which is an option. From Ebay you can order an adjustable CC/CV boost converter for just a few bucks so I can make it adjustable and working on a 12v source like most have on their bench.

On Alibaba I have found better sizes like 45x45 and 50x50 so If I like it I will order one of those
