LED Arrays, constant current, battery operated

5.00 40.00

This was the original LED array design. It uses a constant current source to power the LEDs and technically may be the best way to measure Plank's constant. These arrays proved problematic in the hands of students. A small number over heated. This was a problem we could never reproduce in the testing despite our most abusive efforts. Yet it happened so I took these off the market. I have one of these that I have used for over 10 years with no problems. The buyer assumes responsibility for supervising the use of these according to instructions provided. Batteries not included.
