    Good Stuff. Forgot to order the drivers. I have some CC/CV boost or buck converters I can use until I order the right ones. Thank you BangGood.

    I am an electronics engineer. I analyzed the 30 watt LED chip. here are the measured values. The LED is mounted on a large heat sink. 20 x 6 x 6 cm. 31 Volt - 0,3 Amper = 9,5 Watt 32V x 0,4A = 12,8W 33 x 0,54 = 17,8 W 34 x 0,67 = 22,8 W 35 x 0,795 = 27,8 W !! According to the manufacturer, the chip may only reach a temperature of 60 degrees. This is standard and must be observed! The chip can be operated with a maximum of 11 watts on this passive heat sink. He works like this for many years! With

    surprisingly tiny and very bright. NEED BIG HEATSINK. no way to mount to heat sink other than glue. not sure how long it will last as it is a lot of heat that needs to go to a big heatsink from a small area.
