    Contents of the package was as advertised. But I still need to get heat sinks for them. I would like to upload a picture with them lit up, but I just want to be Shure about what I'm doing when connecting to the LED power supply I ordered. still a lack of information included in the packaging. Because of this reason I can't really comment on the overall Quality of the product.

    Fonctionne très bien, tel que décrit. J'utilise un dissipateur thermique pour processeur et le ventilateur est obligatoire.

    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.

    I bought the 30W model. The LEDs start at about 27 Volts, so you will need to run these at over one Ampere to get 30W input. Really, though they are very bright and after some experimentation, I have decided to run these at 600mA, 30V. They should last forever at that power and they put out lots of light.
