Used two of these in a custom lighting rig for a small Christmas nativity scene - perfect even brightness.

Très pratique, ses dimensions réduites facilitent son implantation sur les projet. Sa luminosité raisonnable en "blanc froid" me convient.

This is a relatively bright LED module when powered properly... I'd note that the data-sheet indicates a normal operating voltage of 3.2V, 20mA draw - 20mA is more than the 16mA you can safely draw from a GPIO pin on the Pi. You'll need to under-voltage it if you want to power it from GPIO - which I have managed with a 100Ω resistor. Looking at the data-sheet I've probably dropped the LED down to a voltage of 2.9V (@4mA) which about halves the brightness (read the datasheet - this is all non-linear graph guess-work!). You can reduce the value of that resistor to increase the brightness, but then you're in the twilight zone of the manufacturing tolerances of all the components and might fry your Pi. So - yes, it's good; no don't recommend it for a Pi; but my stupid fault for misreading the datasheet!

I'm sure you are not receiving 60 units orders everyday... but I'm using this to iluminate lego buildings :)

I bought a few of these on another site before they were available here. They are amazing and very bright, providing a perfect directional light source for projects that require this. Would definitely buy more of these
