Anyone have experience with these modules?

[Johanneson Apple]

For my ultra-cheap polygon scanning laser projector (salvaged from a printer), I’m looking at RGB modules. I’m running a 300mW module which is not bright enough for anything outside of a pitch black room. The colors don’t pop. I’m debating just buying laser diodes and machining a copper block, but all in it seems easier and possibly cheaper to just buy one prebuilt and message the seller to send the RGB unit without the driver.

I have an Optlasers 1A 3 channel driver.

The laser module I’m considering buying is on eBay. It’s called “RGB 2W 3W Laser Module White Red/Green/Blue Light 12V TTL Control” (can’t post the link yet), and I would buy the 3 watt version.

Bump.
Also pics will help..

They work as intended.. got quite a few of these RGB modules over the last decade
They perform around their specs. and most will accept PWM/TTL modulation and the more expensive also analog mod..
Got them from around 300mW up to 17W and some are wide-beam..

Bang for the buck, you do get a lot.
This 5W 4-diode unit was around 80$ on Aliexp. a few years back (incl. 25% DK/EUVAT) Performs around 6 to 6½w out of the box.

You can suit them up with RGB drivers with trimpod-control if you wanna optimise for certain hue/color and don't wanna bother with modulation.
They are around 8 bucks.

The quality of the RGB beam-alignment varies from unit to unit.
