When someone asked if I could take a look at a 60 effect laser disco light, I was a bit cynical about what it would be like. After stalling for a bit I ordered one from eBay, which came through very quickly in an alarmingly small box.
It turns out to be one of the most exciting laser products I've taken apart in a while. Largely due to the fact that it does have 30 different effects multiplied by a simple red laser projection of the effect and a further diffracted green laser version.
The result is a continuous effect variation with the extra effect of animation of many of the effects just by the movement of the diffraction grating section past the lasers.
It's very bright, which looks great, but doesn't bode well for eye safety or longevity of the green laser module. The current consumption is quite low for the scale of the effect, potentially allowing a long run time on a USB power bank.
The circuit board is clean, modular and functional, with a hidden bonus charger built in for the option of using an internal lithium cell for stand alone operation. It appears they do sell them with the lithium cells fitted.
There's also a mottled red, green, blue LED that provides a wash of light, but it's more of a gimmick. As with many of these devices there's a simple audio detector that will step through the LED colours, alternate the lasers or rather annoyingly, strobe the output.
I'd say that this light is actually worth getting just to see the morphing patterns of the diffraction wheel. It's a very clever effect.

Target price is around £€$20.
