I tested the 490nm module and I can confirm that the wavelength is accurate as described (see figure).Note that you will probably need a heat sink to mount these on.

Flashlight was a nice presentlast Christmas, very lightweight, very bright and very useful. Used every night for pet dogs roundup! LED flamed out one night 4 chips down to one chip lit and weak. Very difficult to identify. Unable to identify so had to adaplt. This is 20 mm diameter, typical 3.0-3.7 volts 3 watts. Modified mounting slightly with very satisfactory results.

Good: Performs as advertised. Bright, true-white light; the steel case I glued it to serves as an adequate heat sink.Bad: Nothing significant.Bottom line: I bought this to replace an incandescent bulb in an old 8mm film viewer/editor that had weakened so much that the picture was barely visible. I was a bit reluctant to use a lamp that runs directly from line current, wondering whether it would need a huge heat sink to keep from overheating. But it does work; the steel case I epoxied it to is enough to keep it cooled, and the wiring job was drastically simplified. I don't think it's perfectly in line with the projector lens, but it's certainly brighter than the old lamp. It's doing the job I expected of it, and doing it well. Five stars.
