Good to see these diodes are now available for a reasonable price (200?). 515nm is a pleasing color and I hope to possess one of these diodes soon.

They are relatively inefficient however - > 1/2 watt (~660 mW) is required to produce 25mW of light, and around 6 volts necessary. Despite this I see no reason these diodes will not be pointerizable, however the battery life will not be very good.

As for the 5.6mm package, I guess it's because they bundled the photodiode inside, instead of the early ones of 3.8mm.
There are two types of Green diodes:

- The Osram diode, tested by rhd & aryntha in the 3.8mm package
- And this 5.6mm diode from Nichia

They´re two different diodes from two manufacturer.
The Osram diode is the one getting cheaper according to this article

The Nichia is still $$$$

That's great that they're getting cheaper but that doesn't matter if no one is selling them...

I am glad we have now two manufacturers. That would speed up the production and bring down the prices.
