Now, Almost all lh-laser use 520nm green laser modules, there is some issues need to clarify.

1. 532nm is outdated green modules, most of manufacturer stop to make 532nm instead of 520nm green diodes.

2. 532nm is not real green, the color with a little yellow. 520nm is real Pure green color.

3. 532nm is not stable, easy to be broken, especially in very hot summer. But 520nm is very stable.

4. The 532nm is much brighter than 520nm for same power.
