1,6W 525nm green laser diode

[Miya]

Update ! 525nm 1.6w diode is NUGM04
2W at the 2.5amp with Gball lens
2.2W at the 2.8amp with Gball lens

I have had the 525nm wavelength lasers and they're not as bright and visible as the 520nm.

NUGM04 it's the same NDG7D75T ?
NUGM04 somebody did a test ?

NUGM04 is a diode block. NDG7D75T is a diode by it self. By looking the specs for each of these, it is very possible that the NUGM04 block uses the NDG7D75T laser die, but its hard to confirm.

Right--they are brighter. lol
A 525nm of a given output power is brighter than 520nm of the same output power to "normal" eyes as it is closer to the peak of eye sensitivity of 555nm.

aliexpress and ebay sell NUGM04 no one bought to test ?
