I think 520nm is better,but i think seller is wrong, because price for 520nm is always expensive than 532nm (if less than 100mw)

Welcome to forums,i also have 490nm ,that is fine for you?

sanwu have single mode laser and mutil mode laser(low-high-turbo-sos) and it is he's mean,not single and mutil mode diode

BUMP for my Green laser 1W+ :p :p :p :p

Thank you for let me know ,😊😊😊😊

yes, it isn't CC driver ,also don't have VC driver,but i can drive with IR,i tested, red laser with 2.6V can work wiht 4-8v input with LM317 did you have any test to prove that it will break the diode?

Edit:

okay bro

that fine bro, If you still want to red 1w from me, I will probably provide 1 purple diode included in 1 12mm copper module

if you fine with mutil mode diode please use sharp 350mw 405nm,set driver at 700ma,it is fine for 1.1W
