22*70mm Fat Beam 405nm 250mW Dot Laser Module

wavelength 405nm
output 250mW after the beam expanded, the output must be reduced to 100-150mw
working voltage 5V can work with one pc 18650 li-on battery
diameter of the beam 14-16mm
size 22*70mm
working current 300mA
ld NDV4512 Nichia
storage temp. -40 - 80℃
duty cycle 4-8hr on you can prolong it by adding heatsink

Note:
all fat beam lasers normally used in fog or smoke area, so that in those areas, the beam can be seen. if you use it in open and bright area, you man cannot find the laser beam
