4 Watt C-mount 830nm diode in Host @ 1 watt

So here is a 4 watt 830nm diode installed in this host. The laser is only putting out 1 watt ATM because it is not getting the full amount of current needed to drive it at 4 watts. The host is nice, takes a key and has a blue led indicator light. There is no focusing assembly in place but there are pieces that go with the laser that can be modified to the proper length to place a focusing lens. This will also come with a 18650 battery and charger. If you want to use the laser as is just unscrew the top and hold something close to the diode but be careful. If you would like a spare diode, I have another 4 watt c-mount 915nm diode for an extra $25.

Price-$50 please include $5 for priority mail within the US.

ill take it with the spare diode.
