2010年4月9日 · (Failed to include battery or charger) DX: SD Laser 301 Price: $31.90 Claimed output: 50mW Power source: 1x18650 Adjustable focus (included battery) I specially requested that an IR filter be added to the Rayfoss unit before shipping.

2017年12月16日 · A laser 301 stopped working? Considering those are only like $5 I would just buy a new one. Not really worth it trying to fix it. The best you can do is check the battery contacts and make sure it has a solid connection. Does the battery seem secure inside the laser?

2011年3月11日 · In the beggining the laser was cold. After 5 min it's "not cold", but not warm or hot. Ok, it might be bad contact between the heatsink and this part of the laser. I touched the whole laser inside, outsite, the battery, and everything was as cold as usual. I assume, then, that the laser has a fairly long duty cicle. It's a great laser for the ...

2013年10月20日 · It depends on the laser design. CR123 and 18340 are the same physical size. CR123 is originally a description of a primary (non-rechargeable) lithium cell that was often used in photo camera's and such, and has a voltage of 3.0 volts, fairly constant from fresh to depletion.

2014年6月20日 · I have a SD-301 200mW 532nm Single Dot Green Laser Pointer coming from Fast Tech, and noticed there weren't any details on what kind of 18650 is best for this device. I've got a few Efest 2100mAh IMR 18650 3.7V LI-MN (30A), and a …
