These are both diode powered pens. 515 and 405nm. These have different modes! there is a mode for indoors. In this mode you use the laser at 5mW. When you hold the power button it wil switch to outdoor mode. It then is 50mW. You also have a pulse mode.
If you want to try these message me. The way it works is as follows. You send me a deposit and shipping fee's. If you return it i will send back the deposit. If you want to keep it i will keep the deposit.
Could you post a picture of the [PL 532nm 1x18650] beside a [HL 532nm 1x16340] beside a [HL 520nm 2x16340] for length comparisons?
I currently own the 520nm in 2x16340 and its a bit too long as a carry type astronomy laser. I'm inclined to buy the 1x16340 version, but I have no idea what the product dimension happens to be. I'm hoping it is at least an inch shorter
Howdy, I've been trying to purchase your LP 520nm 532nm 1-50 and I keep getting the message "The link you have used to enter the PayPal system contains an incorrectly formatted item amount." when I add the trackable air mail shipping. The final displayed price is $35.9, I think that is the problem. It should be $35.90.
I went to laserbtb's webpage today and now it reads:
Thanks and Goodbye!
