This is my first attempt at writing a review so I'm gonna try my best.
On 02/13/16 I ordered a SF501B 445nm 1.5w-1.8w from sflasers.com and it arrived today.
The host is black anodized aluminum
Overall length 5.16"
Maximum diameter 1.18"
Weight 73 grams
Diode: M140/9mm 445nm
Driver: Buck driver
Lens: 3 element
Power supply: 2x 16340 batteries
Duty cycle is 60 sec On/Off
Holding the laser it feels very solid, nothing feels loose except the focus ring. Read in past posts that this is normal and is an easy fix with Teflon tape.the beam is very bright. It can be seen even in the lighted room. When focused properly it will pretty much make a hole in anything. Iv had great fun burning things. Luckily my safety glasses came first. I am really happy with my purchase. There were some snags with shipping and to be honest I was getting frustrated with the complications. The Joker stayed in constant contact with me and went out of his way to make it right. In conclusion I am a satisfied customer and would do buisness with him in the future.
I wanted to do some nighttime beam shots but wanted to make this review ASAP

As I stated before I am new to this hobby and I am trying to learn. I don't yet fully understand electronics, divergence ,etc so no need to send a negative PM about this post or if I ask for help. Trying to hold your knowledge over a beginner just makes you look foolish and could turn people away from the hobby. ( you know who you are)
