Hi all,
Greetings from South Africa.
I recently purchased a 600mw green focusable torch style for around 80$ from a local classifieds.
It was shipped from his city to mine, which was the first vital mistake I made because of course I could not check it out. Although I am a total laser noob I certainly I knew it would be underspec but figured even 200mw at that price was not to be missed so I took it. Naughty me :tsk:
I am now sitting hanging my head with regret for being so ignorant. (Is even that the right word?!)
1) The laser is about as strong as my 100mw greenie both with fully charged batteries, which in itself is prob underspec.
2) The divergence is awful compared to my 100 green. although it is focusable the dot just does not seem to get small enough to make a decent beam. (Think the entire lens distance was miscalculated?)
3) There seems to be a lot of power lost in the fact that about 30% of the light is not focused into the dot but rather a mess around it. Tried cleaning the lens, still just as bad. I have deduced that this is an unusual amount as I have my 100mw to compare it to.
I was planning to return it immediately but I saw that it seems to be very similar (identical) looking to the Rafoss model which people say isn't TOO underspec (see pic below).
So now I have to ask - Am I making some complete idiot of a mistake or is there really nothing I can do?
Thanks in advance for any advice.
ps- i thought it looked hollow in this pic. if it does, it isn't. If you have no idea why I would think it looks hollow I apologize!
Cheerio :yh:
