Ok, so I just received my 1w Spartan from DL yesterday. I've waited about a year since last august before actually making a purchase. I've read on here for quite some time, the do's and don'ts and this and that. Well here's my lil blurb.
Tested 1W 447nm with screw cap on, turn on, left for 5 seconds, turned off.
Repeated, turned on 5 seconds, turned off. Took out the Cap, aka sorta like a shutter cept a screw that blocks the hole. The laser worked fine, no changes in beam, the bar "DOT" no extra artifacts on the walls, no spray, yadda yadda.
Second, Blasted the white wall at 15ft without goggles, Mind you this WAS an accident but here's my experiance. I caught sight of the "DOT" as we call it, very hard to focus eyes on this wavelength.. but gave me a slight irritation for the night. The only thing I can relate this too, is from welding and metal fabrication over the years. With welding especially with ARC or Stick, it gives off a very intense light, in fact if you stare long enough you will get the scratchy itchy feels like fiberglass in my eyes due to the fact your basically sunburning your eyes. I've done this a few times over the years due to quick no helmet T-joints etc, catch a few arcs in the eye, but the worst I find is if you stare long enough from a distance the direct light sunburns the eye we'll say. Like someone else welding without a screen so it blocks it from everyone else walking by .. This is a VERY unpleasent feeling to the eye and its annoying as hell for days after. This laser DOT that I caught a glimpse off, was pretty damn strong from 15ft away. Mind you I got very very very minimal irritation I've come to the conclusion that you don't wanna stare at this dot for too long like a welders arc. In saying that, it didn't cause any harm, but was indeed bright as hell for the eyes to take in.
Now I do have slight eye damage from when I was younger in science class while everyone was making their stupid pinhole thingies to watch an eclipse, I just looked up and watched it and fried my eyes. So I do have some things to compare too.
So please for the love of god, if your indoors using anything of the power of this Spartan or relatively up close to it, shinning in house, barn whatever with walls.. put your goggles on first before putting batteries in .. my dumb mistakes could help one of you hopefully.
In saying that, I had to compare it at a further distance after, I went outside down the boardwalk along the pacific ocean, shined it approx 75 - 100 ft to a small bunch of rocks sticking outta the water out a ways. I don't know if its my eyes or what, but I have a really hard time even looking at it at that distance. I can't determine if the wavelength just causes strain trying to focus it or the actually damn dot was so bright that it hurts the eyes. Either way, take what you will from this, and be safe please. These things are retarded strong.
The reasoning behind my purchase? I really wanted to see if these were as as claimed to be.. so many mixed ppl saying this or that I needed a definative answer for myself.
Well, after seeing it burn threw the "Black CD case" as everyone tests this on, so far I'm about 15ft on my latest test and burned threw within 5 or so seconds. Very impressed. An attempt to light a candle was an epic fail as it basically cuts the wick right off when up close, though haven't tried at distance. I seem to have nice "line" burn marks in my white door from 15ft or so away that the CD case was up against. Again, very impressed.
Bottom line, as everyone constantly says, don't screw with these things. Unless your as stupid as me and look at solar eclipses.
Don't be me!
UPDATE!: Spartan VS black cd case @ 24.5 feet. Outcome / Laser wins after around 30 - 40 seconds, Bar/hole is about 1/2 inch long by 1/8th thick. Also to note, Avg temp roughly 20 degree's C , and the energizer 123a's are about half discharged at this point in testing.
Pic from 15ft burning, couldn't capture the whole view as I wanted to get a decent beamshot more then anything. This was taken from my Google Nexus S phone. No smoke/fog added other then prob a bit of residue of cigarette smoke possibly lingering around the room heh heh
CD Case w/distance kinda blurry.. will take a better pic
black "bar" type marks in the white door that was behind the CD case. Approx 15ft or more, will get measuring tape on this next.
Bar/Dot whatever, shot. This was after the 3 shutter/lens nut experiment/mishaps. The offset diode beam may be the reason for the diode not being destroyed. Dunno?
