I'll stick with greens-A 200mw Red is gonna look as bright as a 50mw green. So think how bright a 200mw green will be? Still, for 50 bucks it's not a bad laser. Please tell us if you like it once you've got it.

Looks promissing with those (2) 3v batteries as a power source. I just want to burn stuff, and able to see the red beam at daylight would be possible?

There is an adjustable lens on the pointer, so you can focus it to a point to burn things.

As far as a burner goes, I'd rather have a red than a green. For one thing, there is absolutely no possibility of there being any IR content in the light. Second, I woulnd't be comfortable with a laser that powerful without protecitve goggles, at which point how bright a laser looks is completely irrelevant.

In the case of a 200mW laser though, a simple refection off a specular surface like glass or a glossy surface is going to be equivalent to hitting yourself in the eye with a 10-20mW laser. I think I'll pass...

With that said, my 100mW green isn't that visible indoors w/o smoke or something like that.

what kind of 100mw green are YOU using? :thinking:
my 30mw is like a friggin lightsaber indoors at night, even visible in day time, slightly...

Right now, the air is just about 0% humidity and I have an air filter at home - there isn't any particulate matter for the light to reflect off of! That is the price of clean air (and living in the tundra-like state of MN)

Hmmmm I think your laser is over-rated my 5mw and 30mw green laser , I can see the beam on dark enviroment easily. I have an airfilter at home also and that doesn't mean the air is extra clean for particulates to reflect off.

Once you get over 100mw in green you really cant tell much of a difference in brightness since its soo freaking bright.

I have several reds ranging from 125mw to 270mw and you cant tell a brightens difference between them but burning difference is amazing. In regards to seeing the beam at night sure the 270mw beam is more visible than the 125mw red but the actual dot does not look brighter,

I hate when this happends, the laser have 12 Votes - 3 starts out of five, but no reviews.

I just ordered one - for CPF sakes of course.

Thanks! I look forward to the review.

I've had a 100mw WL Pulsar for years now. It's been fun, burns stuff, pops balloons, still works like new. It sure cost a lot more than $53 though!

I may have to get this. For some reason I still love red lasers much more than green.

EDIT: Although it probably can only take primary batteries, my experience with red lasers is that they draw very little current compared to greenies. So a pair of 3.0v Li batts should last months if not years. Another reason to love reds.

I'm a little worried about what kind of regulation this uses.. I prefer lasers to maintain a constant power over the entire battery voltage range, which requires current or PD regulation and enough voltage on top (2x3.6V Li-Pos, not 2x3V with a 317 of course).

The green DX lasers have a photo diode in the IR LD, but it would seem, they don't use it at all, even tho the "driver" circuit is complex enough to do it.

As a result, the current is directly proportional to the battery voltage. When they are full, the laser is probably getting too much current, and when they are empty, it gets too little.


I really hope this laser doesn't behave this way. If it is properly regulated, it is definatelly worth the money. If not, the driver shouldn't be too hard to replace.


But I guess we'll know soon enough.

Which laser is this? Did you ever measure it's output?

 

[MMXER]

Damn nice..... Ill wait for you guys to review it before ordering one. Still pretty cheap for the power...

Figure that it will be two to three weeks before it arrives here, so you'll need to excersize some patience & restraint until then.

thanks for making the sacrifice
cant wait to see your review. DX is like crack; Im having to leave the computer to stop myself from jumping the gun and just buying one.

It's $53, that's "free" in 200mw laser terms. I wouldn't set your expectation bar too high.

15270? 15270?!

I didn't know rcr2s existed
