my rayfoss 200mw torch can't burn a match, is that normal?






I agree this laser is underspec.
My 200mW will light a match in +/- one second, at 3 feet away.
Red, tan, black, It doesn't matter what color the match is.
Return it and try another. You should do much better.
That's more then I can say for DX. A lot of times the one you return, was better then the replacement.:(
Good Luck!!
 
I got a similar laser from DX a long time ago. A 200mW baton style 1 x 18650 and focusable. It does not output 200mW, depending on room temperature, it produces between 80 and 100mW measured on a Laserbee I. This will let it light a dark colored match in a few seconds. Sadly, it sounds like your laser is even weaker. Rayfoss should make good on this for you, their rep is better than the DX crapshoot where you can return an underpowered laser and get a modehopper in return ...
 
well, is it the waterproof one? Because I bought the waterproof one and it wont light any matches... However it burns skin...
 
I think this laser is underspec. I have a 250mwlaser and it can't light any matches because the beam is bigger then the match. I was very disappointed at the moment, but that laser is not design to burn things up anyway.
 
yup try making it black and use goggles when trying to burn, crank it all the way one way or another dont set to infinity (small dot everywhere from your pov) and just drag the match starting from 3 inches form the front back until it lights, if it doesnt then you are so under spec it shouldnt even work
 
Do you have goggles? Because without them it's just imposible to focus it, it appears the same focused than unfocused, you just see like a green sun in front of you lol

lmao yup whole reason i told him to toss it to one side or the other and drag the match out
 
Since Rayfoss has a pretty good reputation on here as far as putting out up to spec lasers, I would first suggest looking harder at your battery and charger. You are telling us that the battery is fully charged, but how have you confirmed this?

The charger could be defective, not charging the cell fully, or the cell itself could be defective. Before making too big of a deal, I would suggest using a different 18650 that you are postive is healthy, and charging it on a charger that is confirmed as properly working (assuming you have one).

I agree with everyone else - a focusable 200mW laser should burn all kinds of things. If the problem is just a battery or charger, it's cheaper and easier to replace than it is to send the whole laser back to China and wait, wait, wait.

If you don't have an extra battery and charger, you can charge the cell you have until the charger claims complete. Pull the cell off the charger and check it's voltage under no load. It should come off the charger right around 4.20v. (If it's much lower than that, I'd be skeptical that the charger is working correctly). Write down the voltage that you observe freshly off the charger, then let the cell sit for a 2 or 3 days not installed in the laser or charger (just sitting there by itself). Check the voltage again after the few days has passed. A new, healthy cell should not lose much voltage if any. Some will still show no voltage loss at all, some may show .05v loss or so. If you are seeing a big decrease, like .10v or more, it's a good sign that the cell could be bad.

Ofcourse, if you have a more advanced charger - just set it up for 1 cycle and see how it does! :)

You could also find something that puts a 500mA load on the cell, and measure the voltage across it under load (simulating laser load). If the voltage sags (drops) much at all, the cell is probably bad. 500mA is a very light load for 18650, so you should not be having much sag at all.

too late. i returned it

by the way, i sent her the laser and faona doesn't reply ANY of my emails...

i think i was screwed by rayfoss

I hardly doubt that. When you say that you returned the laser, do you mean that you sent it to wherever it was sent without asking Faona? That would be a crazy thing to do...

no,of course no.

she replied me with some solutions (like charging batteries) and a address to return the laser (she said i could return the laser)

but that was the last email. then i wrote her more emails, and she doesn't answer anymore...


Edit: great! according to the spanish postal service, the package arrived to her! will she answer me now?

Might have something to do with the big earthquakes they have had over there this week? :undecided:
-->5.8 Magnitude 2010/04/14 01:25:15 SOUTHERN QINGHAI, CHINA
-->5.3 Magnitude 2010/04/14 00:01:17 SOUTHERN QINGHAI, CHINA
-->6.9 Magnitude 2010/04/13 23:49:38 SOUTHERN QINGHAI, CHINA

Hundreds dead in China quakes
China: 617 dead, 10,000 injured in wake of earthquake
Latest Earthquakes M5.0+ in the World - Past 7 days
I know the quakes weren't centered in Shenzhen, but sometimes Family is more important than commerce. :oops:
 
I just recently got the 200mW-flx and it cant burn a match either and i have no way to test the laser
 


Other half of video is my Rayfoss 200mW. It had 4V in it...But it charges to 4.32V. I dont own matches, Sorry :( mine was the no-IR filter...
