SKYLaser 100mW 405nm Handheld Problem

Can't really tell much from a picture, when it comes to lasers...

Shipping international, with tracking, is pricey. Without tracking, you run the risk of your package being lost.
 





Man that stinks, with his initial beam being so bright could the power to the diode have been to high? I'm sure thats a noob question but as a prospective group buy participant I'm trying to make sense of this.
 
Its obviously dead... idk why kevin is asking you to LPM that dead laser when he/they dont even LPM their lasers themselves...or at least provide any sort of proof of power chart. Tisk-Tisk Skylasers!

They do have a lpm ;) anyway i dont know why they want you to lpm it whilst it is obviously dead.

Greetings,,
 
They probably want to be 100% sure its junk. And they would probably just send you a replacement as its such a cheap laser.

Folks: I am a new member of this forum:). I just purchased a supposedly 500 mW 405 nm laser pointer from Rayfoss. Seemed to work OK for a while then reverted to the behavior indicated by Khoonda. It is bright for a few seconds, then goes to a very dim mode. If I let it rest a few minutes I can repeat the behavior over and over, bright for a few seconds, then dims. haven't tested for longer than a minute, but basically no change over that timeframe.

I didn't get any instructions on charging the 2 16340 Li cells, so I just guessed and used the charger that came with the laser for 4 hrs with each cell. Putting those back in gave a killer beam for a few seconds (I could actually see the beam emerging from the laser) then reverted to the same old activity again.

This might be a problem with current limiting laser circuitry, strange battery behavior, or perhaps a bad diode. I ordered from Rayfoss because I heard here and elsewhere they are a reputable company. I have explained my problem to them and we shall see what they do.

I do note that the laser I received (two weeks ago) looks like the same body shown in Khoonda's photos, those his laser is supposedly 100 mW.

Also, what is meant by "LEDed"?

Thanks

@uvrocks - It sounds like in your case the batteries may be at fault.

Get yourself good batteries and a good charger.

If the diode was LEDed, you would not be seeing a strong beam at all, at any point.
 
^ yeah sounds like the problem. get some IMR cells and see if that doesn't fix the problem.
 
Folks:

Yes, I was thinking it must be the batteries--can't supply the necessary current. One of the cells reads 3.8 V while the other is 1.99, which means (I suppose) that it is no longer rechargeable:(. It doesn't budge when put into the charger for 1 hr.

Can anyone suggest a reliable charger for the IMR 16340 cells? I may as well get a top of the line charger, as I want to use the laser to explore fluorescence in my large mineral collection.

Rayfoss replied and suggested getting new cells:). They will replace/repair the unit if that doesn't work, so that's good news.

Thanks a lot.
