Spyder III Krypton Laser – Power Readings and Battery Current Draw

Is it a buck driver? (does it draw more current as the battery drains?)
 





can you please measure the beam width and divergence?
take a picture of beam, with a ruler beside the beam..

i'm suspecting something :whistle:
 
Maybe when I get some extra time I'll take some measurements with pictures...

I just tested a battery that was drained to 3.6 volts, and it measured 1945mA's current draw on high...

Whether that means 'buck' driver or not, I don't know. But that's the battery current draw from a 3.6 volt IMR battery vs 1700mA's at full charge. (Edit: 1680mA's - fresh charge) Output power the same...

He did not elaborate, but he did say no TEC. He said that if it gets too hot, the current to the diode gets regulated, depending on the temperature. I suggested maybe calling it 'TelsaCool Thermostatic Regulation’... (instead of TEC)

That's funny... they did actually listen to that suggestion on the website ;)
 
Oh yeah I see that!

It's a much more accurate description...

I wish he would share more information on the inner workings.

It's interesting about this thermostatic regulation. I would like to know more about that...
 
wow, cherry picked (maybe) unit and still only 73% of advertised power...
at first i thought you were hacked or bribed or something :P
maybe it was his plan all along :O
he knew you would write a "positive" review that you got for a few lenses
that MASTERMIND!!!

jks :P
but do update when you see some changes (output, stability, dead)

and i find it interesting how its larger than the original..
 
Good Review Jay!!!

But IMHO, I agree completely with Dave and Jerry. We need to bring our
standards up a bit and expect to get what is advertized.

For only trading a couple of 405-G-1 Lens' for this laser, you definately
got a wonderful deal...I wonder if they would still take that trade??? :D
 
Ha ha! Yeah I don't know, but yes, I got a great deal...

For sure I'll update if there is a problem with it...

As far as a 'cherry picked' unit, I kind of doubt it. The reason why, is because the first one he sent, was taken by customs. (per the tracking)

I then e-mailed the person that sent me the tracking with a co-copy to Steve. And that person was the one that handled the replacement shipment.

I guess he could have easily told them to make sure they pick out a good one.

But hey, maybe I got an under powered one?? Maybe there are some that are putting out close to 1 Watt??

Does CNI have 1 Watt modules? Just a thought...
 
How does the beam brightness compare to a 2W blue laser?

Also, how much power drop is there after 5 minutes of continuous use?

The Krypton would be about 5.37x brighter (using rhd's comparison calculator)

Edit: Apparently to have a 445 that is as bright as 750mW of 532 you need 22272.6mW

Don't forget that the calculator does not take beam diameter or divergence into account. So would take quite a bit more than even that:tinfoil:

That is true... but even with perfect beam specs on both that is a hell of a lot of power from a 445.

I wanna see that :eg:
 
I question the accuracy of that comparison calculator.

According to that calculator, a 1.9W 445nm beam is only as bright as a 133mW greenie's beam. I just compared my 1.9W blue laser to my 160mW greenie (both measured by a Kenometer Pro) and the blue beam was MUCH brighter.

The calculator is correct... and really a nice tool, but it is only a guideline imho. There is quite a bit of variation between how individuals actually perceive different wavelengths.

Try this.. go into an absolutely dark room, and shine the laser at the ceiling (non reflective ceiling obviously). See how well the room is lit up by the specle (don't look at the dot:p). I think you will find that the room will be lit up about the same by both lasers.

Also remember that the beam of a 445nm is rectangular.. so depending on what angle you look at it, you will perceive it differently.
