in this video he says they use 1.5W red diodes but limit them to 285mW
[media]http://www.youtube.com/watch?v=l5_qJTxXlC4[/media]

"It outputs 285mW average of red light. The diode
power is 1,5W and the laser's outputting 300mW with Energizer Lithum batteries. This diode is safer than those from burners in addition it has higher power and longer lifetime."

He also says he bought it from sony

sounds a bit fishy to me
 





it might be rated at 1.5W for like a pulsed output, they don't rate there diodes in CW.

Thats my understanding.
 
There are plenty of red diodes that are 1.5W CW. I had one pass through here last year that was 6W CW @ 631nm. In a handheld like that, probably not...
 
i mean sure you can have huge red diodes like IR, but they're gonna be multimode with terrible beam specs, the guy in that video however was probably just making up bs
 
lol im prety sure thats not a 1.5 watt red diodes he's using there
it probably draws 1.5 watt total but no way its even able to output anything near 1.5 watt.

also the output would be multimode.

sony does have multiple watt red diodes.
But the would probably cost the same as a small secondhand car

the only high power red diode sony currently sels is the SLD1333YT thats a 1 watt 670-680 nm diode
 
I've also seen that video and I really don't think thats a 1.5W diode. I mean If it was actually a 1.5 diode that costs 140$ you would think he had more sense then to just hook it up directly to a couple AA's. :P

Someone asked where they can get the diode and he said he would sell one for 300 dollars.

yea i also think there is no source out there for 1.5 watt red diodes at 300 dollars.
probably more like 1500 dollars lol

Yep, that too. ;D I think its safe to say he's just talking BS to everybody.

^ that's just his camera.

I bet that that is just a LOC diode and it probably isn't 300mW.
 
Smells like bullshit.

A 1.5W diode ran off of a couple AA batts in a Minimag host?
I don't think so...
 
I was thinking the same thing about the IR... not likely though because they're not from LPF... ;D ;D
crappy camera. ::)

But a 1.5W laser might be able to run off of 3V but I doubt at full power and can't be sufficient, but I thought the typical 1.5W IR LD needs at least 3.5V :-/

And with the right focus it would be easy to light a match from that far with 150-200mW 650nm.

[coughs] BULLSHIT!! [\coughs]

The threshold would probably be around 1A...
Are you allergic to BS too?
 
Im thinking IR due to the video colour. If the colour of the diode was red, than according to the video, so is the match.

Problem is, I cant fix the video colour  after converting and playing in media player. Though when the background colours get close to what they should look like, the beam is almost white.

IR beams look white, and 300mW in 808 is no challenge to obtain. There is no way that its 1.5W even of IR, or the beam wouldnt look so tight. as Mariomaster pointed out.

I have 808nm diodes that are single mode and 400mW max, anything 500mW and over in my experiance give rectangular beams.

Then the price, ive seen 650nm 500mW CW cmounts on ebay, but the cheapest @ 1$ per mW U.S He sells them for 280?


I agree with the collective thought of 'BS' ;)

If anyone has a good editing program and wants to try, heres the avi. unedited
