Nice. Did you find anything that interested you while browsing.



Actually on that subject of misleading click bait advertising just saw another commercial with my biggest pet peeve that makes me put the company on my black list of who not to deal with. Never buy from any company that advertises with the words "up to" as what that means is I know my target customers are so stupid they will not realize that phrase is used to make any statement that follows irreverent, non binding, misleading and downright pointless click bait hype designed to waste your time if you fall for it. I used to deal a little with the advertising at my previous employment and that always just got under my skin as it is designed to be misleading and is allowed by advertising regulations because they did not say it you just thought they did or at least it is legal to use in advertising in the two states I dealt with but that can vary from state to state.

Anyway just my off topic rant for the day. Back to work.

Another 5w 470 with a can awesome!


I'm glad I never bought one of these at $150 but someone has, there was originally 10.

This is good and a graph will be useful for making a more informed decision on current setting but what is really needed is something indicating beam quality. Also, I have no idea what the beam quality is for the N520 either. I can't in my right mind make a purchase on either of these lasers if I have no idea what comes out of the opening. Come on, DTR, this is important stuff! Please, please give some indication of beam characteristics of these two diodes with a spot comparison for a similar laser.. when you have time

Beam on the N520 is the same as the other high power 520's. N700, NDG7475, NUBM01, NUBM02. They are all probably the same product line just different bins and configurations.

The N465's spot looks to be the same size as the N450. About 2/3 that of the NUBM44.

More detailed comparisons when I get time.

Many thanks Jordan for testing such nice diodes
So N450 and N465 is the same spot size than NUBM07 (with G2)??

As usual you have brought to our community another laser diode with the specs of one experimentally deduced. It is a great service here. BTW, did I see a new B&K power supply, or have you had that for awhile.

Default Re: NEW DIODES 4.5w "N450"(nm) and 1w "N520"(nm) +...

How's the stability @ 3.5 amps in that big heat sink?

Is 3.5 amps the suggested operating current and if so what is the max short duration recommended?

Also is there any color shift when overdriven like with the 07?

Default Re: NEW DIODES 4.5w "N450"(nm) and 1w "N520"(nm) +...

These new n450 diodes are just awesome. Just finished a build with one in it, with the driver set at 4.0 amps. With a3 element lens she throws one gorgeous beam, with a nice dot also. Think I found my new favorite diode. For now anyways.

I think so, it's a heck of a nice clean beam. Just bought a new camera,

Hopefully after I learn to use it, I can get some decent bean shots. The beam does seen to be a notch tighter. (seem so to me anyways)
