Have you been running these 06 diodes at 5 amps or 4.5 ?
Some pics would be nice, also you said you have someone who is going to get a LPM reading on the 06. That sounds great. :beer:
If the 06 is even a little bit stronger than the 44 and has even slightly less divergence with that much better price then I will risk running it with the Gball removed and a little Teflon tape on the lens threads to keep it from drawing in humid air while cooling down after use.
I think removing the Gball, pressing the diode into a module and installing a Teflon taped lens body could be done in a simple nitrogen filled isolation box.
This is the NUBM06 at 10' with just the Gball lens. I'm going to take a Gball lens that I cut the can down on and put into a threaded holder and see if that works better now that I have a module with a lot longer threading. I'm not really concerned about removing the lens. I haven't had any issues from that. Since the beam is very close to being focused to infinity just adjusting it a little should get it perfect.
I sent a diode to Flaming Pyro the guy who sells the ☓ drive hopefully he gets around to testing it. I will have my 20 LPM in less than week so I'll be able to know more about this diode.
I don't know what happened when I resized the picture but it's 3/4 of an inch at 10 feet
Unless that Gball is dirty on it's outer surface, and it could be with all that artifact/splash, then I think we should just take them off.
But the value makes it very attractive and if we Teflon tape a G2, set it and leave it alone, then it has a good chance, both my 44 and 07e that gave up kinda early were canless, but I changed lenses like underwear so that may well have added to my longevity problem.
p.s. What amp driver should I use? I have a couple used SXD's with the pot but I would rather order a V3 unless you have some drivers?
The splash isn't bad at all, I just didn't get a good picture. I don't plan on leaving the lens attached but the lens may still be usable. I try not to expose the diode unless I have to. I feel like it's bad even for enclosed diodes and I definitely don't run it with the lens off. I killed a NUBM44 like that now I'm paranoid about it happening again.
One thing I did notice is the beam from the Gball lens doesn't cross over its self. It's just a strait beam that gradually starts to spread out. I think that has something to do with the lens being so far from the emitters. I really want to get a power reading because the Gball definitely has a low amount of loss.
The SXD drivers work well, but I for personal reasons only want to buy the fixed resistance drivers, I for personal reasons don't want the little pot as I want to rule something out by process of elimination.
I will go 4.5a on the 06 until we see some LPM and foldback results.
I agree, keeping the can/Gballs on sounds like a good idea, I really miss my beautiful 07E, it was fed only 3.4 amps and had a heavy heatsink, maybe I just got one that was destine for a short life, but keeping the Gball attached sounds good if nothing else to avoid contamination.
That's an interesting looking beam, it's wide but it looks like it runs wide, a round concave/convex homemade expander could be useful, I need to find some vis AR coated lenses.
I just love the LPF community, I ordered driver from DTR and a diode from ABarnette on Friday and here they are in my mailbox Monday. I am within a 1000 miles of them both, so that helps but still, Thanks. :gj:
This diode is making some horsepower.
I regret that out of the thousands of dollars worth of electronic test equipment I own I still don't have a proper LPM, I get hard headed but now I need to know.
I only gently ran up to 4.1 amps and it was only taking 4.4 volts, I will go to 5.0 volts in a minute and I think I need to go with a 5.0 amp driver, the 4.5 I just got may not feed this hungry Gballer enough.
The beam spot is at 10 feet but the line is sharper than the burn, the line looks good actually and I will get more pics, these have some real potential and for the price WOW. I may have to Cyl pair one of these, I bet it would make a mean short-medium range leaf igniter.
I will mount it up and work with some bigger 1-2 inch wide low power lenses, I make a holder to slide on the 1.25 inch bar on the host.
The power is there, its a question of how best to use it, I would like to keep the Gball on.
I look forward to seeing LPM results because these are not weak.
I just use a 1/4 inch socket and a couple flat pieces of aluminum to press the diode in my vise, I don't use the press tool...I'm stubborn but because the Gball does not protrude the standard press tool may work?
WOW this Gball monster has not dimmed back as I have seen others do when overdriven, at 5.5a it was still getting brighter and burning a hole in my wall and it was still not at 5 volts, this is a brand new 10 amp supply and I can put a 7875 on it and run it past 5 volts and see it start to fold back, this diode has not folded back or even hit 5 volts at 5.5 amps.
NOW I am kicking myself for not having a LPM, but I need one to read 8 watts by the looks of this diode, if it's not a freak these are tough.
I am looking at the 5.5 amp beam and I don't hold the camera the same each time, I am pulled back further on the 5.5 amp pic, but the reflection on the power supply looks brighter, but the beam not as much, we really need a real LPM test, but shouldn't this diode take 5 volts worth?
I theoretically should be able to give it 5 volts and as much current as it will take at 5V Right? NO? Yes?
