Defintive 6X GGW-H20L Thread.

Good info here -- thanks. I've cut back my current to my new 6x to 190 mA. I'm getting 220 mW using a Jayrob lens now. This should last better than my 270 mA setup !!!

I have loads of experience with GGl 6x 405nm diode, some of which I shared here:
http://laserpointerforums.com/laser_pointer_forums_3/forum/showthread.php?t=20175

since, i had tested a few more:
" I have installed and tested probably my last ever 6x diode frromThis GGW-H20L sled.

It is indeed just like my first one (although this tme i did not send 420mA accidentally :-))
I set it only 193mA and it outputs 210mW easily through acrylic lens.
At 205mA it outputs 232mW ! I did not push it further but it certainly has potential to reach 250-260mW with 230mA if not more, just like my test unit which by the way is running just fine still.

just though i update you on this as it is interesting and reminds me of KES sleds when we were all hoping to get those mighty 20mW of 405nm out of it :-))

so,

good luck "

and, most recently 4 more.

Thee last four were most divered unfortunately. They are from this last group Buy. Here are some results

lens, acrylic with open back. All set at 216mA with Flex Drive V4

#1 178mW :-(
#2 185mW
#3 190mW but when it warms up it reaches about 205. - Not always though !
#4 206mW steady.

#1 died after 4-5min of ON time continuous. Other 3 I tested 5x5min cycles with about 1-2min OFF in between.

I will not be getting GGL sleds any more as they are becoming way too much of a gamble for the $$.

hope this helps.

best regards

Great. Thank you Milos for contributing to the thread. A lot of great into there!

I can't believe it, the 6X diode I received from Igor (handpicked) is practically identical to yours.

196ma=208 mw
208ma=238 mw (It was still rising but it freaked me out and I did not let my LPM settle down :gun: :tinfoil:)

So in theory at 196ma and with a spiffy 405nm coated lens (25-30% increase), I am looking at 260-270mw@196ma.

Hey guvnr, spare a lens for an old ex-leper?


Thanks

Brta --
I toasted my last 6x running it at 270 mA getting ~300 mW WOW -- it died in 2 days:-(
I'm running my new 6x diode at 190 mA and reading ~ 210 mW. It focuses to a pinpoint and burns stuff. This appears to be new technology diodes and some are hotter than others.

I'm looking into building a 6X... can you tell me what lens you are using?
I'm trying to determine the typical output of this diode.
It seems that these diodes are a little inconsistent, and for the price I don't know if I want to gamble.
 
Pierce --

Current info says stop at about 190 mA. With a Jayrob G1 lens assembly, you should get about 210 mW of burn. I turned a 6x up to 270 mA and got near 300 mW but for a short time.

Mike

If you want power, get an 8x Blu. Some diodes are quite HOT.

Yeah Mike there seems to be quite an enormous variance in the output, between these 6X diodes. Also Igor mentioned his disappointment before his problems began. I remember in the old days when you guys had the 6X club, most of your diodes were on the spot in terms of power curves, which led us all to believe that 6X diodes were much more consistent than the 803T diodes that were being used at the time. Which had me thinking, perhaps the reason that diodes obtained out of actual drives as opposed to sleds, are more consistent/stronger due to the fact that they passed QC. Perhaps many of these sleds are being rejected due to inefficient diode? I believe this was the case in the 16X days as well as to some extent the 803t days, when some members bought Toshiba drives of Geeks.com...?

All I know is that I need a 405nm lens this diode deserves the best.

As a side note the output of this diode, without the lens on (pure), is very horizontally balanced, I haven't seen anything like it before, it looks like a huge minus on my wall. :O (Pardon lack of a better term, I just woke up, after a pretty heavy night. :friend:)
 
I get approximately 265mW at 200mA through one of Jayrob's lenses from my 6x (GGW-H20L) diode.

I can't really say anything about if this sleds would have been destined for actual retail drives or not, but they were controversially obtained (at least initially). One of the suppliers had told someone that they were intentionally damaged to fail QC and then sold to the supplier. Some of my more recent ones also look pretty beat up, so I wouldn't be surprised if someone was still up to their old antics.

As for those 8x diodes, I would love to get one if I felt I could spare the $250-300 for the drive... I was tempted by my 15min. of 350mW from one of the SF diodes. I want more :evil:

Great to hear about your success. I'm currently running my GGW at 122ma, and get a nice beam with AR glass lens. I will either bump my DAEDAL diy up to 180ma or wait on the flexdrive to arrive. I want longevity if possible.
 
Update: I bumped current up on the DDL driver to 160ma. Beam spot looks twice its size and brightness. I put a 33 ohm resistor in series with the 10 ohm to bump the current up. Beam is a little more visible w/out smoke in a dark room. Aixis feels warm to the touch with 30 second duty cycle. I don't want to take it to 180ma until I put the heatsink/host on it.

I would not run it without a heat sink if you want longevity. I set mine to 185mA. From everything I have read it will make the diode last a very long time, and have decent power. About 170-190mW depending on he diode. Most people run them at 190-196mW with decent success.

Yeah thanks, I just bumped it up to 181ma on the DDL driver. The beam shows in a dark room OK, and with lots of smoke it is very bright violet with streaks of blue/white in the smoke. Very cool indeed. It stings the skin on my forearm after 3 seconds with the AR glass lens. At 50 feet, a white cotton target is blindingly bright. I just did a few short duty cycles. Working up a brass heatsink and aluminum host on my lathe for it now. I had a red LCC from the GGW sled going at 160ma last night, and it was beautiful until the intermittent positive terminal solder joint killed it. I'm looking for some 24/26 guage slip on leads(the ones with the holes on the tips). For me the only headache is the almost smd type soldering with 10X magnification on the LD terminals.

You have a nice diode on your hands there rkcstr. :beer:

The QC situation that you explained is quite possible, now that you mention it, it actually seems very probable. :)

How was the beam on the 350mw? :yh: I am also considering going the 8X route, was actually about to jump on it a couple of weeks ago, but some trouble took away my spare cash.

While I am still considering it though, the thing is, I am all about beam brightness, I dream to one day own a 405nm laser whose beam is as bright as a 30mw green, or at least in that area of visibility. What concerns me though, is the fact that from what I have read, many members have received low-nm 8X diodes out of the sleds, which were in the end as bright (beam wise) as a high-wl 6X. It could be just bad luck or it could be an improvement in the GaN manufacturing department making diodes more exact in terms of wavelength output?

In any case an 8X@400mw with a high wavelength is the wet dream of probably every member of the forum. (If any of you "lucky" 8X owners received a nice high-nm diode please share.) :bowdown:

quoting myself here, and repeating _ I will never risk a single $ for GGL 6x sleds.

Latest success rate is nor only %50. I had one of latest failures after about 45min of use at 216mA it turned into a 20mW defective diode with weird pattern, while still outputting mainly coherent light.


just thought i update you all.
 
this is why i love the phr 803-t I drive them at 150 ma and get from 130-160mw
with a rkcstr driver so for about 35 bucks you get a complete 125-140 mw 405 module

edit 140 is what i usually set them at not by ma but by mw -lol
