:crackup:

Between all of use in this GB... easily.

I'll count my batteries tonight. All my batteries are basically in four categories, and each set is separate.

The premium/good batteries. The "maybe" batteries I'll use if I really need them (xxxxfire and mystery). The nimh batteries, and lastly primaries.

Mostly I need batteries more for flashlights, not lasers...

does the HL445- 1000mW come with batteries or will I need to order some.

You will need some.

Just signed my FedX door sticker a few minutes ago so tomorrow they should be waiting for me when I get home.

All my rechargeable lithiums are no more than 3 months old.
Too many to list but among them there are (6) 18650b, (2)IMR 18650, (4)IMR 18350, (11) IMR16340 and (2)IMR14500.
Total of 76 ... and 1 charger (just kidding).
ALOT of non-rechargeable Lithiums also.
Multiple layers seperated and in pairs in waterproof boxes.
Bottom center gold are spacers

Nice collection, looks about like mine. I just got in some nice IMR 26650 H type cells about an hour ago that are on the grill right now.

Wow. Collectively, minus a pen 405nm and a pen 532nm, what's in my sig is what I have, and I have just enough batteries to fill these + 1 extra fully charged 18650 and 2x 16340s next to the charger. Not so much power in my collection I'm sad to say

Hey guys!!

ALL LASERS ARE SHIPPED!

I am waiting for the remaining numbers. Nevertheless they are shipped!

@ Pman kevin got you extra order he will update me about it shortly with tracking No'.

@ Awillis sorry about the wrong gift the correct gift is being shipped via postal air mail. No need for returning the geen pen.

@ Kadath kevin has a couple of concers about your videos. he wants you to move the laser a little closer to the sensor, remove the aperature stickers and show that, sow fully charged cells with a multimeter and show that, if you make that in a video and the lasers are still underspec then you can send them back to kevin. If he also finds them underspec you will be refunded 20% of the lasers costs to compensate. Also kevin wil then reship new lasers and all shipping costs are on him. If kevin tests lasers and they are on spec then you pay for shipping. (will also PM you this in case you miss it)

greetings,,

If you are talking about the "replacement" as far as extra order goes that's fine but my concern is with the second batch fedex number

That is also being worked on

That's my concern too! Looking forward to getting a 1W red

thanks: Offroad
I'm dismantling my Prius HEV for the Lithium pack... what did you say that lasers duty cycle was again:crackup:

Zraff, I received my number yesterday but the number doesn't show up in the Fedex system. Offroad checked the number with what he was given from Kevin and it was correct so he's waiting on Kevin to figure out the issue. Didn't get the rest of my order today like some did and generally there's noone home to receive the package when they would deliver so I need the number to try to get them to leave it. Offroad is waiting on Kevin for an answer on this.
In other words, I think your order hadn't been shipped yet but mine had (but the numbers not good). Offroad said the rest of the orders have shipped so you should now get a tracking number soon (one that works I hope).:scowl::

Goodness that's awesome lol. It's like challenging a play in the NFL.

That works for me!!

Well. I got the second part of my order.

I am now disappointed.

The HL405- 500mW is the only laser from the second batch I'm kind of pleased with. It starts off at ~660mW and drops steadily from there, just as I have observed from any 405nm laser.

This laser would be fine, except the LED that indicates that the circuit is complete does not work. It turn red when the laser is actually on, but does not turn green when it is simply in the "On" position, with both the plug inserted, and the key turned to on position.

The box it came in, the spine is also broken. I don't really care about the boxes, but that's 3 out of 8 total, and another straw on the came's back.

The HL650- 300mW is underspec. It peaks at 280mW very briefly, and drops fairly fast, on a slower response LPM I do not believe you would see above 250mW. The output is also rather strange... I was expecting to see a nice round dot, as we see with the simple 660 loc builds on here. Instead the dot is actually more of a line, and not focused to infinity when screwed all the way in.

There is also some splash, but nothing too extreme. I would be ok with the power too except that the beam is freaking THICK. With the power density being lower, the beam is really a let down.

Next the HL460- 100mW. Unfortunately the best peak that this laser reaches is 90mW. This is while the laser is cold, and power does drop.

This is my first single mode 445, but I'm also kind of surprised by both the beam and the dot. My expectation was for a clean round dot, this laser being sold as single mode, and for a nice thin beam. Instead the beam profile is IDENTICAL to that of a very underdriven a/m140. Maybe I'm missing something, and someone with other single mode 445/450nm lasers can chime in? Certainly it's not what I was expecting. :undecided:

The LED on this one is also not working properly. Turning red when lasing, but not turning green when in "armed/on" position.

Last, the Gift a 100mW 635nm Single Mode Laser, in an HL host.

The "good" news, it's hitting a ~180-190mW peak.

The BAD news. It's not single mode. It's the UGLY dot we're familiar with from the mitsu 300mW and 500mW. I'm posiive looking at the dot that it is an underdriven 300mW.

I'm not sure, maybe Kevin sent me the wrong laser by mistake? I was really looking forward to seeing a single mode 635nm laser. My exact words were "For the gift please ask Kevin to send the HL638 as we discussed Really can't wait to see a nice single mode 638, AND 450 (60ish)."

While at it, I retested the HL532, 300mW, from the second GB.

It started off at right around 500mW, with about 60mW of IR. At the one minute mark it was down to 380mW with about 150mW of IR, putting it well underspec.

Last I again test the HL532 150mW from the original GB. The results are consistent with what I saw with it last time. Instead of quickly hitting a peak of ~260-280mW and being somewhat erratic, and dropping slowly in power, it now takes a good minute to reach a peak of ~180mW. Unfortunately 30-40mW of that is IR. While it hasn't degraded during a 1 week period, and is kind of on spec, it's troubling that the laser could be losing power/degrading.

TL,DR; -

10 lasers in total, four overspec, and great. One with a minor issue, one with a potentially major issue (degradation), and three underspec. :undecided:

I didn't think the HL's are supposed to turn green? I guess my 520nm also is broken then
