Yes XP-E2

But old XP-G2 S4 2B also deserves to be in that graph cause it has just slightly lower lux performance(and sometimes certain g2s42b can have even better performance than certain black flat).

+1 for white flat. Black flat is well known for thrower led and it is easier to get what it is and also remember the name.

Another thing:
Measured the GT mini current and lumens with sanyo GA cell.
It has 792 lumens and it draws 5,5A

Limited qty of subZero switches should be available in 2-3days,spacers too, full kits 2-3days after those.

 

Still hoping ;)

 

Sorry about those promisesundecided but new osram leds came to me and I had to process bunch of orders etc., always something unexpected appears and limits my time for other stuff.

I will not predict release dates anymore, products will just appear on web,maybe that's better.

I’m sorry if this was asked before, but can the 17mm LD-4 drivers be sanded/filled to 15mm diameter and work properly?

I would ask this on PM but seeing so much work and so few time I’ll ask to you, fellow members Innocent

Please do it soon. I have been waiting since you announced the Luxeon MZ LEDs months ago. There is nothing that’s compareable to your “complete system”.

GND ring is ~1mm wide so sanding driver down to 15mm is probably too much, 16mm would be ok.

Some more checks on the BLF D80 with KW CSLNM1-TG led. (Should this led get a dedicated thread btw?)

First, I was not happy with the quite random centering that twisting a 3535 centerpiece provides, so I modded the centerpiece: with a scalpel I cut new corners 45 degrees from the original corners, fixing the 3030-sized led much better. So the flashlight has two centerpieces, one locked around the other, both sanded very thin at the underside for exact focus, now also exact centered.

With the led perfectly centered in 3 dimensions the beam was superb.

Now I measured throw again, first on the almost full 30Q (4.08V): 140 kcd (as I measured before), then let the light run for half an hour (it got hot, I estimate 70 degrees! A biscotti driver has no thermal stepdown, and a 3.9 amp flashlight produces some 15W of heat), the battery was now 3.59 V, so wel over half empty. Measured throw again and still got 125 kcd.

I did the same test with the same battery on a C8 with dedomed XP-G2 S4 2B. Started at 4.08 V with 141 kcd, and with the cell at 3.59 V I measured 90 kcd.

So the low voltage combined with the much needed current regulation of the biscotti driver makes the output and throw of a flashlight with the new Osram led more constant than a light with a direct driven S4 2B.

Plus the current is a bit lower for the same throw.

Nicely done Jos! Good thinking outside the box with the dual centering rings, very imaginative!

Thanks Dale, I’m very happy with how I got it done. But how I would like some fitting centerpieces for this led!, would make life quite a bit easier.

Thanks for the answer mate Wink Maybe I should thing reversely, then, sanding the driver till the 16mm and the extra by sanding the flashlight hole!! Thanks again!! Thumbs Up

Hi

LD-B4HV (2s – 8.4v) can use with triple XP-G2 connected in series ?

I did that here: http://budgetlightforum.com/node/63255

Now I must gather all relevant data and builds into first post of that thread.

No, 3 LEDs in series would have 9-12V forward voltage, 2S cells on the other side have 8.4V max.

Have you ever considered making 20-22mm drivers or at least stocking 17->20 and 17->22 quality spacers?

Trying to set the max power of my LD-A4. 10+ clicks enters main menu, OK, 5 fast clicks blinks and power goes down. 1 click enters current adjustment, OK, 1 blink and current goes down again. I click 7 times for 4.75A. I get 15 blinks in response. What’s up?

BTW 30 seconds of idle time was WAY too fast for me, I needed over a minute just to read the relevant section.

Correct, now you are in the setting you chose

Agro wrote:
1 click enters current adjustment,

Wrong, in the “low light” setting, 1 click = return, >= 2 clicks: Setting

You now left the setting and went back into the menu

Agro wrote:

That should not happen as you left the setting and now are in the general menu

That’s wrong, you now should be in setting 7 (whatever that is)

You can always enter again.
But in that case, read first, note the settings you want and then start configuring…

Making notes, that’s a good idea. Still, I believe that making the duration much longer would make the adjustment easier.

LED4POWER, can you tell me tint bin of the LH351D 4000k 90CRI you are selling? It says SPHWHTL3DA0GF4T0Q6, which means tint bin is T0 but there is no T0 tint bin.

Oh NVM, I see description says T6.

Isn’t 12amps too much for a triple 219B? Did it run fine? How many lumens were you making?

Forgot to let my feedback on the things received! All good and some are already in use Wink

BTW, it took me a while to figure out how to operate the driver configuration, but then it was all full speed ahead!
I’ll be getting some more soon and other stuff as well!

Thanks for you work Thumbs Up

Ordered 10x Luxeon V2 4000K 70CRI from DigiKey, excited to try these out. I think the 5000K versions will begin showing up in less than a month it seems. I’m sure LED4Power is already on top of this Smile

The original 4040 Luxeon V has one of the most evenly tinted beams of any LED I have seen so if this is remotely similar it will easily become my go to 70 CRI LED choice for 3535 footprint.
