i get some samples from Getian company.

12V 4A driver for L6 is in design ,too

Wow, is there a chance to see the Convoys S11 and M3 with this emitter?

By the way, can you make a long back cover for the 21700 batteries for the Convoys S11? 26650 already withdraw from the market, to buy them all the more difficult and expensive.

Comparison of the S2+ KY CSLNM1.FY
All taken on my phone, with fixed white balance to daylight.

KY CSLNM1.FY (S2+) - note the broad spectrum has some colour rendering

SST-20 2700k (S2+) - high-CRI

XP-E2 Amber (KDLITKER E6) - monochromatic

Overall impressions of the S2+ with KY CSLNM1.FY - “beautiful” golden/orange beam, with some colour rendering. Warmer than the 2700k SST-20, but not as warm as the XP-E2 Amber. 5A driver is completely over the top for this emitter, and it gets too hot within a few minutes even on 35% output, thus I’ll need to use it on 10% or 20% for night photography. This emitter would better suit a 3 or 4*7135 S2+.

While I understand there are no 2700K SST-20 tests afaik, the 3000K and 4000K high-CRI tested emitters peaked at 6 and 7A respectively, both with quite high Vf at these currents. So, 5A can be considered fine. With a full battery or close you will be driving the 2700K SST-20 close to maximum performance, but as I say still fine. Concerning the temperature thing, it basically is the same with any other emitter. Tip: you can reduce the amount of dissipated heat by charging your batteries to a slightly lower voltage (3.9 - 4V). This also enhances their lifespan.

30% is 1.5A, should be fine. The drivers also feature temperature protection anyway. If I were to have it, I wouldn't complain at all. Just learn to use it wisely and properly, and enjoy.

The post was discussing the KY CSLNM1.FY. The mention of the SST-20 was just a comparison.
Also, for my photography, I need constant brightness as otherwise I would have to change the exposure for each photo, thus I need to brightness levels that won’t trigger the temperature control.

I rushed a bit with the answer. :-)

The CSLNM1.FY is a phosphor converted emitter, this means it must behave like the CSLNM1.TG standard white flat.

Now I understand your issue, the @#$% aggressive temperature protection. The solution is here: Convoy 17/22 mm SST40 Driver temperature protection removal. It involves removing the onboard surface mount NTC resistor. Once located, push it by one side with a hot soldering iron tip until it launches. Salute once done, LoL!

I got the accessory sample for lighted switch ,
But there are two shortcomings, the tail is not waterproof, the flashlight loses its inverted function.

Will this work with the Biscotti firmware?

I just get a nail clipper and cut it, it breaks clean off.

This is great. Hope it it will be available in M21C-U or L21A.

Simon, any new info about lh351d 2700k and 3500k both cri90? Can you get them?

Also have you thought about making a 2.5A driver (like for CSLNM1.23) but with 12 groups and/or 4 modes?
This would be a good option for those who don’t want s2+ hotrods with 5A drivers.
I know you have 2.8A drivers with AMCs, but consider this suggestion too.

I have ordered LH351D 2700K,but not reach to me ,yet.
2.5A driver with 5 groups for KR CSLNM1.23 is in production , i didnt plan to produce it with 12 groups or 4modes.sorry

Hi, Simon. When do you think the 5 group CSLNM1.23 driver will be ready? It seems like I have some C8+’s to order.

I think more of the issue is that the driver’s current options are overkill for the amount of heat produced by the LED. It’s normal that at 100% there will be a step down, but not useful if 35% also steps down. Thus using a lower power drivers such as the 7135 drivers would have probably been a better choice for this emitter.

ggf31416 · 2020-11-24T22:01:41.000Z

You can ask for one with the 7135 driver. I’m not sure what are the current instructions for a custom build due to price differences (if anything the 7135 version probably would be cheaper), but you can message Simon. Or if you need more power than the 7135 driver can provide you can ask for the SST40 ‘ramping’ driver, there are two adjustable modes but the UI IMHO isn’t the best and you can set it too high by mistake. Thermal stepdown is useful for most people, but I see that it may not be desirable for light painters.

I will probably just use it on 20% output most of the time rather than getting another one made with a different driver. However I’ll do some tests on how quickly and at what output the temperature controlled brightness balances. Ramping is also not useful for light painters, stepped brightness levels are more preferable.

Hmm…I was hoping it would have 5 modes. Any chance there will be a driver with more mode options for the red?

Just receive mine today, L21A CULPM1…heheh cant wait to test it tonight

1st impression: dont under estimate of what appeared to be the brown cheap convectional box, bcos inside it, is a built-in-quality flashlight…WOW! I love the deep fins, the cut is what really impress me. Looks very complicated head design, make me stare at it for a while…

Compare head to head with FT03, obviously FT03 now look pretty much basics in design compare to L21A where head look really appealing, the glass glare purplish more than FT03, meaning L21A has a good anti-reflective coating. Although the head of L21A weight more than Ft03(balance), its function is more toward efficient thermal dissipation.
