Convoy 5A driver killing Osram CSLNM1

That 5A driver used in the Convoy models is killing the CSLNM1, I’ve had 8 or so turn purple and/or fail because the driver is pushing 5.7A. To make matters worse the models that use a 22mm driver are being sold with the 6A driver!. I complained to Simon and his suggestion was to just use the 3A driver. This option with the 5A driver should be pulled from the store immediately. It’s been like this for over a year now, I’ve only just noticed it after I stopped using my own 4.2A driver.

The 5A driver used to operate at 4.8A until a mode group reset bug was discovered, the apparent fix ended up also increasing the current to 5.7A. Very annoying to still sell it as a 5A driver, especially for customers specifically buying it to pair with an LED at a max of 5A.

Lumens with a 4.2A driver I was installing for my customers = up to 700 lumens at 30 seconds

Result using the Convoy 5A driver (5.7A) = as low as 480 at 30 seconds with a very purple hue. I will say that a few have been okay sitting at 640 lumens, but they’re still purple.

As a solution I’ll be getting the CSLPM1 with this 5A driver or perhaps use the 3A in the S2+

Such a shame Convoy has little interest in sorting this out… this has been mentioned to Simon for over a year since it was tested by a few members of BLF, Simon’s comment to me also is that it’s okay even at 6A :frowning: it might not kill it for awhile, but it will eventually

Hm, interesting.

Thanks for putting this info out for us.

I have a Convoy C8+ with CSLNM1.

In group 1, I see no visual difference between 35% and 100%, so I like group 8 for this light.

In group 8, it maxes out at “50%”, so I know im getting all the light it can put out, without actually having to use “turbo”.

Can I assume im using less than 5.7A on this 50% mode? and therefore should have little concern about “killing” the emitter?

Yes, only at 100% is it pushing 5.7A.

On yours does the tint change when you switch to 100%?. It does on the 30+ I have in stock, some worse than others.

I like the 5.7A for other LEDs, just wish there was another slightly higher current driver than 3A.

Thanks again for the reply/info.

Sorry, I dont really have an eye for this sort of thing. Im just a simple dummy playing with some cool tools/toys.

Edit: I also havent used it on 100% since I first got it, realized there was no point, and permanenty put it in group 8.

That’s okay, no worries.

I know it is not the solution, but does it behave the same way if you are using protected cells/cells that do not reach higher amps?

Could be a good suggestion using a 5A cell, but for me selling them, it’s best I drop that setup altogether.

I liked it in the C8+ because it offered the same range at 4.2A as to what the CULPM1 gets at 8A. Djozz advised 5A was even too high to recommend selling them myself, this is why I’ve been sourcing the 4.2A elsewhere.

I kinda feel like group 8 maxing out at 50% and still being as visually bright (at least to my eyes) as 100% is the solution for people like me who already own one with this “5.7A” driver no?

Assuming that 1% is low enough for your low needs. (You lose 0.1% with group 8)

Could be if they have no experience in replacing the driver or led. The 35% mode is 2.3A, so 50% may very well be best. I’ve never tried this level

Nope. .1, 1, 10, 100

3A driver would be a better match for the LED.

Yes, but have had no issues with a warranty claim with mine at 4.2A in 3 years. You do get a significant range increase.

You can always stack 7135s on drivers or resistor mod the Convoy drivers

Wow sorry to hear what happens 'J, is this happen with the tailcap bypassed or not?. As for now i have no cslnm light yet, but thanks for the notice.

Regarding the 'mode reset bug', i've experience those with my 22mm xhp70.2 single cell driver, the red one with brass tab (6v 4,8a 5a ?). But with other same driver i experience that not.(luckily). Happens when take off the battery out, and seems random. Hope Simon fix this.

The spring doesn’t require bypassing anymore since Simon started using his high current 8A springs.

The bug happens when you don’t switch the flashlight off first before unscrewing the tail cap. Enabling mode memory seems to help. This bug was fixed over a year ago though.

So….the 3A driver achieves 371m in the S2+ which is 31m more than the 5.7A driver.

I was using my own sourced 4.2A in the C8+ measuring 963m, this 3A achieves 917m. 3A is the better choice I reckon, cooler and efficient.

Has anyone tried this 17mm 5A driver for the CSLNM1? It uses R010 and runs about 4.6 amps with a high current battery (according to customer reviews). Or is it still too much for this LED?

4.6A is perfectly fine. I was selling mine at 4.8A until the Convoy 5A was altered.

So I just came across this thread after ordering a C8+ with CSLNM1 from the Convoy store at Aliexpress. Am I to understand that I should set it up in Group 8 or 9 to protect the emitter — any group at max output of 50%? Apparently, Convoy still hasn’t resolved the issue? Thanks. And bummer! You buy a “toy” like this to enjoy it at its maximum light-saber potential, right?

You could just use a lower amp battery and it won’t stay much above 5A for very long.

When you get it just check the screws holding the mcpcb are screwed tight, they’re often loose because it’s easier to center these Osram LEDs without messing around at the factory.
