[Review] Convoy L21A with Osram KW.CULPM1.TG diode

I want to get this light! Very affordable for its capability

Welcome to BLF!
I love this light, it throws super duper far.

unfortunately, i was left on read when i sent a message to the official store on Ali for a discount. maybe im not illegible for it. sad haha

Maybe just an oversight, Simon must get an awful lot of messages. He’s always got back to me and is very helpful with advice or any problems that arise.

May also have closed early for Chinese New Year. I’m sure he’ll reply and if not send him a gentle reminder.

I suck, I know. :neutral_face:

I should review my Osram CULPM1 loaded C8+ in a NEW post (with pics!). AND I WILL… but for now I HAVE to tell the story of tonight with this phenomenal “change agent” C8+.

I was at my buddy’s hunting lodge here in Kansas tonight. I mounted the C8+ on a rifle with a better 16x scope ($500 range- DECENT scope). THIS IS USING A FET MODIFIED PRESSURE SWITCH = ZERO CURRENT LOSSES.

We went out to the side of his lake with the dam right at 1000 yards away. I dialed in the scope at full zoom… hit the FET pressure switch— OMG… we could see a friggin’ possum down by the water with this C8+ in pitch black night at 1000 yards! IF we had a gun that could shoot that far… we could have shot a coyote (with no wind, off a bench, with a custom loaded round… if we were lucky! BUT we COULD SEE IT!!!). It IS that good! :stuck_out_tongue:

Wow, wow, wow! Nobody out of six VERY experience hunters could believe it! I got three orders for these on the spot tonight.

1000 yards, you say? I should test it at that distance too :smiling_imp:

Nice review, thanks a lot! Would you be so kind to give me an advise which battery and charger I can order with this flashlight at AliExpress?

You can get a lii 100 charger and I am using LG M50T, but you can also get a Lii 50E

Thanks a lot!

Convoy’s 8A driver is actually on a timer, it has no thermal regulation. At 1 minute it triggers the gradual stepdown over the next 8.5 min, resetting to 100% repeats the process

Installed into the Convoy Z1 and it hit 79°C on its 3rd reset to High and it just carries on the same lol. I’m almost finished my review on the 8A CULPM1 version of the Z1 so I’ll definitely be mentioning it

Anyone have advice for L21a with CULPM1 vs L21a with SFT40? I understand the Osram will throw further, but it will also get much hotter, right? And won’t the SFT40 throw nearly as well as the Osram? Also, does anyone know if Simon has plans to put the KW CSLNM1.TG in the L21a? Thank you for your help! You all have helped me with my selections. My wife says I have a problem with my flashlight obsession. Yes, yes, I do. :slight_smile:

We all have that problem… :smiley:

You can ask Simon about his plans in his thread: 【convoy】SFT40 5000K back in stock (sufficient)

SFT40 is brighter, and have more spill. You can try it, I think it will be a good compromise between “I want a good thrower” and “I want to use my flashlight for something else than shining in the distance”

I definitely want more throw for this light, but if it’s too subtle of a difference, I think SFT40 is best. Thanks for the advice and I’ll check out that link.

I have both of them in exact config.

My measurements as below :

L21A CULPM1 : ~430kcd
L21B SFT-40 : ~410kcd

Meaning both are quite close for throw.

Other factors for consideration :

L21A is build like a tank, heavy and solid, much more mass, hence heat up slower than the light-weight L21B. In this case of config and owning these 2 lights, I will say L21B heat up faster than the L21A.

SFT-40 thou has more lumens than CULPM1, due to different die size, SFT-40 being bigger, has a slightly larger hotspot. At near distance, they look about same brightness to my naked eyes. At far distance, the CULPM1 looks a tad brighter but not by much.

Hi Mocarny!
First of all thank you so much for your review, it made me decide between the L21B and L21A.

However, and I deeply apologize for bumping the message up, I’m having troubles finding a place that would take paypal as payment. Aliexpress, for some particular reason, has decided to block paypal if you select shipping to argentina. It’s weird as it is, if I put an address in the states or europe, it let’s me pay with paypal no problem.

I have tried to contact both convoy lightning store and MH lightning store on aliexpress and begged them to let me do the following: Put an american address, compensate for the shipping, but ship to Argentina instead. They told me “use another payment method” which is out of my reach, I don’t want to reach out to my family when I have the balance on paypal just as available.

Now here’s where I ask, is there any way to contact Simon from Convoy Store outside aliexpress? I have no issues sending the money first, I trust the store and the good reviews and positive comments about Simon.

Hi, I use a debit card to pay from Argentina and the delivery is no problem. I also add various things to the cart and tell simon (convoy) to send them all together in the same tracking code. l21b is the best option I have one with culpm1

Hi Luis!

I’ll type both in english and spanish just in case. Do you happen to know which type of “dollar” were you charged? I’m considering using mercadopago card, but if it’s going to be more expensive than “dollar blue” I might just wait for the L21A on banggood.

As for the L21B, I saw on a review on this very site that the turbo mode doesn’t hold as long as the L21A (it was something around 40 seconds vs 4 minutes). What’s your experience with it? The L21B IS on stock on banggood.

Hola Luis!!

Que tipo de dĂłlar te cobraron con la tarjeta de credito? Tengo la tarjeta de mercadopago y tengo miedo de que se vayan al pasto con los impuestos y pase el precio del dolar blue.

Justo vi que banggood tiene la L21B, que tal mantiene el turbo? Porque en este sitio lei que el turbo (a diferencia del L21A) es de 40 segundos vs 4 minutos en el L21A.

with the province debit card 180 + 70 taxes 1 dollar-280 pesos. With the “Mercadopago” or “uala” it is not convenient. In my case, I asked Simon to change the 8amp driver for the 6amp one for the culpm1 because the increase in heat is high and the lumens are not even noticeable.

Hi :slight_smile:
Thank you for your feedback. This flashlight is really good, I like it so much.
I am sorry about your payment problems. I am using card to pay on Aliexpress, never paid with PayPal. It is strange that you cannot pay if the shipment is to Argentina…
