What are the differences between S21D 519A 10° flat and bead? And how does it compare to M21B GT FC40?

Hi Simon,

Can you add in the details in your listing for 519A 2700K LED? Details as in sm27*M***LR9080… Thanks.

Hi Simon,

Is there any new discount working code now?

The previous one ESW5KOXA1572 is no longer working.

Thanks.

@Simon, any idea when the SFT40 5000-5700K and the new 17mm 6V boost driver will be available?

LUMINUS may not produce 5000-5700k sft40,
I got 17mm 6V 4A driver sample , But I’m not sure which LED to apply it to, what about XHP50.3 HI ?

I think XHP50.3-HI is an excellent choice. Will you stock it in multiple CCT’s? I would love to install it in a C8+ in 4000K.

I don’t know why XHP50.3 XHP70.3 has been on the market for so long, but we can only buy white light.

Simon, there are versions of the 5700K XHP50.3 and XHP70.3, with 95+ CRI and 95+ TLCI (Television Lighting Consistency Index). Are those available to you?
They are specially made for broadcast use, thus would probably be of interest for the many photography and video users of your products.

XHP70.3 HI: XHP70D-H0-B001-AD0ZK20E2

Although the official data is released, only the 6500K white light of Ra 70 can be purchased on the market.

The effect of 10deg TIR LENS is similar to that of the M21B FC40, while the concentrating effect of 10deg is slightly better.

The discount rules of the AliExpress platform have changed, I need time to think about how to set the discount.

@simon, is there a specific date for when the MAO M21B will be released?

Early August/mid-August?

Thank you for the information Simon.

I will hopefully be able to buy a MAO M21B GT-FC40 4-4.5k as soon as it releases Big Smile

Very nice, and love the 5700K B35AM option too, but why the old style C8?

Excellent.
I think I’ll stick with the S2+ in MAO and Ti, M21B in MAO, but I may have to order a C8+ in MAO for my dad. Smile

Hello Simon! I really want a S21D but with the 8A driver. When will it be available again?

There’s no replacement for displacement.

Does the S21A host include an AR window or is it uncoated?

Is there only 4-6V trigger for LVP? What about the Ni-MH? Won't it just drain them to 0V 

Can somebody test LVP with external lab power supply on the T4?

Since the boost driver needs a minimum input voltage to operate, this effectively results in a LVP for low voltage cells.

If I end up buying a T4 I may end up testing the minimum driver input voltage; but this won't happen anytime soon.

suitable for T4, not for T3

This is interesting. I have a few TIR lenses bought long ago, when I started doing DIY flashlight builds. One of these builds is an early S2+ clone I got from Fasttech, built with a host and other custom components, a very handy home flashlight for close up work because I equipped it with a TIR lens and a high CRI emitter. Always by my side over my repair table.

I still have a bunch of these Convoy S2+ compatible TIR lenses carefully stored.

So, is the T4 reflector the same size as the S2+ reflector? Or to say it otherwise, can I install an S2+ compatible TIR lens inside a Convoy T4?

 

To finish, I have a technical question. I recently discovered the Convoy T3. When at first I saw the T3 for sale at MH-lighting Store, the price was good, I had some payment bonus and frankly, couldn't resist  buying one. On top of this the seller also sent my orange 3500K 519A version almost inmediately, so how could I complain?

However, taking a closer look at this flashlight photograph in AliExpress' Convoy T3 advertisements…

 

 

… I can clearly see an overly gross R200 (0.2 Ω) sense resistor in the driver. And please notice that when I say “overly gross” here my intention is to explicitly say that the sense resitor is way too big, causing big power loss (namely in li-ion high mode) and very big voltage drop between battery and led, reducing the effective regulation window. When 1.5A go through this badly big-arse sense resistor, the voltage drop in the “driver sense resistor stage“ reachs a monstrous 0.3 V with a power loss of 0.45 W, while the output voltage is about 3+ V (what the led emitter needs, to be precise). This is rather bad driver design, because of the massive efficiency loss in the sense resistor or regulation stage, with close to 10% power loss and additional heat generation in the driver just for this reason! To put this in context, I use and store spare commercial AC led drivers at home, I know them sufficiently well and have even slightly modified a few to reduce their flickering by adding input capacitors to them. As a rule, these drivers employ a more or less fixed value of 0.225 V as sense voltage, but they are designed to output a lot higher voltages (10 - 100+ V) than a flashlight driver. For this reason, the proportional power loss of the sensing stage in them is a lot smaller, or straight out insignificant in high voltage drivers.

Now, before any comments in this regard, please bear in mind that my only goal here is mostly to make Simon aware, and advice him to raise his standards. I'd very seriously complain to the driver manufacturer of the T3 driver if it is being manufactured with such coarse and innefficient regulation stage. Good flashlight drivers can regulate with much lower sense voltages, typically in the range of 40 to 80 mV or so (the lower, the better).

 

And now, I see the T3 driver boost/buck driver being sold here by Simon in his store, using a much nicer lower value 0.05 Ω sense resistor, which means it uses a maximum of 75 mV sense voltage with a maximum power loss of 0.1125 W at 1.5 A with li-ion. This is a lot better!

 

So, what driver is gonna come with my T3 flashlight? I would like to know. Innocent Party

@barkuti

If you had bought your light a few weeks ago when the 4-mode driver was still available, you’d have gotten the innefficient driver with the big 0.2 ohm sense resistor(which is why the driver was rated at 75% efficiency).

Now that all T3s use the 13-mode driver, then you get the more sensible one, giving you 92% efficiency.

Well, thanks for clarifying BlueSwordM.
The seller confirmed my T3 is coming with a 13-groups driver. I feel relieved! Innocent

T3 4 modes Efficiency is greater than 75%.
T3 13 groups Efficiency is greater than 90%.

13groups driver costs twice as much as the 4 modes version
