Well just a curiosity,what happen on the tint if the coating instead of violet will be Rose?
That would be interest if decrease Duv without intact CRI
Simon, a couple of months ago you mentioned the 3X21A had a triple XHP70 in the works. Any time frame for pictures or release?
I have a question, which is a sincere question. What is the purpose of anti-reflective coating on our flashlight lenses? Is there some kind of glare that it eliminates ? If so is it glare on what we are lighting up or from the lens itself?
To my knowledge, it is used in order to get more light through the lens. Otherwise, some of the light would reflect back into the flashlight itself instead of going out the front. A lot of AR lenses are claimed to have ~99% transmittance. Uncoated glass is less. How much less, I’m not sure (maybe 5% less?).
Simon, do you have a timeline for the T3? Sorry if this has already been answered.

The point is the driver board, which is not a FET, but a constant current. As long as the driver board is completed, the rest of the work will be done quickly.
The manufacturer has done samples three times, but each time the samples are done, it turns out that it is very difficult to purchase chips. The supply of chips is extremely unstable this year.
I want to temporarily remove the reverse charging function.
Available now ,but there is only 4modes currently ,the 12groups driver is still in production
Hi Simon, T3 is still advertised as (pre sale) $999 listing. When will 4 mode T3 listing be advertised?
Also Simon, I would appreciate your opinion on Acupuncture?
Oh, stop needling him…
I’ll take another picture later and correct the price.
I’m confused. Are you asking me a medical question?
Not medical. Just your opinion on if you’ve had it done, or think it’s beneficial for ailments? Such as for Pain relief
Sorry, I don’t know anything about acupuncture.
I only experienced cupping cup and scrape therapy.
Have you thought about developing flashlights with dual diodes and dual batteries? For example 2*LH351D/2*14500 or 2*50XHP/2*21700 and many other options.
I have already seen many such inexpensive flashlights on Aliexpress, apparently there are factories that can make such cases from aluminum at an affordable cost.
Does L21B KW CSLNM1.TG come with a 5A 17mm 12 group driver?
I think I received one with a 6A 20mm 12 group driver.
Measured 6.5A on 100% which is a bit high for CSLNM1’s max 5A.
Hope you don’t mind, Tim, but that’s one of the best focused Osrams I’ve ever seen. Did it come from Simon that way, or did you adjust it?
It came focused like that from Convoy. I ordered the L21B KW CSLNM1.TG from Convoy store on AE a few weeks ago. :+1:
It looks like the beam throws further than my Manker MC13 White and it has a much more focused pencil beam.
I need to figure out how to use maukka calibration lights and a UNI-T 383S to measure how far it can throw. :person_facepalming:
You don’t need calibration lights to measure throw.
Just take a Lux reading from a measured distance, around 6-10m is usually good. Then enter your numbers into this - Lux to candela (cd) conversion calculator
Well, the below example is same light same distance, both lux meters are brand new. I have measured against the Extech another 6 light meters (less and more expensive) and all are measuring minimum 20% higher, nevertheless none of them measured as high as the Uni-T. And the funny thing is, that the laboratories I managed to find are proofing the lux meters, but only with standard light source (not LED) only up to 1000 lux, while the Ex-tech only has data for LED. Measuring lumens is easy with Maukka lights, but throw is confusing for me with such differences. Any ideas how can I narrow down the results?
