Thank you. Great review, I bought a couple, received yesterday and love them. Could be imagination but I put it on highest setting at 10mm from my knee for around 2 minutes and niggling pain from too much pickleball this morning went away. Will try on clients over the next few weeks to get a better idea.
I got it in. Amazing flashlight. Doing ears and now are confident to try eyes. Thanks. 30sec with diffuser
Thank you for this and all your other videos. I am ready to finally order my first panel, probably the Rex. But I'm going to grab this inexpensive torch as well because I trust your reviews.
Convoy is the best bang for your bugs in any flashlight !
add a convex lens to perfect this beauty for skin contact!
How do you do that ? How do you find a lense that fits this flashlight ?
Thanks, Andrew! I've been looking for a quality, high powered flashlight/torch for focused treatments to small areas. I see another Convoy S2+ option with 850/940 IR. Convoy S2+ with IR LED, Infrared 850nm 940nm 18650 flashlight
I realize you haven't tested this but could one presume this to be of same/similar power output? Also, is it even necessary with the high output of the 660nm model?
@gembaredllc9115 thoughts?
Where did you see the 850 option ? Could not find it.
Thank you!
Thank you for this. But what about the effective distance from the skin surface with this light?
This is super powerful. Is this kind of torch (with small area) the only one available with this power? Any other options that are larger torches? and with different wavelength?
Emisar D18 18 x SST-20 660nm would be the strongest torch with red light
I am looking for a red light therapy device that has an intensity of around 40-60mW/cm2 for certain areas like my eyes. What's the intensity of the lowest power setting on this? How far away would I need to move the torch to get 40-60mW/cm2? Thank you.
He said 100 mw
Definitely a great budget option, thanks for showing us! I had a question about the mw/cm^2... wouldn't you have to measure the surface area of the lens (pi*r^2) to find the cm^2 part? Was curious why you only used pi
I had done the math in a previous video. R is 1 cm for these devices. So 1 squared is still 1. Then 1 times pi is pi. So basically I just divide by pi.
@GembaRed LLC Ohh ok makes total sense, I have a BLF A6 flashlight that is roughly the same form factor as those s2+, measured it ~.85cm for r, so my lens is a bit smaller than yours. Its just a 4000k light but had it on my desk to compare lol. Thanks for the quick reply
@@42WallabyWaySydney yeah the S2+ lens is a bit smaller than the Thermopile diameter but it was close enough for some quick measurements and math.
I’m finding my flashlight is heating up very fast, seemingly. Is it faulty? 💜
It happens with high powered flashlights. This one is very high, which is why Andrew prefers the second highest setting thats still pretty powerful.
Awesome thanks 🎉
I CANT FIGURE OUT WHICH CHARGER TO GET? pls advise 🙏
I can't figure that out either. I thought I could use regular household batteries
@@RachelWebsterit uses a 18650 type lithium battery
both battery/chargers are no longer active.
I watched the review and was very impressed. So I purchased 3 torches from Aliexpress. Sadly all of them are faulty. Really disappointing.
Faulty how? Mine is heating up very quickly it seems… 💜
using 18650 lithium batteries?
Yea how, what battery
@@denisejackson4819Heating up is normal. Infrared produces heat. The flashlight heating up is a combination of the infrared light and the aluminium body doing its job transferring heat away from the LED. You want your flashlight to get hot if you are using it at high output. If it is not getting hot, it means the LED will get damaged from overheating.
The heat you feel from the sun is infrared, not because the sun is a ball of fire. The sun is not a ball of fire. It is a ball of light.
