Airayland T5

Hello, It has been a while since I have posted.

Does anyone have any experience with this light ?

I have a flashlight itch I need to scratch and this one (among several others) has really caught my interest.

Titanium, AA, 200lumens (more than enough for my needs) & only 73.6mm long (smaller than my Manker E11 love this light btw) for only 24 bucks with coupon code (Airayland) is pretty hard to resist.

Also considering jumping on the olight S1R band wagon (really wish they would make the AA version with the same charging capabilities. AA’s never receive any love lol).

Hope everyone’s having a great holiday season.

Thanks for any help or feedback.

One reviewer claims it has visible PWM, and it hums… I’d pass on it (for this reason alone).

I have the AA and AAA, and I am not a big fan…
Noise is very high in low and mid mode…

Yes, I have the T5.. its my review on BG for that flashlight. Big Smile

It “squee”‘s like an excited teenage girl who’s seen a new pair of shoes, on MED and LOW… Fine in HIGH obviously.

And the PWM is visible at LOW. Even I can see it, in the rain outside, and I am not sensitive to PWM. You dont need to do the “fan” or “camera” trick to see it.

But it is super small, very very light, and fits in a pocket really easily, or a clutch bag if your of the female persuasion.

I EDC mine just due to its size and weight. That and the CQG Bullet (which i have modded to XP-G3 and a new driver).

Not so bright with an Eneloop. Only measured 130 lumen out of mine on high via “bathroom sphere”, but 90 minutes of burn time. 1600mah-ish at the tail. Havent measure mah at the emitter.

14500 is nice and bright though. Still “squees” with 14500 cells.

I am hoping to do a swap of the driver like I did with the CQG Bullet, but its a very thin pill (if you can even call it that).

What is the driver diameter ?

I have not measured it as yet.

It looks to be about 12-13mm; a bit thinner than the 14500 that is in it at the moment.

The pill is not very “deep” either, which is where the problem lies for modding – the pill actually has a hole in it to fit the inductor in. Shocked

I will attempt to measure it tonight after I’ve taken the kids to the local Panto.

Okay, keep us tuned. Maybe we can find a driver that can fit and provides better modes

I have one. Nice light, good machining, good button. Yes, it has PWM noise on low and mid. And quickly gets hot on a 14500. Titanium alloy is soft and get scratched even by a stainless steel kitchen knife.

Driver is 14mm in diameter.

I’ve taken some photos with my phone too.

Will attempt to put them on here.

Wow that one would be difficult to mod. I would start by tracking down a small non-PWM driver. You may have to give up multi-modes to achieve this… at ~14mm there are fewer options out there. Although I am not a fan of it beyond the AMC7135 “smart resistor”, you could go old school resistor direct drive. By that I mean a resistor in line to throttle the current. But now you are also getting more into cell chemistry, internal resistance, discharge curves…etc.

From there mod that brass ring into a pill to house the driver. Or custom fabricate one that houses the driver and presses the MCPCB up against the reflector. Ideally the pill should also provide a thermal path and a platform for the MCPCB. Although if lower lumens from a modern LED is your goal this might not be that important. 200 Lumens from an XP-G2 will get warm, but it shouldn’t cook it. Its a very robust emitter.

Jetbeam Jet-1 MK runs CC with <1.5V
The driver might have the same diameter
I could measure it

I thought the cqg bullet would be difficult to mod..

But it turned out there was a better driver than the factory one out there that fit with a little sanding, and if the pill was turned upside down.

So it gives be hope for this one too.

You might be able to salvage parts from a thorfire TG06.

Tom E has some thorfire TG06 mods in this thread…

Cool thing about tailcap clicky designs is even the most seemingly impossible mods… are actually very possible.

Also if you go with a mule design, and push the LED forward closer to the glass that would probably open up some more possibilities.

I have to correct myself… salvaging a thorfire TG06 driver would gain you nothing, it too has visible PWM in low modes. Although I do not think it has a history of inductor whine and noises.

I have one incoming as a mod host, but thats for another thread. Smile

I have a tg06. It’s a 16mm driver.. Could maybe be sanded down.

This is the size of the t5 compared to the utorch ut01.

Oh wow that is dinky. I can’t seem to find anything smaller than 17mm. DX and intl-outdoor (IIRC) used to sell smaller driver boards years ago. I think a lot of them were double stacked boards though. Some sanding is the only option outside of salvaging a driver from another light.

If NiMH regulation is still your goal you have limited options. I have no first hand experience with any of these, I am willing to bet most have visible PWM. Like the TG06 and your OEM driver.

Craig has this low voltage driver here:

If the noise and inductor whine is whats bothering you, you could try potting it… (Sorry I don’t know the proper word for it.) Potting is a term guitar players use for submersing guitar pickup coils in paraffin wax to mute feedback and noise from loose coil windings.

Here’s some options that are smaller than 17mm….

I like this one… 16mm, but it looks like it can be sanded WAY down. No disco, and the right mode sequence… L-M-H. Not sure how bad the PWM is.

This one opens up the option of 14500 cells too. Although it has a strobe… yuk.
