YLP coupon for BLF

There are some really nice lights on that site. They look good, and more important, some have the mode spacing I like.

But why so many have XM-L2, aren’t those LEDs less efficient than XHP LEDs?

So many have xm-l2? Only gryphon G15 have this led.

Xml2 is 3v led, xhp series is 6v and 12v. That would require more advanced driver.

You are right not many. G15 and S15.
But G18, G180 and T05 have a XP-G2, which isn’t very efficient either.

But if the efficiency advantage is lost due to and complex driver then that’s a whole different thing. (which I know nothing about)

XР-G2 are not so bad when used in appropriate solutions, e.g. with moderate power and small smooth optics.

For example, it is impossible just to put three XHP50.2 into the Carclo optics. XHP50.2 will be too large and require larger optics for the same beam.
But if we compare the triple of XP-G2 and one XHP50.2 - suddenly they will be equal :slight_smile:

It seems to me that for the recent 3-5 years, “flashlight LEDs” have been progressing in multiple directions, in non-linear way. So usually we cannot say that “this LED is new and good, while the others are outdated”.
Now there is a really large variety of LEDs, and each new LED does not replace the previous ones, but complements them. :innocent:

The feasibility of using one or another LED actually depends on the concept, optics, and implementation of a certain flashlight.

Very informative post, thank you.

Unfortunately, they do not currently offer discounts for Panda.
You can still use general BLF coupon for 10% discount.

Thanks for the info! Too bad it got delayed so long. Hoped to get it for Christmas.

Gekko 1.0: Gekko 1.0 — Online store — YLP light

Coupon code: Gekko21 (valid until 02/23/2021)

Back in 2019 we talked about the project under working name:Stark (2*21700 8*SST20 Hi CRI 4000K)
(YLP coupon for BLF - #87 by fnksb)

(More info and pictures here (Russian): Фонарик с тачскрином... | Мастерская: INFERION)

On below video someone is using a button on the other side of the flashlight to increase/decrease brightness.

Is that space on the left side of the touchscreen to control brightness? Or is it just an indicator?

This flashlight has one of the best design I have seen all time and has a huge potential for an amazing UI if they didn’t implement any gimmicky function, with 2 buttons the UI possibility are almost endless but I for one would love to keep it simple, one button operation with the touchscreen (if its really a touchscreen) to switch around different screens showing some instead of all the numbers.

I hope they don’t make the same mistakes as with the M43, amazing design and driver engineering, but overly complicated UI.

Thanks. The cost in US dollars with the coupon code and shipping came out a lot lower than I expected based on the estimates on the website. Came out to $36 shipped rather than $36+7=$43 that I was expecting :slight_smile: :+1: . I’ve been following the mega Fonarevka thread, and it didn’t take much for me to click buy.

Is the switch the same as the Unicorn ? The size looks similar but can’t know just from the pics. I didn’t like that it was too small and had a noisy click.

Before you buy, a quick summary of what I’ve understood via Google translate:

  • Inferion had not enough time to finish the firmware, although YLP delayed the release. The current firmware mostly imitates the behavior of the Unicorn, but uses different code. So there are none of the new features like multiple moon modes, auto brightness etc.
  • Moon mode is not as moon as planned, but slightly lower than in the Unicorn.
  • There are several differences in behavior compared to the Unicorn. For example 1C from turbo switches off, 2C returns to previous level, moon is not in the main rotation but only reachable from off via 1H.
  • They discovered some bugs, but production has already started. For example, turning on the flashlight in moon mode starts in a brighter level and fades down for a few seconds.
  • Another bug is that smooth ramping is not smooth - there is noticeable jitter (because Inferion mixed left and right shift in the lower byte of the brightness variable).
  • The magnet in the tailcap is exposed. Not sure what this means regarding durability.
  • The light comes without a clip. The included silicone holder appears to be identical with the one of the Wurkkos HD20 (from the pictures).
  • The initial 900 lm are reduced to 300 lm after some minutes due to heat. Thermal regulation seems to be great, as expected from Inferion. 400 lm should be possible if temperature limit is set to 75 °C.
  • Not sure if I’ve understood this correctly, but several times they wrote that hotglue was used instead of thermal paste?!
  • The driver has external flashing pads for updates, but YLP refuses to provide update files (warranty, don’t want the firmware to be public) and doesn’t accept returns for updates (too much work).
  • They say you can’t expect more from a light that is this cheap. IMHO they should have set their goals lower if this is true.

Overall I’m pretty disappointed by this light. The hardware seems decent for the price and Inferion made a very efficient and good firmware for the Unicorn. But with this release the firmware appears to be in a beta state at most. Too many bugs, not the expected features. I planned to buy at least one, maybe two or three. Now I will wait for an improved model. If YLP would allow firmware updates this would be different.

The switch should be improved. Not so hard to press and bigger.
