Another “advanced” linear driver ? 
Do you mean Gekko? Yep, linear driver without PWM is one of the best solutions for this type of lights (the ones which use a 3V-LED and a 18650 battery) :+1:
Best solution for generating heat ;))
Linear drivers aren’t that bad in terms of efficiency. Depends a lot on power and battery voltage. 3V LED would require a complex buck-boost driver. Or a different LED with higher Vf and only a boost driver.
Yes, but the question is how much energy will be lost in the buck-boost converter itself…
The buck-driver will give us advantages at low and medium currents, but will lose at high and very low currents. Buck is a good solution for 3-4 LEDs and 1*18650, maybe… Not for one 3V-LED.
Boost will give advantages at very high currents with an empty battery - but with the empty battery the brightness lowers anyway…
Buck-boosts are good, but they usually require more energy on their own.
You can tell tales about best efficiency of linear driver in Fonariovka, but not here. Here we have Lume1 
LUME1 FW3X FOR FW3A 24,95$ + fw3a (35-40:money_mouth_face:. 3 LED. TRIPLE.
Unicorn 1.0 - 37$. 1 LED. These are completely different lights
And the Lume1 increases the cost significantly. For 5-10 % in efficiency.
… where you have been banned for regular flaming and hate speech… And it’s really an achievement to be banned for hating on Russian forums
As to Lume1 project, I’m actually very interested in it, and find it very promising, especially for the high-current throwers. :+1: We are looking forward to testing Lume1 in comparison with other drivers.
But this topic is about latest offers and new lights by YLP, while there are other topics to discuss driver efficiency issues.
Fonariovka became personal YLP forum , and i was banned because i don’t like “efficient” linear driver
“where you have been banned for regular flaming and hate speech”+for direct insults to forum participants ≠ don’t like “efficient” linear driver.
The Gekko looks good. The Unicorn looks good too. I’d like to get both, to show appreciation for Inferion. 
The discount offer for G180 is just about to be closed. Just a few minutes left to place the order :innocent:
Thanks for the heads up, fnksb. 
That was a really great price and I got me a Gryphon G180. 
Just ordered the 3.0r (cause it was the only dual beam in stock)
How long can I expect to wait?
Some recent reports were 3-5 months.
Usually ~3 weeks, but this summer many flights were canceled… It disrupted mail services.
Some packages which had been sent in April/May arrived only in September… Now I hope that there won’t be such long delays.
It concerns all international deliveries, not only from Russia. 
Received my G180 yesterday. Order placed on 29/08. Less than two weeks for delivery, not bad at all! Very pleased
Just missed this. I have been looking at ylp for a while now. VEry nice looking lights & specs. Keep us informed with more deals
Ordered G180 on August 29 arrived yesterday, September 14 in UK. Excellent tracking system, I knew where it was every step on the way and good communication from YLP.
This is a very well made light and I am very pleased with it.
