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.

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.
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.
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.
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
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 So usually we cannot say that “this LED is new and good, while the others are outdated”.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.
