Ok, I decided to do a little test while I walked over to pick dyl up from scouts. It’s about ten minutes there and back.
I put in my freshly charged keygos 26650, I don’t believe it was as bright as the king kong, that’s now in the charger as I’ve used the light heavily today in work.
Anyway, I let the driver ramp up to high, stuck it into my pocket and held onto the head and set out.
When I got back, the head was lukewarm to touch, its throwy enough considering reflector size, the spill takes in both sides of a British teraced street - three car widths with passing space, plus six foot of pavement and lights up the houses on both sides.
I’ll try and get a high reading on the keygos cell tomorrow, see what current its prepared to give, but you definitely want good cells to get the best out of this driver.
In use, when you power up, it goes to the last saved output level, even after cell change. A half press goes into ramping, depending on if your above or below medium (indicated in ramping mode by three slow flashes) it will either reset to minimum and ramp to high or just start ramping up. To accept your light level, turn the light off then on. Your light is now one mode till you half press again. I like it as you can set your level and stick to it. For example I’ve been using it at night as a night light if Luke wakes up. I enter ramping, it does three slow flashes, turn off then on, I have a low output, like a 3 lumen ti. This is great for not disturbing people.
At work I ramped up to medium. This is ideal under vehicles and ceiling bouncing in the little boxes I was working in, just don’t look at it when you pick it up, you see stars. :cowboy_hat_face: I inadvertently found the flashy modes today too, didn’t pay too much attention, but to leave them find the solid output, let it quickly flash three times, turn off and on after two seconds (i counted to three to be sure) back to three mode, select low, three quick flashes, off on, back to ramping.
I think this driver is a brilliant addition to any c8 sized light that will take its 10.9mm minimum height. You need something with some meat to handle the max heat generated, but it does give you many options in one light, and as said in ramping, once you have your output, you have a one output light till you need to change. No need for two buttons, nice and simple. 8)
