My Q8 with 4 of the 3V XHP-50.2’s and 4 brand new Molicel 26P 18650’s just showed me 15,000 lumens on my calibrated light box. Of course, that’s a start value and the numbers fall pretty fast from there, but the hot spot is decent, can be made better by slicing and dicing, so yeah, there it is, why not…
Perhaps someone should be trying to talk Sofirn back into those parallel extension tubes…
I travel for a living and the original BLF Q8 is a permanent fixture in bottom of my bag. Not only is it a great light, but if needed I always have several “spare” 18650s available.
I wonder if it is possible to develop a USB charger retrofit.
I have ZERO circuit design knowledge, but what about a tail pcb replacement that contained a charging circuit… unscrew tailcap to access.
It was the first wow light I looked at because of the USB charging. It’s great for a car because of the ability to recharge BUT, I decided on smaller and redundancy.
Check out the SP36…even more light then the Q8 but smaller, therefore peak will be shorter.
Started a timer upon initiating Turbo, Anduril kept the light under 111º even at up to 2 minutes, I double clicked into Turbo after checking a 2700 lumen reading at that point and the light did go to 120º at 2:34. So Anduril pretty seamlessly manages the output to control the heat, I didn’t notice it stepping down but was watching the heat on my Turnigy gun with the light tail standing pointing at the ceiling. This gave my Turnigy gun a clear shot at the head. I’ll recharge the cells and check to see the timing on step down while reading lumens in the box.
Here’s my thinking….in an emergency walk around, you want max lighting to act both as a light source and a perp blinder. 3-4 minutes does it. Then a step down to what it can on a continuous basis.
Is 120F holdable? I think it is.
Can you do that and give us the numbers? It will go a long way to the next gen justification.
I started to make a “charging cap” for my Q8. PVC end cap to screw onto the battery tube and charge all 4 cells at once, but don’t quite know how to cut threads on the inside for it to stick. No lathe or anything fancy. Was thinking press-fit, weighted, etc., but nothing jumped out at me.
The DC7 keeps getting mentioned…It a decent light? Wanting to get my first soda can and not sure where to start. Q8, D18, Meteor, DC7? Is there another thread that could help me out?
