That thing is crazy man. I gotta say the way the knob for the potentiometer came out looks great.

I really love that too, I’ve not had a pot control in years.

@maildroid

Omg thats so awesome. You make it look so easy . How is the heat ? And battery life?

Not done the heat testing yet, but I’m guessing abut 10 minutes max on high. Battery life estimate would be LED 37.5v x 3.2a= 120w Battery 29.6v x 3.1a = 91.76w 91.76/120= .76 hours run time on max.

@Agro

Have you considered DC-Fix to remove the donut?

I do have some, and it would probly work, but the loss of light and not being able to see my golden monster inside kept me from it

@CNCman

“vestureofblood” Very nice mod to your GT. And very good video of the process you experienced completing it successfully. I was curious how the throw was, and if it were possible to get it focused for throw. I have wondered why nobody has tried this type of COB led in a big flashlight.
Great job. How did you find that Driver ?? And where did you get it , Please :sunglasses:

Here is the driver. Hyperboost Driver

Taskled is really only something people know about if they are from the super old school flashlight club :face_with_monocle: If you get one make sure you press the thermal tape on to the bottom of the driver first and very well, then stick it to the heat sink, thermal path is critical. Also read the documentation as best you can, these drivers are very powerful, but also delicate.

@The_Driver

Very, cool mod VOB! :+1:

One thing though - that Cree COB LED is by far not the brightest COb LED on the market. COB LEDs really are not their specialty. Here you can find a comparison of the brightest COB LEDs on the market (in German). Citizen, the company that invented this type of LED, offers the most powerful model (rated up to 524W).

Thank you for sharing. I was not aware of that. I may give one of those a shot too. Honestly I am kinda glad I didn’t know. Posting here at BLF all that I need do for a title is write the simple truth. CXB3590 and everyone comes running because they understand. On youtube generic terms like “worlds brightest” or “worlds best” seem to play better. Now to figure out a driver solution for a 110V led :student:

@KawiBoy1428

Nicely done Matt, extremely cool idea! :+1: Love your videos too.

How hot is that TaskLED voltage boost driver getting being piggy backed with out heatsinking? Is it an issue?

There is thermal tape from it’s pcb to the factory board and this seems to be enough in my case because the driver is doing very little work. The voltage from the pack is so close to LED vf that on the lower end the driver is not even active (it goes direct drive). With a fully charged pack my low is like 400 lumens. Once the over voltage wears off I think it’s more like 120 ish.
