How to mod for throw?

Flashlight Modding and DIY Parts
1

I'm planning on getting a few parts for a new build, and I want it to be extremely throwy without sacrificing on brightness.Thanks as always to anyone that responds.

A glass AR coated lens will give a few percent improvement.

Another improvement is using a precision electroformed reflector, if you can find one that fits the light.

For a $100 charge they can cut a larger one to a smaller size, but you need to know what focal length, depth, and diameter you need first.

Another way to improve the performance is using a high quality thermal compound like MX-4 between the MCPCB and flashlight body.

If you want to go all out you can use liquid metal thermal paste like thermal grizzly conductonaut.

It is a bit more dangerous though since it is conductive, you need to make sure there is no excess amount.

Thanks is for the info! Just wondering about the liquid metal paste, I only would need to put it between the area where the LED board and light body are making contact right, not on any pads right? My friend has some of that stuff so I might borrow his.

Also, I noticed on the website of the conductonaut that they say not to use it with aluminum heatsinks. My flashlight host is aluminum, so would that cause any problems?

Yeah, only between the MCPCB and the heatsink/body.

Unfortunately you will need to stick to regular thermal paste then.
MX-4 is what I recommend, NT-H1 is good too.

The Acebeam L30 is an awesome light ( I have mine for 2 months now...) but I do have big doubts that can be modded in a thrower...

The led is a XHP70.2 , so , the die is big for the reflector size .., the driver is a boost driver , probably 4.2 to 12V...For making this a thrower will need to change the led and the driver , is doable but , to buy it as a host , and add to it's value the new driver and led seems to be a little too much..! Plus the fact that the 20700 battery is not so popular ( of course , a 18650 can be used but, with a handmade spacer...) .I could be wrong as I 'm not a thrower fan...

This light is good as it is ,good spill and enough throw (over 370 meters) , and it does !

Thanks!

Yeah true. I'll probably stick with the Convoy.

I assume you are looking for a light around the size of the convoy L4? The XHP35 HI is a good choice. It can provide good throw and a bit more lumens (50% more) than domeless XPL, but only if it is driven well (~2.5A). The problem is that available single cell boost drivers aren’t really able to drive it well.

Take a look at the sofirn C8F triple reflector light. With dedomed XPL it will provide a lot of output and pretty good throw, but not as much throw as a single emitter C8.

I thought the XHP35 HI was only rated for a maximum of 1.05a?
