Richard,

I am in the process of ordering one of your CUXM/CUXP P60 drop ins. Would it be possible to have you upgrade the 219C to the 90+ CRI version? I have the older version with the 219B LED in one of my other lights and love it. It is the reason I now have to consider strongly whether or not to purchase any light/drop-in that is not high CRI. I would be willing to pay a few dollars extra for the privilege.

Thanks,
Tim

Richard has announced his new boost drivers on his website home page. Looking forward to trying one of these! My first project will be an xhp 70.2 in a short 18350 convoy s2+ host…

Ooo, thats some awesome news. I am always in awe of what Richard creates.

Now, where is my credit card…

That’s great news! But I’m just wondering why is it so difficult to make aftermarket boost drivers. Thrunite has single cell XHP70.2 and XHP35 drivers. Acebeam has single cell quad XHP35. Even Haikelite has a driver that can run XHP35 with single cell.

One of the issues is the components and pcb being able to handle the high current. You could have 15A to 20A running through the board. Components burn up, pcb traces get fried, etc… FET’s run their high current through the driver a different way which avoids these issues. You also then need to adapt a firmware to work with it. Sometimes you have to change the driver layout to adapt to the firmware.

I’ve also heard that Lexel got NarsilM working on his boost drivers.

The race is on!

I asked the same question here: LED drivers and Accessories you want, but don’t exist and got several detailed answers.

Oh, I just remembered the most important reason. Those companies have research departments. They can pay people a salary to sit there all day to design and test prototypes and have big budgets to buy all the parts and equipment needed.

The independent guys like Richard and Lexel are just working on these things in their spare time with zero pay while trying to operate a business. So it takes them much longer. They are getting there, though. :+1:

Do you have a link to this driver?

He says it will be released in August. For right now it’s just an announcement that he’s going to be selling them.

Here you go.

Will he take preorders?

Yeah. I’d be happy to send him money just so he can get paid in advance to make the drivers.

Pre-ordering hardware is the only kind of pre-ordering I am willing, and accepting to do.

I saw the answer from the other thread.

I think Richards boost driver can do some 5A to 6V emitters and around 2A to the 12V XHP35. Should prove interesting and especially so if/when he adapts them to a ramping firmware. :smiley:

Can’t see much need for 2-3 x the power if it blows an emiteer that peaks output around 2.5A

I actually wonder why he didn’t mention 12V LEDs in his statement. Surely it’s just omitted and not just 6V? Guess we will have to wait and see!

Will it be available with an ATtiny85 option?

Andúril won’t fit on the 25. :wink:

Unknown at this time, brand new and as yet unreleased.

Yes, 6V and 12v.

Lexels are about 6A@6v and 3A@12v. I believe Richards will be about the same. They may be adjusted down a bit to make them more reliable.

I know on Lexels you can adjust the output with a resistor swap if you want to reduce the max output. I assume Richards will be the same.

For instance, with a xhp70.2 you might want 6A@6v, but with a 50.2, that’s too much current. So you would swap the resistor to give you maybe 4.5 to 5 amp at most.

We all just have to be patient.

I wonder if Richard is going to have the driver available for both clickies and e-switches.
