Driver 3 XM-ls

Hi,

My name is Christopher and I am new to this forum but hoping for some help to find a replacement driver for a 3x CREE XM-L s.
The headlamp is a Lumonite Navigator 3000 (3000lm) so I just don’t want to throw it away if I don’t have too.
I must have switched polarity by mistake and now it is dead so similar problem as in this thread: https://budgetlightforum.com/node/67287

I tried to find an identical driver without success, can anyone help me to find supplier prefferebly in Europe. The current one has 5 modes but anything could do actually, even a new driver/LED because the lamp is quite expensive.

The Diameter of the driver is 28mm, the PCB LED is 32mm (LEDs are working fine).

I will upload photos later.

Thank you in advance.
Christopher

Welcome to BLF Chris.

The product page says that the battery is 7.4V, assuming that the LEDs are wired in parallel that means you need a buck driver with 2S input.

You need to know what sort of switch it uses, is it a mechanical switch or an electronic (momentary) switch.

Edit : looking at the pics the e-switch is integrated to the driver board making it non standard, that’s going to complicate things.

Have you tried contacting the manufacturer ? I assume it’s out of warranty but you could still ask if they’re willing to sell you a driver.

Hej och välkommen!

Yeah, that light does indeed have a rather hefty price tag. Don’t through it away, it should be possible to piggy back some other driver on to it. Which driver depends on how much room you have, and how that MCPCB is wired. Too me it looks like that MCPCB has LEDs wired in series but I can’t be sure, it would make more sense to me if they where wired in parallel. You wrote that LEDs are working fine. How much voltage does it take to light them up?

Hi/Hej!

Thank you all for your kind help and suggestions.

I sent an email to the company today asking if I could buy the driver board.

I had look at KD (thanks), great if I can use one of their “generic” ones, found this as well:KD 28mm

@Mike, it takes two batteries, it is difficult to see in the photo but if you zoom in you can see the connection on MCPCB. It is 22mm from top of driver PCB to bottom of housing, have to take into account the cable from the batteries but should be possible to fit something close to 22mm.

BTW, the driver board isn’t completely dead, it indicates it is on and there is 3v at the MCPCB.
