Mine didn’t work right out of the box either. After fooling with it I would get a flash the several quick flashes. I don’t know what that mode is or what. I ended up cleaning the contacts with IPA since there was plenty of grease to go around. Also, this isn’t regular Ramping IOS so it seems and wasn’t used to it’s simplified features, no batt check? But the switch isn’t super sensitive so it seems to need pretty positive inputs. I also found that it seemed pretty picky with what battery I used and button top 26650s were a must in 2 bat configuration vs flats with a magnet, for whatever reason.

I doubt Richard would be willing to custom make I driver just for this model flashlight. You would more than likely need to choose a driver that he already makes. It’s also possible that Lexel has a driver that might work. It seems unlikely it would still be able to operate on two different voltages, though. You probably need to choose either 3 Volt or 6 volt and then whatever diameter driver will fit.

Well, knowing it is using a boost driver, I don’t think Lexel still has one.

Just wait for Haikelite/Dale to respond. He will be willing to send you a driver no problem for warranty.

It may take a while though…

Why would you think there is any relation? Haikelite tends to make their own user interfaces unless they specifically say they are running such and such UI version xx.

Really? I was thinking it was a Buck. So how are the 4 leds wired? 2S2P or 4S?

Told Richard I would be willing to sacrafise one. I would prefer it work with 2 cells. He did have one that may work but wasn’t sure how lo g it would last. It was because the LED’s were in a series I believe.

4S seemingly.

2P2S would be possible. However, it would require a buck boost driver, which Haikelite hasn’t made before, and would be more expensive.

4S would be the preferred setup, since it would just require the same type of boost driver found in the SC26, beefed up a bit.

Could these leds be wired 4P and handle a FET driver without burning up?

The LED’s are on seperate mcpcb’s in a series.

So, it’s not using a single series MCPCB?

Seems a bit inefficient in terms of labor cost, and a chance of failure.

Wait!

Is there a possibility that the LEDs are simply not wired correctly?

A boost driver does not work if the input voltage is higher than the output voltage.

With 2 cells, the max battery voltage would be 8,4V, above the forward voltage of even massively overdriven 2S SST-20s.

When it first comes on with one cell, they all light up. The power switch is blue. Within 10 seconds it begins blinking red, the LED’s flash 3 or 4 times and shuts down completely. The light will not work at all with 2 cells. Nothing.

Precisely!

That means either the MCPCBs are wired incorrectly, which should not be too hard to fix. The driver would see that with one cell, the LEDs can still be lit up without any problem.

With 2 cells, the driver sees that there is a case of overvoltage, and shuts down quickly.

So doable to fix for anyone with a soldering iron.

Or the driver is faulty, which would take a lot more time.

Mine did all these things as well and didn’t work on 2 cells either. I seen the flashes and off as well as the red on the switch. If you’ve already cleaned contacts try going into other mode. Also try other batteries. I tried all different things till I got it working.
It seemed like it was in a programming mode or something.

I did get it to work with one cell for a short period of time maybe 2 times. As soon as I broke the contact/voltage ist started the same thing over. Worked once out of a weeks worth of messing with it. I did try different batteries. Got it to work once with the tail spring removed and magnet stuck to the negative side of the battery.

Never looked at it that close I will check them tomorrow afternoon.

Stuff like this is why I don’t buy Haikelite. I was really hoping they would improve their reputation on newer models. Seems not. :weary:

I have 10 or so Haikelites. This one is cheaply made, quite the dissapointment. Of all the others I have this one doesn’t even look like their work. The Q30 is the same way. Appearance is just different, just seems as though they put their name on someone else’s light. At least Banggood refunded my money. Maybe I can at least get it to work in the future.

I will get BG to contact HKL asap.

Freeme code please for haikelite sc04 thanks in advance

Im interested
