You will look like a Cyclops.

i got the 8.4v from the pack but cant turn up the voltage on the way out as it just stays the same.

This is a voltage reduction board it would appear that the max output is 1.5 volts below the input voltage.

Is that what you need ??

no need to boost the voltage from 8.4v to 12v as the light wont turn on otherwise.

well this is the light removed from its metal case.

 

[IR772]

Do you want 12 volts from 8.4 as both devices you have shown are step down, i.e. will only reduce the voltage, not increase.

This will increase the voltage, but do not connect it with out a load on as they are easy to blow.

To be honest everything looks very bright in the last photo.

We'll I'm not a happy bunny with the new best headlight, got the bike out tonight ready for my ride put the battery pack on and no light not a thing so put another pack on and it's still the same, so it must be the light
I only got about 14 hours out of it, I hope that any of you guys that got one don't get the same problem.
I have sent a email to seller so watch this space to see if they will send me out a new one

bugger it i thought i got it the wrong way round after i paid for it lol.

the new light is more focused better lens but brightness wise there both the same.

i got some 18650 cell holders coming so can use 4 cells and then use the step down converter for that.

this is what the cree uses power wise

well that looks like a bomb lol 16.4v to 12v 4 cells on the other side.

 

[soundwave]

cheap cell 1 amp discharge to 3.1v got 814mha and lasted 49 mins 51sec.


Panasonic cell 1 amp discharge to 3.1v got 3408mah and lasted 3 hrs 57mins 55sec.

that is bang on what it should be and shows how crap the cells from china are and that proves it.

 

[soundwave]

buck converter was £3
lcd with batt cut off was £4
18650 case £70p
switch £1

total £8.70

 

[awol]

lcd with batt cut off was £4

Could you give a link for the lcd with battery cutoff?

From looking at that I think d8veh's light is brighter and smaller in size. Plus it does not have the annoying strobe function.
