I've decided to change my Lumi light to a LED using a cutter kit. The stuff has arrived but I'm not sure how to connect it all up.
I've got a CC5W driver and a triple LED from cutter, a 13.2V battery, toggle switch and housing from Lumi.
The driver has 5 pins. batt+, batt-, grd, LED+ and LED-.
The driver has 700mA and 80mA modes, but I think I can modify it to just 700mA if I like.
Can I just connect the battery to the switch and batt - then the switch output to batt+? What's the grd pin for?
LED bit seems straight forward.
If I use a clicky switch how do I connect that up?
Sorry for all the Qs. Any help appreciated.

Looks like the battery is permanently connected to the board and so is the LEd with a switch if required on the SW terminals but has to operate at lower than battery voltage?
I'm confused as well
grd pin is presumably 'ground' for earthing the shell if powered from a mains transformer.
looks to me that you just connect the battery to the in +/- and the LED to the LED +/-
clearly I'm missing the confusing bit 🙄
If I want to switch between modes how does that work? i think I need a clicky button. How do I connect it up?
It doesn't look like it has multiple modes - it's just a constant current 700ma driver isn't it?
battery + to to 'in+', battery - to 'in-', led -/+ to LED.
You'll want to put the switch before this, in between the battery's - terminal and the 'in-' is normal I think.
I wouldn't bother connecting to the 'on/off' terminal, as it says that if you don't connect it, it will be always on, so you can just use the battery supply to switch it (or the switch you have put in).

An update incase others find this thread in the future.
I connected the toggle switch in series on the battery -ve lead. The battery +ve lead goes to batt +12v on the driver but the -ve lead (from the switch) goes on grd not the batt -12V pin. LEDs were straight fwd. LED + pin on driver to LED + on LED board and v-v.
Light level is good. Much much brighter than a 15W halogen. Spread is more than I'd like (middle beam optic) but reasonable. The LED board is not a snug fit in the Lumi housing, prob about 0.5 to 1mm clearance all round. I couldn't get the driver board in the housing due to it's length so this is mounted externally. Not ideal. I'll have to sort a weather proof housing for it. But for £30 I've got a bright long burn time light so I'm not complaining.
I opted for just 700mA level to keep control simple.
