Can I ask where did you get the extra driver? I’d love to get my hands on a legit ~1.7A board.
where you can get extra driver, I would like to play with some too
I purchased the driver from Ric. I did ask that someone test the driver before it shipped.
for the review _the_!
Guess ric should post it on the web to sell it like the dry :bigsmile:
I would also add the possibility of employing U2 emitters. That alone would up the ante.
As Chicago X implies, it also seems that it is underdriven. How much could it cost to change that?
About the Center Emitter - I’m not convinced it needs it but I woudln’t be against it - and it would probably be difficult for the manufacturer to add (not to mention the lack of heat sink in the middle).
The solid copper heatsink would certainly be a plus:
- It would more easily allow the addition of a 6th emitter.
- It would allow the existing emitters to be more highly driven - either by a higher output driver - or by 2 drivers.
By the way, I would be interested in this wide-beam light if it had NW emitters as an option.
And last, but not least, I really like the look and the handle!
What is the driver size?
Hi kramer, the strobe function in the SR king is a ‘hidden’ function. When you cycle through modes normally with the electronic switch it goes like this: High -> Med/Low -> Off. You can cycle through a hundred times and you will only ever experience high and low.
However if you want strobe (which nobody does) while it is on you hold down the button for ~2 seconds and then it will switch to strobe mode, another click of the button and it returns to high, then you can cycle through as normal.
The SR king is a great utility light because of the wide spill beam, so if you’re using it to walk your pets at night it’s great (I prefer floodier lights over throwy lights when I am by myself at night as it makes it easier to pinpoint a moving target if necessary [I know, I’m paranoid.]), plus the has rated it to be a tad brighter than the Apex, and coupled with the almost non-existent thermal sag and perfect ratio of flood to throw it’s one of the lights necessary to be in your possession.
EDIT: The side switch is also excellent for one handed operation, now you can just keep a firm grip on it as long as you want.
Ric, for what it’s worth I’d suggest a total re-visit of this light.
Big heatsink behind the emitters.
Drive these out to about 2.8-3 amps each.
The reason I say this is that this light is obviously a good design, well built and has the size/build to cope with higher output.
Except the guts obviously need some serious tuning to allow that.
At the moment it’s a great lloking beefly light that doesn’t compare to some of it’s compititon (King, Dry, TJ12).
It should really be a light putting out between 2700-3300 lumens of the face.
Totally understand the dollars would skip up, but it would be worth it. You could let us know the price and we’d get numbers,
but as she is, there just isn’t enough performance difference to justify pulling the trigger. Build, looks and function do.
I had an opportunity to take quick beamshots. All of them are 2.0s, f/5.0, ISO80, WB Daylight
APEX NW:
King NW:
APEX vs. King (mouse over for King)
Apex looks like more flood than King.
Brightness looks about the same to me with the Apex looking more floody than the King. The tint in the King also looks a bit cooler.
Can someone tell me which is the sense resistor for the driver and how to calculate for the output current, I’m thinking of modding it.
Thanks
You can ask Ric for the updated driver, at 8.5amps
So when this was originally released, how high was it driven?
I’ve got the original DRY triple (non boosted Turbo, just the H/M/ L strobe settings) and I’m now looking for something a tad bit brighter and I think that this maybe it.
edit: got my settings wrong.
It’s floodier but not as bright as the DRY or the King from what I’ve read.
Im not sure if Ric formally released the 2nd driver. As per Ric the driver will output 8.5 amps
When i do get the new driver i’ll test it on my bench before soldering it up. Makes it much easier
to test the output
Im still waiting for mine hopefully soon.
I take it the handle is removable?
Yes it is. (But trust me: You don't want to remove it. It's very nice and handy!) :)
