Thanx !
Is the beam as nice and artifact-free as the pic suggests?

If you're doing requests how about a beamshot outside at 10M or more?

I've been looking for a good upgrade to my L6 and the Seoul I stuck in it wasn't that exciting.

Hi Kiessling,


Yes, very smooth and hot beam ( almost perfect ). Only 1 ring seen that is very near to the outer most brim which is cause by the bezel. It's a shadow from the bezel.

Are you runing it with CR123?

As promised, an outdoor beamshot.

What is the output current and what battery setup are you using?

Hi nanotech17,


I would say that it's advisable to run the highest setting (more than 15W) on this small light on momentary use. And I did a test to find out how warm it can get and got a little surprise.

I found out at the highest output and have it run for a couple of mins, the SHARK driver thermal protection somehow kick in and shut the light off which caught me by surprise. I could not remembered reading if the SHARK driver has a specific power cut off to protect its circuit at a given unsafe temperature. And I could again turn it on after having it resting for a min or so which I think pretty fast to recover from.

Then, I immediately have it turn on again at the medium level and had it run for 40 mins. And it was just feeling warm but still comfortable to hold. I'm quite pleased as I have the entire body sink rather just the head alone. I choose to have it sink as I would want to make this light a useable light than a show piece. And also to make full use of the body finned.

Hi Icarus,


It's running on 3 x 3.7V RCR123 1000mAh unprotected cells. And while voltage dip, I record a highest current draw of about 1.68 amp on this L6 at highest setting.

Sorry, I didn't notice you used the shark with remora.
Did you measure output current (going through the led) on high?
