My quad P4 Shark C HA Mag

Nice mod Norm.
I planned to mod mine as well.
Any beamshots
And how do you set the shark driver set to 800mA?
Care to share info please?
I'm such such a novice in this area

:goodjob: Norm.

Looks very nice

Best regards

Would love some more info regarding the modification on the heatsink as I'm sorta in the planning stages of making something very similar.

Nice mod to a beautiful host I love multi-emitter lights....

great light!

do you know the runtime it actually gets?

There is a small pot on the shark board that you adjust anywhere from very low to 980mA.


When I went to mount the P4's I found that they are slightly bigger in diameter and won't fit into the little recesses, so I cut a piece of 4 mm aluminium plate with a hole saw and AAed in to the heatsink and mounted the emitters and reflectors to that, then AAed it as a complete unit. Seems to work fine the torch gets nice and warm. It also brings the reflectors up to touch the lens.

Runtime is probably about an hour (guessing)

I'm not too good at beam shots but I'll try tonight, I don't have any unmodified light as a comparison.

So, each emiter is seeing (vf) 200mA's? At that bias this is a very efficient setup and I would bet that you will be seeing about 2 hours flat runtime.

The emitters are in series so each emitter is seeing 800mA.

I didn't know the shark could handle that. Very nice.

Looks like it's worthy of a production line all by itself. It should be putting more than 600 lumens?

It makes my 2 X 18650 Mag C MOP reflector KIU socket WA1111 look slightly yellow.

That's a sweet light! Would you happen to have any beamshots? Nice pics too!

This is not a very good beam shot, I had planned to do some outside shots tonight, but it is pouring rain. My camera is only auto, the dim shot is a Electrolumens Blaster 1R runing the same P4 at about 700mA's and the other is the 4 X P4. If the weather is better tommorow night I'll try the outside shots. I'm fairly new to beam shots so I'm sorry if they are not what you were expecting.
Norm

Thanks NOrm.
I'll wait

Just tried an outside beam shot, the results are a bit disappointing, I think a lot of beam shots on CPF use a longer exposure, my camera is auto and this is the best I can do, I think the exposure time may be a bit fast, the shots don't look as dramatic as they are in real life. Same lights again the dim shot is a Electrolumens Blaster 1R runing the same P4 at about 700mA's and the other is the 4 X P4.
Norm

Thanks very much Norm.
You have tried your best.
Appriciate your effort.
What do you think of the output beam had that flashlight have 4 x McR20's ?

I have no experience with Mc20's. I would love to have used them but they would have made the light a lot more expensive, 1 McR20 cost almost the same as 4 X Ims 17. My budget for lights is limited and I'm more than happy with the light as it is. The pictures don't do it justice.
Norm

Heh, yeah 4 McR20-Seoul would be nice but are $$$. I'll be doing this soon with 20mm IMS.
