Completed 64657 14K+ Lumens Ele II - Beamshots Added!

[sylathnie]

Phew finally complete. Running on 7 fully charged cells. Bulb doesn't pop and wow is it bright.

Beamshots later. I'm sleepy! :ironic:

Edit: The ingredients
FM Elephant 2 body with 1 extension tube
FM 2.5" throwmaster
7 Emoli 18650s from a Ryobi One+ pack
Standard mag switch core
MOSFET switch with IRF1404 from the Ryobi One+ pack (waste not!)
Osram 64657 bulb

I can run it for extended periods with no obvious side effects. It actually took me longer to make the charging rig than to make the light I think.

Here it is:

Beam Shot!
Camera set to all manual with manual shutter speeds and white balance.

Would love to hear the exact set-up you have. Sounds sweeeeet!!!!

a 250w bulb? holy snot batman! yes....we need the gory details...

and beamshots! What reflector are you running?

I am running 8 emoli 18650 cells (from Makita BL 1830 drill battery), driving the 64657 (250W) bulb. I have one with a 3" reflector and an AW soft start switch. The amount of light from that size is amazing, supposed to be about 16,000 lumen. Caveat; AW doesn't rate his switch for that power level.

How long have your run the light with AW's switch? I have the parts for this set-up, but I was afraid to send $75 (cost of switch) up in smoke. Has anybody else run their AW switch beyond the stated wattage? What are folks with Ellie 2's doing for a switch except waiting for AW's new one to come out?

This setup is just for "fun". I haven't run it more than 10 seconds at a time. I have a standard Mag switch with KIU socket I could use for long runtimes. The problem is I might have to back off to 7 batteries.

Re: Completed 64657 14K+ Lumens Ele II

Did you grind off the "ridge" inside the Ellie to get the Mag/Kiu switch to fit?

I was wondering about that too...I have an ELE II also and want to put a KIU switch in...guess I'll have to get a Dremel...

Re: Completed 64657 14K+ Lumens Ele II

Yes, I had to grind off the shoulder. I used a dremel, and one of those bits they use to cut wallboard. It looks like a drill bit, but cuts at the head and on the side. The shoulder isn't necessary on an Elephant II (my opinion). There is another shoulder inside the light that will prevent the battery pack from moving forward. That is all the switch shoulder was supposed to do anyway.

As far as heat dissipation inside the AW switch goes, as long as the total voltage is below the rated maximum, the current or amperage is more relevant than the total wattage delivered to the lamp.

A 12V 10 amp bulb for example would be far "tougher" on the switch than a 24V 5A bulb even though the power is the same.

Also, the biggest source of heat buildup in the electronics on the AW switch takes place during the switching that occurs when the light is run at reduced output using PWM. This is because the power MOSFETs have a significant amount of resistance as they are being switched off and on, thus they will heat up when used to drive a high-current load. When the light is fully on though (100% setting) there won't be as much parasitic loss because the transistor will stay in its low-resistance "on" state the whole time.

If you're too nervous about blowing an AW switch, and just want a low resistance switch that can handle high currents, I'd recommend simply installing a power mosfet on your own, and use the mag switch to drive the gate. I believe there is a tutorial thread on exactly how to do this that was posted recently.

Thanks--
This is exactly the kind of help I was looking for to make my Ellie 2 more powerful, with a bonus explanation of how AW's switch creates heat of its own. I'll follow up on this.

wheres a pic of the actual light?

Also would be nice to have something else to compare it to like a 35w HID in the beamshots.

 

[sylathnie]

Tomorrow night I will take a picture with my TK10. That is the brightest other light that I have. I added a picture of the light to the original post.

Would have to agree about the Ridge / Shoulder. I just got finished grinding the "shoulder" off in my ELE II also. Not very pretty "inside" the light anymore but nothing anyone will see anyway. Put in my 4 Emoli's...cant wait for darkness.....
