100w Need Advice

[daBear]

I have enough Mag85's and need some advice on what bulb and setup to use when making a 100w cannon using a Mag 3D host. I have recently purchased a 12AA/3D holder from 5M and that is as far as I have gotten. I know I need a 3 or 4 channel bored body, and one of AWR's heavy duty hotdrivers mounted on a KIU socket, so what bulb in the 50+ range is recommended, and where can I get a bored 3D barrel? I will be using 12 x CBP1650 cells.

Thanks in advance.

I'm using a 62138 with a hotdriver setup in my MAg100/138. I also have a couple 64610 50 watt'ers to try out.

62138 for USL style...
64625 for super white beam coupled with a regulator
64623 for direct drive and crazy big overdrive

Or you could see if you can get your hands on some of those new IRC bulbs from fellow members or online stores.

Just a few ideas off the top of my head.

Actually, with 12CBPs you're best off using a regulator and the 62138 or the 64625. The 64623 will be quite yellow with 12 cbps and the output won't be that impressive.

I use 12 IB1400's in "The Torch" with the 64623 and find it quite impressive We compared it to a USL and it was brighter though slightly warmer in color.

Hey Mac,

Mhmm it would be impressive with 12 IB1400s. 12 CBP1650s won't be as nice though, the CBP1650s are really only good for upto 8amps or so. After that, they sag too much. Whereas the IB1400s can handle 20amps or more easily iirc, which is why i advised against going 12 CBP1650s with the 623 lamp.

I've seen the beamshots of the The Torch compared against a M@g85 in The Torch's thread...very impressive stuffs!

I have two battery packs i have been using with my PIR initially set at 18.6volts. One is 15 IB 1400s and the other is 18 IB 1400s. both battery packs kick butt! I have used them with IRC 35 watt bulbs but AWR says that it runs closer to 60 or 70 watts. It will ignite newspaper and the beam is pretty awesome I have since upped the voltage to 19.0v and i will probably keep it there. I know you mentioned 100w but my 100w HD is a 62138 it also kicks butt - but the run time isnt very long using 12 CBPs 1650s.
You will need to get a finned bezel & tri-bore for sure.

Andrew posted this about a non regulated solution in OSRAM IRC:

For somebody interested in a 'poor mans' version.. 15 cells would be the bomb.. i think you can get away with 15 cells direct-drive.. what a 'gimmie'.. That'd be as much lumen as the Mag625 from 11 cells at 12.5V.. but 90 vs 118W! that is just plain awesome no matter how you break it down!

I am pretty sure that he was talking about the IB1400s because no way the GP2000s would fit in a 3D size host. I have not been able to get my hands on any GP2000s since they have been out of stock for quite some time. First chance i get i am gonna return my plain HD to upgrade it to the "625" 100w HD because Andrew says that is the one to run the IRC bulbs

Good luck,

If you're trying to build a 100W+ project on a budget, you don't absolutely need a finned head. My light is unfinned (ie. stock) and it can run for a few minutes before getting too hot to hold at the bezel/head. The tube itself can be held unto probably around 4~5 minutes on time...then it's time to turn off and cool down heh. And this light is running over 165W+ with a fresh pack before sag (no regulator here).
