Searching for best 16.8V Incan

[hblockx]

Hay guys,
I wanted to ask you which 12V halogen bulb is the brightest.
I think with my current bulb ( i dont know the name of it anymore ) it throws out over 2000lumen.
( the 12V bulb will be overdriven to 16.8V... )

Have you tried using the search function or just looking at the thread titled " Destructive Incan Bulb Tests - Updated 1/8/2010 (Newer Info Added)" just below your post?

Try this and this.

Yes i read both of them.
I bought a year ago the brightest bulb with this thread.
The problem is that the test doesnt include much 12V - 75W or 100W bulbs...


argh i have a
Osram 64623 HLX 100W
and its the brightest bulb in the test. Im just hoping there is a brighter bulb...

Does it have to be 16.8v? I assume you are either using 4 IMR cells or 14 AA's, either way if youre wanting to keep it in that voltage range then your choices are kind of limited. Me personally I would stay with the 623.

Presumably the OP is using a JimmyM regulator or AlanB drop-in and picked 16.8V to drive the 64623 at the max just before flashing the bulb.

If the OP is willing to go to a higher voltage, try the 64458 at say 20V or 21V.

But remember, it is not all just about the total lumens. A lot of them with the 64623 are "wasted" in so far as they are in such a scattered pattern, I don't consider it an ideal bulb other than its novelty effects.

I also recommend using Ictorana's superb graphs that show you comparisons in various voltage categories. Once you narrow it down to a few bulbs, it then becomes an issue of the reflector size, shape, coating and how each bulb's unique characteristics perform in them.

hmm ok think i have to be glad with my ~4000 lumen xD
i have to go to work now, thank you guys
see you later...

I'm thinking maybe a 64633,

Rated 15V, 50HR, 5600L.

The problem I see, is that, you are saying 16.8V, but are you talking about 4 li-ion cells fresh off the charger that are reading an open circuit 16.8V or are you talking about a power source that delivers 16.8V under a load?

Assuming 4 li-ion cells, you would actually get less than 5600L, but it would still work pretty decent I suppose.

Assuming 14 high current AA cells. It might theoretically push upwards of 8000 bulb lumens.

I'm talking about 14 nice AA ^^
hmm 8000Lumen would be nice xD

So, what do I win? lol

I suggest resting the pack at least till it has cooled down after a charge, maybe longer. The re-rating formulas peg the resulting bulb life at ~10 hours at 16.8V, but fresh off the charger it *could* be more than that to the bulb if the cells are really heavy hitters. Below 10 hours of re-rated life is where premature failures really start kicking in.

I have no idea how well that particular bulb mates with reflectors, so best of luck

I just have to use 1 dummy and then i have a normal bulb-lifetime
hmm think the torch-runtime is around 15min then lol

 

[mdocod]

You'll need cells that can supply 10+ amps comfortably, which means, Elite 1700s or the like, which means, runtime will be ~9 minutes by my estimate.

9 minutes isn't too bad for something that can dish out about 5000 true torch lumens and looks like a semi-normal flashlight.
