G2 Rechargeable

[rajanf1]

I'd like to go for the rechargeable route for one of my G2's. I have been reading around but the amount of information makes my head spin and I can't find a specific thread on a G2 host with my preferences below.

My priorities are a stock G2 host which means keeping the lexan window and practical runtimes:

1. what sort of incandescent bulbs can be run without melting the lexan window?

From LF, I assume that these bulbs are safe: HO-4, EO-4, and ES-9 as they are within the P61 lumens rating that SF says can be run in a G2. Appreciate if anybody can confirm if these are ok and if I can stretch it to a SR-9?

From Streamlight, can either the strion bulb and the TL-3 bulb in a FM adaptor work?

2. what sort of runtimes will I get from the lamps above using:

AW protected li-ions (either 2x16340 or 1x17670) in a compatible bulb above?

and, of the bulbs I mentioned above only the ES-9 has a current draw of less than 1A, will all of these lamps benefit from a LiMn chemistry? What sort of runtimes will I get with LiMn? Finally, what will happen if I use a LiMn in an ES-9.

Thanks in advance.

You read this one yet?

The compatibility chart has been updated with everything you are asking about.

The P61 is about a ~11W bulb, so anything that uses ~11W or less, should be fine with the stock lens. The HO-9 is comparable in total power consumption and heat output, that would be a good upper end limit if you don't want to be concerned with heat problems on long runs.

I suggest the IMR16340 cells for anything over ~1.2A, anything from ~0.5-1.2A and the regular protected RCR123s will have slightly better runtime... however, at 1.2A, the IMR16340 cells will have much better cycle life, so after say 100 charges, the IMR16340s will probably have better runtime than a set of RCR123s that were used for 100 charges, also, the IMR16340s will drive the same lamp slightly brighter than protected RCR123s because they have lower internal resistance, so it's all kind of a toss-up and you'll just have to make the decision based on what you think is going to be best for you.

If I had to just tell someone what to buy who was asking what you are asking, I would say get a set of IMR16340s, a ES-9 and an HO-9. Use the ES-9 when you want more runtime (should be around 37 minutes), and the HO-9 for more output with ~19 minutes runtime. This gives you a "LOLA" and "HOLA" to choose from.

Hi Eric,

Yes, I did but it did not zoom into the lexan lens but more on the body type. Also, I was looking for information about the strion but did not find it.

Anyways, your text above clarified some if not all my queries. Appreciate it.

Just FYI:

the Strion bulb draws ~1.66A and is around 6 watts. Similar to a P60.

The TL-3 bulb draws about 1.2A, and is around 9 watts, same range as a P90, SR-9, G90, etc.

hey rajanf1.
i have tried several LA's you mentioned above.
the of the 2 (e0-4 and h0-4), i prefer the h0-4. the h0-4 is very close to the presentation of the p60 LA which i like very very much. the e0-4 has a lazer like quality to it that i do not care for. with these LA's i've been using a single 17500(?) batt. this batt fits very snug in the g2 but does work. this is a great way to get guilt free p60 like performance.
i like the sr-9 LA very much too. you definately want to run that LA with 16340's (preferably AW's).... i think this is the most overlooked LA that LF makes and it renders close to the lumen output of the SF p90 LA but with less flood. i can not answer as to how it might effect the lens of the g2 because i normally run this lamp in a 6p bezel.
if i were to have to pick one LA and batt system to use in a g2 from the choices you listed above i would choose the h0-4 and a 17500 bat. if you want the output of the sr-9 and 16340 batts you could consider changing out the lens to the 6p lens IF a problem occurs.

edit: when i say "16340" i am refering to AW rcr123' and not IMR16340...
the AW batts (rcr123) would probably offer more versatility with other 123 battery flashlights.

sappyg, I assume you mean a 17670 paired with your HO-4 and EO-4. A 17500 would be too short, requiring a dummy spacer.

Thanks sappyg. I read a post of yours a week ago suggesting the SR-9. I have made a mental note of it and based on Eric's recommendation in this thread, I believe it can be safely run in a G2 stock head since it is consuming around 9-10W only...well I hope so

Hi rajanf1,

Yea, anything up to an HO-9 should theoretically be fine in a G2.

yep you're right... i should have edited that statement also. i don't have all the batt size #'s down pat yet.
