Wow, 230 lumens! Do you think it will get that much from primaries? Do you run primaries on your light? And.....is there any difference between the 6P and the 6PL when adding dropin's. I suppose I should have bought the 6P instead of the 6PL if I plan on adding a different dropin.
Oh, sure you can get max brightness (230 lumens for example) with the proper emitter, driver, optic or reflector. But, keep in mind it will drain current from your batteries much quicker. That's the trade off.
The 6P has a 60 lumen incandescent P60 drop in while the 6PL has the 80 lumen Surefire LED drop in. You should get an hour from the 6P incandescent bulb at 6v but the LED is more efficient giving longer runtime. Don't be misled by the advertised 12 hr. runtime. You'll get several hours at good output followed by decreasing output over time.
I'd advise you to keep the Surefire LED since it makes an excellent task light... plenty bright for many uses.
Another good drop in to start with is the
DX 6090 which is popular among lots of CPF members including myself. Although I have recently acquired a Malkoff M60L, I do like the 6090 and for $10.00 it can't be beat. It will give you about 130 lumens for 1.5-2 hrs. runtime.
The M60L is about the same brightness but will run for 4.5-5 hrs on 6v primaries. The
M60 is really bright and one of the best Q5 drop ins available today. There are lots of choices... just depends on your wants and needs.
Just remember the trade off... more output (brightness) usually means less runtime. So make your decision with that in mind. Actually that's kind of overly simplistic.
