I would say a rechargable is the way to go if you use it often.
If you us a light 5-10 minues a day 5 times a week. 7.5 minutes average a day = 37.5 mintues on average a week.
If you us a HOLA lamp with 20 mintues run time thats 1.875 times you will change the batteries a week. Lets round that up to 2 because it dims over the average time plot for an incandecent. A C3 with HOLA eats 3 CR 123's up in 20 minutes, and a SF 123 costing $1.25 a pop if bought in bulk will equal $3.75 for each set of batteries. Two sets of batteries will cost $7.50. Over the course of a year (52 weeks), thats $390 in battery costs (if you use the light 7.5 mintues a day.) Plus you have the buy the light too.
With the LOLA lamp assembly, the light should run for an hour. Thats about a set every 7-8 working days. (punch in .625 X 52 is 32.5 times you will change the batteries ina year.) Thats $121.88 or so in battery usage a year plus the cost of the light.
How small are you going for? The Tigerlight FBOP is about the size of a SF M6 (well form what I read just a hair bigger.) Its 8 inches long an the on/off/momentary switch is nar the back end of the light, takes a bit of time to get used too.
Here is a size comparison picture:
From left to right,
pack of winterfresh bubble gum, chapstick, Arc AAA LE, SL TT 1L, SF E2e, SL Scorpion, Tigerlight, and on the end a 2C Mag.
Here is a beam picture on a white wall. Well 3 seperate pictures cut and chopped together in MS paint.
From left to right,
Tigerlight, Sf E2e, and finally Scorpion. They all are on fresh batteries.
The Tigerlight does have beam artifacts due to smooth reflector but the bam in realworld usage does its job well (either lighting up dar spaces or blinding people.) The TL is also focused.
I work security at school and had my Tigerlight in usage for 2 months and then one day the light bulb blew. Tigerlight sent out a replacement at no cost and the new one seems a bit brighter. I will purchase a new bulb next month when I go back to school so i won't be caught without my TL. I do carry a Scorpion as back-up but it doesn't have nearly the wow power of the TL and the TL is guilt free lumens since I can put it in the charger after each shift and have it topped off for the next shift.
I have not read nice reviews on the SF rechargable series. they seem to have problems with their B90 battery sticks but that has since been resolved from the posts I read. The 8N seems decent, 9 series seems alright, but the 10x dominates all rechargables and offers a 60 lumen LOLA lamp but at $400+ it seems a bit excessive.
I had my search for a rechagrable a few motnhs ago and the choices were Tigerlight or Magcharger. The Maghcarger seemed like my choice at first but due to reading about WA 01160 bulbs bein a bit fragile (speculating) and needing to upgrade the battery stick and a little shorter run time also bigger size made this light undesirable. A tigerlight for $122.47 plus $8 fedEx 2 day shipping form Tactical Warehouse sealed the deal for me with the Tigerlight.
If you need something smaller (well a lot smaller) then try a Streamlight Stinger. I have not tried it but from the pictures of it and review
here it seems like a good light. It is bigger than a Mag 2AA but nowhere near the size of a Tigerlight plus it also has a fast charger option where Tigerlight only has a 10 hour slow charger.
Well anyway enough random thoughts and typing,
What do you intend to use the light for? How do you intend to carry it? What do you rate as small? Do you have a back-up?
I routinely carry a Tigerlight, SL Scorpion during work with an Arc AAA LE to back those up just in case both bulbs decide to blow (highly unlikely.)
