Wow, that sneaky 1000 number. Last week I was around 750 or so. Yikes!
Edit: Closed, winners are 18sixfifty and nofearek9!

This giveaway asks you to take two guesses on one of my recent mods.
Rules:
- You must be a BLF member on or before March 11, 2013.
- One comment per user please. Subsequent comments will be ignored.
- Your comment gives you up to three entries. One for simply posting a comment (for those who get bored reading the techie stuff, take some guesses anyway), and up to two more for correct answers to the questions below.
- The information provided below is all that will be provided in this thread. There may be other tidbits in other threads, but I will not answer questions or provide further clarification.
- Contest closes when I reach 1000 posts; about 5-7 days based on my current posts per day.
- Most important rule: Have fun!
Mod details:
Product: YinHex YH-X9 5xT6 4x18650 flashlight (basically a SolarStorm or Apex; similar finish, but not built as good)
Stock output: ~850 lm
Stock Driver: 10x7135 at 3.5 Amps, 5 modes, visible PWM
Modded Driver: "NANJG" 36x7135 at 12.6 Amps (and the 1.5A rated switch hasn't melted yet), 3 modes
Power Source: 4x Sanyo UR18650ZT, fully charged to 4.3V; driver runs in regulation during the tests (steady 12.6A).
Other mods:
- Silver thermal compound between emitter plate and head
- 16 gauge emitter wires
- Copper braid on all four battery springs
- Additional 20 gauge wires to emitters to reduce MCPCB trace resistance
- AR coated lens to replace the stock uncoated glass lens
Question 1: How many OTF lumens does the modded light generate?
Question 2: The bezel and black rubber reflector plate block a considerable number of lumens. With these items removed (leaving the reflectors and AR lens), how many OTF lumens does the modded light generate?
Answers within +-10% are considered correct and will give you an additional entry. (Edit: widened margin from 5% to 10% to improve your chances ;) )
Note: My lumen numbers may not be overly accurate, as my integrating 'box' is not very well calibrated. It has proven itself to be close in a few scenarios so far though.
- Prize #1: Silver Dollarama P60 host with and XM-L T6 3C (NW) emitter and 4x7135 1.4A NANJG 105C in an SMO P60 drop-in. Uses one unprotected 18650 or 3xAAA. Measured at 380 lm OTF. Very floody and great battery life; my kind of EDC.
- Prize #2: UltraFire SK98 XM-L T6 1x18650 Zoomie, sent straight from Fasttech (cheaper than shipping one from me)
Good luck, and thanks to everyone for making BLF so enjoyable! :)
