A decent place to start ... ?

Recommendations:

$6.99 - BLF 348

High CRI Nichia 219B emitter.
1 mode only (on-off)
Plenty bright running on common AAA battery.
(Can use 10440 Li-ion or LiFePO4 battery, but too bright IMO.)
Remarks: Elegant, stiletto-like stainless steel form. You won’t find a better made high-CRI flashlight for the price.

$19.95 - BLF A01

3 modes (L-M-H)
Similarly bright running on common AAA battery.
(10440 not recommended.)
Remarks: Rock bottom price for a 3-mode copper flashlight with high CRI Nichia emitter. If you like copper, you won’t be able to resist this one. It’s sooooo nice!

Varies - Convoy S2+
~$13 - Gearbest: http://www.gearbest.com/led-flashlights/pp_232308.html
~$19 - Simon at AliExpress: Link
3 modes (L-M-H)
Output levels vary depending on drivers and emitter bins (3x7135 = ~450 lumens, 8x7135 = ~1000 lumens).
Remarks: Must have flashlight for BLF members. Nothing fancy, just plain useful. Great beam. Best tail button made. A pleasure to use. I’d recommend that you order from the manufacturer, Simon. However, if price is more of a concern than getting the right product, then order from Gearbest.
