Foursevens Preon P1/P2 MKIII Flashlight

I've had a four sevens flashlight for about 5 years.
Gift from my youngest brother. Very very bright. The programmable settings are an interesting feature.
I liked to program mine for very low light with a medium bright on the alternate mode, when I am camping. Good for keeping night vision, but sometimes you need to light up a whole area.
When working I set for medium and super bright because in server rooms I don't care about my night vision.
Mine lost the programmability when it suffered an extended submersion on a camping trip. I don't blame 4 sevens because it was half unscrewed when it got soaked. Otherwise it would have probably survived fine.
The only con I have is that mine requires lithium cells, which are not common, and can be expensive.

CalaverasgrandeRechargeable lithium-ion cells are quite common nowadays and are well worth the investment. You can get Foursevens brand cells for $7 each on eBay or the ones recommended by Surefire, which are called K2 Energy. Very safe to use at around just $5-$6 per cell. Rechargeable hundreds of times. You can get a USB charger for as little as $10. Let me know if you need links to these items.
If you prefer primary cells (single-use, disposable), those are as little as $1 per cell at the BatteryJunction website, check their house brand called “Titanium Innovations”.
Very reliable, very affordable.
Lithium cells are always way overpriced on retail store shelves. Online, however, they’re neither uncommon nor expensive. Best of luck!
