Note: Lux measurements were taken at three inches using a Sper Scientific 1-to-20,000 lux light meter.
PRINCETON TEC BLAST The Blast packs 10,000+ lux for two hours on a pair of AAAs before fading (not bad). Another plus: It can be clipped to a baseball cap for hands-free use. $10. (800) 257-9080, www.princetontec.com (Eric Boyd / LAT)
SUREFIRE E1L With 20,000+ lux output, the E1L is bright enough for night hikes and tactical assaults. But you get only four hours on a 123A lithium battery, at $1 per battery, adding to a pricey product. $98. (800) 828-8809, www.surefire.com (Eric Boyd / LAT)
PALIGHTS SURVIVAL A 3,510-lux high beam good for 40 hours on a 9-volt battery, plus a 200-hour power-save setting and 200 hours of emergency strobe make this 2.6-ounce water-resistant mini a winner. $15. (800) 636-3288, www.palights.com (Eric Boyd / LAT)
MAGLITE SOLITAIRE This budget light features a variable beam that ranges from a dim, wide angle to a decent 2,910-lux spot good for searching a pack or tent. And its less than an ounce with AAA battery. $6. (800) 289-6241, www.maglite.com (Eric Boyd / LAT)
