I thought I had settled on the Eagletac D25a for EDC but then I saw the Eagletac D25c then that led me to the Streamlight Protac 1L-1aa. Now I can't decide which one to get. On both Eagletac lights I would use rechargeable batteries and on the Protac I would probably use a lithium AA for the extended run time but can swap to cr123 if I need it to be brighter. The only down side I can see to the Protac is the larger size. Between the Eagletac's, the D25a will have longer run time but the D25c is over twice as bright. I'm sure there are great lights I haven't even considered yet. I need help settling on an EDC light.
