One factor to be taken into account when buying a torch, is the running cost.
Obviously mostly talking batteries here.
Purchase price plus running costs for 100 hours gives a good comparison indicator.
So, cost of a set of batteries, actual number for each torch, divided by RT gives cost / hour.
Multiply by 100, and add to purchase price gives you the 100 hour total cost.
(Not applicable for nimh use of course, unless you want to factor in PP£ of nimh batteries)
My figures, using Duracell alkalines, (@ 35p each) GBP's £££:
100 hour costs.
Fenix L1P £35.56........UFire 602 £46.47
Fenix L2P £46.25........UFire 601 £38.76
SMJLED £10.55
Dorcy 3AAA £54.96
MXDL 3AAA £51.00
etc......
Interesting that the L1P costs less than the UF602, and the L2P costs more than the UF 601 over 100 hours, by a similar factor, using alkalines !!
I didn't do RT's for Lithiums, but you get the gist.
No doubt someone could do similar calculations, using other RT graphs available on CPF, eg Chevrofreaks, for different types of batteries, and their respective RT's, specifically Lithiums.
Similarly, there has to be a crossover point (in hours) when one particular torch costs you are comparing equals the total costs of the other torch.
ie Cheaper torch but higher running costs..
Here you see the L1P become cheaper than the 602 at around 50 hours, whilst the L2P does not catch up with the 601, within 100 hours.
Other factor, the L1P is approx twice as bright as the 602, (one whole EV stop) (5,000 lux-10,000 lux) whereas the L2P is slightly less brighter than the 601, based on my own measurements.
Of course different factors come into play using nimh's.
You can pay more, up to 75p per battery in UK, obviously the costlier the battery, the costlier the 100 hour figure, and the sooner the dearer torch with longer RT's overtakes the cheaper torch, in terms of overall costs.
This occurs at approx 30 hours for the L1P 602 combination, and at approx 100 hours for the L2P 601 combination.
For Lithiums, which I suspect many CPF'ers use, the crossover point is probably less than 15 hours for the L1P 602 combination.
