bigred,
I'll assume that you want a powerful light that's brighter than a G2/P60 and will run at fairly constant brightness for an hour and which can be recharged in less than 5 hours. There are a number of lights that meet these requirements including the Streamlight Stinger "family"(look into "piggyback"charger) with the possible exception of the UltraStinger which is not recommended for fast charging, the Pelican M9, the Pila G3R/GL3R and Gl4 which are dual operation lights operating from LiION rechargeables or lithium 123's, and other lights. These are all "relatively" small light-weight lights. The Pila GL4 is probably the brightest of these lights though still not in the Tigerlight's class.
The question remains; how bright a light do you want? If it must be at or near Tigerlight power then your options are more limited and both size and weight increase considerably. How big and heavy a light are you willing to carry? You can check dimensions , weight and claimed power of some well know lights here:

The Magcharger is a very bright far throwing light, though with less total output than the Tigerlight. Using 5 x 2.5 Mah Powerstream NiCADs will give you a solid 2hrs of runtime when fully conditioned. I haven't been able to find information on MagCharger fast charging, but if you carry an extra precharged bettery stick you will have about 4hrs of good runtime. Will you need to change batteries quickly? I have changed Magcharger sticks in less than 30 seconds but since the PowerStreams are much cheaper loose than custom "sticked" you'll have to allow a little longer. I mentioned that the UltraStinger is not recommended for fast charging, but an extra precharged stick will give you about a 2 hr run. Unfortunately the battery must be charged in the light. Other options include the Pelican M11, Streamlight SL-20X and SL-35X. Some of the big rechargeables can be fitted with brighter bulbs but will have reduced runtime.
I'm not aware of any commercially available LED light would meet your criteria of high brightness, long throw and excellent bright run time. Mods like the SN II are more than bright enough but have limited runtime and aren't rechargeable.
