What's your intended use for the light? The H502 series is nice but it is a 'mule' style light and while absolutely brilliant for tasks at arm length away (reading, cooking, repairing stuff etc) it lacks the 'punch' to see light stuff up further away. You could have a look at the Zebralight H52Fw - it should have a 'throwier' beam.
Do you specifically want an AA format light? You could take a look at the Spark ST-5, it's more of a 'T' shaped light than 'L' shaped.
Or, for a bit of variety, have a look at the Sunwayman L10A (judging just from the specs, I don't rate it as highly as the Zebralights)
