Should be the first lamp on the page.
It drives very bright and pretty white from NiMh batteries. Throw in a pair of Energizer Lithiums and it's even brighter!
The hot spot from the PT20 is pretty uniform, though slightly out of round. And there are 2 large rings due to the lamp's sharply angled shoulder and a nipple at the tip. In spite of the textured reflector, the focus is pretty tight and provides lots of throw with plenty of spill to light up the immediate vicinity.
Compared to my Legend LX, the 20's hot spot is a bit wider than the LX's tightest focus and nearly as bright, but the edge cut-off is much sharper, and the spill is not as smooth (due to the above mentioned rings). The LX has a bit more throw and spill, but it weighs more, and is much more expensive to feed (2x123 Lithium vs 2AA). Oh, and the PT20's bulb doesn't fall out when you drop it. /ubbthreads/images/graemlins/tongue.gif

Here is my Yellow PT20 compared to an AA battery, the Legend LX (6V Lithium) and a crappy Mini-Mag 2AA:
And here's a quick and dirty beam shot:
Mini-Mag, PT20 (w/GH88), Legend LX
The GH88 lamp really turns the mild mannered PT20 into a fire breathing beasty that can give much more expensive lights a run for their money. Pretty impressive for a <$15 light and a $6 bulb.
