My particular TL-2 LED will widen the beam about 100% compared to the most narrow. No doughnut hole. These things (Leds) vary a LOT. Still learning.
Now, my TL-3 WILL give a doughnut hole at it's widest, WITH a big X. Go figure.
When I received my TL-3 LED, a quick comparison with my 3AA SL LED Task Light gave me the impression that the TL-3 was WHITE compared to my slightly greenish 3AA.
Ahhh. Received my replacement TL-2; that is WHITE, the TL-3 has a, hmmm, kinda yellow cast, maybe ???, it varies depending on which color you shoot them against. This stuff will drive you nuts.
Still living with both the TL's, interesting well made lights.
