Right off hand I would say no. There are lights with WAY WAY better beam quality, such as Rayovac Industrials.
But all you have to do for the 3D and 4D is use some 1" PVC pipe cut to length, and run an extra C cell. I have a 3D with 4 C NimH, a M*g Krypton 3 cell bulb and an Acrylite lense that is real nice. Same would apply to the 4D.
For the 2D, the same trick as used in a 2C works with a little more hassle. That is use 3x123 and a 5 cell bulb. You need 1"pipe, 5/8" hose slit down one side and a spacer for the tail end. You also have to mod the end of the spring for good contact on the smaller surfaces you'll be dealing with.
Naturally, I actually USE the 3D since it runs for free.
And I'm collecting the parts to have three Superm*gs!
I also have 3 other Aluminum lights, including an S&W 3D, and a couple off brand chinese 3Ds. They respond well to extra C battery and beam correction with Writeright or Scotch Satin tape. But the M*gs are gonna get the Supermods!
