I have two of these and they are amazing. Large hot spot and a VERY large corona (It lights up an entire room). It also throws better than you would expect (Not like a LEDBeam or Inova of course but you will be surprised). One word of caution :If you decide that you don't like or need the plastic tubes on three of the LED's CUT them off - Don't pull or you may pull out one of the LED's with it.
He also makes a 14 led plate that uses 10mm LED's. Much more defined hot spot but it still has a really big corona.
Diamond also makes a 5 watt maglit replacement bulb (if you can find it...). It comes with a battery tube and 3 CR1123a's so you can use it with a 2D maglite and it can also be used with a 6D maglite (if you don't mind a 19 1/2" flashlight that's as heavy as a baby
).
He seems to post items at least once a month.
There used to be a guy who was making 40 LED adapters but I kept missing him and he seems to have quit now.
Don't forget Inretech (If you have deep pockets)
