Nah it dosn't really fill the whole room, I cheated and used about 1.75 sec exposure ;D ;D Now the Herc., on the other hand, fills the whole room without cheating !! I got a peak of around 63mW but i'm not sure about how well it is filtered. As I said it is a borrowed unit so it has to go back, I just HAD to see 473nm in real life though and it is spectacular. Most definately my favourite colour
EDIT: It just looked so AWESOME I just had to post it.
