I haven't even talked about using it yet. Basically, it's phenomenal. I've never realised how much difference it actually makes when you paint under a daylight bulb. First of all, colours are so much more vivid. You see them as you would see them if you looked at your model on a nice, sunny day (we do get a few! Don't be so cynical...). Secondly, I'm seeing things on the model so much more clearly. I know very little about the workings of lamps - I wasn't interested in Physics - but I'm surprised by how bright this lamp actually is, and it's only 13 Watts. I haven't had a chance to paint for an extended period of time today, so I can't comment on how it affects my eyes over a long period of time, but when I did paint my eyes felt comfortable. Wait, can eyes feel comfortable? I don't know... But that's how they felt. Like they weren't straining to see, like they had to make no effort.
Negatives? None I can think of really... It emits a VERY quiet hum when you have it on, but it's nothing worse than the hum a laptop emits when running. In fact, it's rather a lot less.
Oh, and the coolest thing about it? It doesn't have an on/off switch. To turn it on you just lift it up. And that's magic as far as I'm concerned.
A great man once said, "I love lamp."
I finally see what he means.
