I read some of these articles in the trades that say less is better when it comes to low voltage and they talk about over lighting. I disagree. I agree with unique and gambino who say you need alot of fixtures (low wattage) to achieve a better result. I think it's really hard to over light much easier to under light. everybody has a different opinion on brightness. I just think that if it is just right when your finished it's gonna be too dim later on when the lamps start to depreciate and dirt and foliage covers the lenses. I'd rather have it a bit bright to start and have it settle in to just right over time. But that's just me.
