This is an amazing cluster of ice and great light coming through. It is a little yellow for my tastes . . . but I I've used warm light on snow so I do understand where you are coming from. Really beautiful. Cindy
Nice image! I think the gas you are asking for is Sodium Vapour. Sodium Vapour lamps are energy effecient and economical, and therefore often used for road illumination. They don't have very good color spectrums - which explains the orangy light... --Olaf.dk
