The semi-conductors inside use some esoteric stuff. I don't know what material is specfically used in white LEDs but I do know that gallium, arsenic and phosphor are common. White LEDs would certainly have phosphor. The quantities are quite small though and are in the solid state unlike the mercury in CFLs. The plastic in the LEDs should be fairly innocuous. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting "I'm a designated driver on the Information Super Highway" --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
