Where to buy T5 Lighting in Lower Mainland?

[dirtyreefer]

I keep hearing about how great T5 lighting is for heat dissipation and was wondering where you can purchase these bulbs. I know J&L sells Ice Cap ballasts, but everything else I'm not sure of.

What does T5 mean? Is it a brand or a type of HO or VHO bulb? Can someone lead me in the right direction as I am upgrading my lighting and considering using T5 instead of MH (because of the heat issues).

Any help would be greatly appreciated. Thanks
