    Best way I know to get the Philips Ultralume or the GE SPX is from a lighting store. Chances are they will need to order them. Grainger does stock the GE bulb also I think.

    Ok... now were rollin'.
    I visited Philips' website and they don't have the Colortone 50 listed as one of their products but..... I found in their ALTO series:

    F20T12/D
    Initial Lumens 1075
    Design Lumens 960
    Kelvin Temp. 6500
    CRI 79

    Here's something else I stumbled upon regarding lighting stats and manufacturers:

    Hmm perhaps they have done away with the colortone then..

    That bulb looks good 6500k is on the blueish side of the spectrum but is just fine for plant growth.

    One thing to remember as a bulb deviates from the 5000k sunlight point. CRI will go down (which is why it doesn't always apply to growing plants) Also lumen output rating will drop a little.

    Would be worth checking against their ultralume line also. They come in 5000-6500k models but should put out more lumens. Whether the increase in price is worth it or not would be something you would have to decide.

    Hey cchang,

    I am also from Toronto, I had just checked out Home depot here myself found there selection very poor.T ry calling Rona, their is one across from the home depot on St. Clair.

    Not sure if they have the lights you are looking for but I picked up some "day light" Gro lux compact flurescents from there, they are only had them in 20 wyatt but comes with a built in reflector,made by sylvania. They also had a nice seletion of 70watt hps lights.

    I live in Caledonia and I got my lights at home hardware... It cost me fifty bucks for the ballast, a Grolux bulb and a cool white...
