I found the colour tone 75 at brite-lite.com, they have an outlet here in Calgary. They quoted me 9.00 to 9.50 per 48" T12 bulb, but I would have to order a case (30?) of them. This would be a great bulb to over drive.

This is the place that I buy my end caps, cords, timers, and E-ballasts for a few dollars cheaper than Home Depot.

In looking around for inexpensive lighting I have found the lumens decrease with the higher CRI bulbs. So there is some trade off between intensity and colour.

The GE Ultra Daylights (blue & white packaging) that I bought at Canadian Tire have a initial lumen of 3050 and CRI 75. GE also sells a Sunshine Bulb 48" T12, 6500K, Lumen about 2750 with a CRI 95, available at Canadian Tire.

The Philiphs Daylight 6500K from HD were about 2850 lumen and CRI 84.
