I haven't seen many people do so, you can't wait till you find some 6500k? I got my 26w (2700k) and 23w (6500k) both from Lowes. Lol I feel like you are doing what I did. Ya know I looked at those same bulbs but never bought them when I was looking for mine. Honestly man you'll eventually find what you need. Don't substitute shit. 6500k (blue) is for veg and 2700k (red) is for flowering. You can mix the 2 colors on both light schedules but its recommended you have those colors for those periods.

Veg you will want 6500K or close to it, 6400k sometimes
Flowering you want 2100K to 2700k. 2700K are CFLS, 2100k are from the HPS.

my friend you do not want to use the lizard light as you call it. take for instance what the uvb light spectrum is. you get the highest uvb outdoors during, in my area, end of june, july. it is a finishing bulb actually, if you use it for veg i'm afraid you won't get very far. the 6500 k cfl bulbs that you find at any major dept. or utility (lowes or wallyworld) are the best bulbs IMO to start any seedling with. i use as low as a single bulb, 1 23w to start seedlings with and have great results. if you do decide to use the lizard lights let me know how it turns out. uvb or tanning bulbs tend to burn the crap out of anything you put them on(live vegetation) there are warnings on the label about exposing yourself to those bulbs, think what they might do to your plants. ed rosenthal has a fairly indepth article in his newest book, the growers handbook, about uvb bulbs, there is just too much information out there readily available to make mistakes on expensive seeds.
I'm sorry but IMHO them lights are fine. Plants use light from a range of 450nm - 700nm. As the K (Kelvin) is concerned, that light is within these wavelengths. There's the Physical details to make this easier to understand. People tend to say 'use 6400K' because generally they are the most commonly available Colour spectrum. Use them, aswell as the 2700K bulbs because both spectrum effect the plant differently. I Hope I explained that well enough for you to understand 
In regards to the UVB being dangerous.. The sun gives out UV rays. The plant will not get a sun tan or cancer, it's a plant, if it will burn the plant or thing under it, think about all the animals and people in this world who are under the sun.
The chance if two UVB lights giving someone cancer are tiny, but if this is your concern you might aswell not go out in the sun.
