A Workhorse 3 is less than $25.00 and the 32 watt PC
bulb is less than $20.00. You throw in some sockets and shipping and you are at about $75.00.
On the other hand, you can get the 10 watters for around $8.00 each. With sockets you are lucky to finish up under $50.00.
The light doesn't spread as well from the 10 watters. You will need to replace the bulbs with the built in ballasts every year. I think for the small price difference, you should go with the pair of 32w.
