It probably has the power to handle it, but I haven't tried running multiple lights off of a single programmed socket. It also has a downside of only reacting to a single temp probe. If you want the temps to possibly vary, but the lights dim/brighten together, then it may be a good route. There are options like the Herpstat2 which has two outputs and two probes so you can control the two fixtures independently if that's more along the lines of what you're looking for.
