I've got a Hamilton 14k 250 watt mogul on order and according to hamilton they say that the 14k is better run on it's own without actinics. I still plan to run my 55w pc actinic anyway and will just have it come on before the 14k does and after it goes off so it'll be off when the 14k is on. That way I'll still get a dusk to dawn effect. I think I agree with invigor that you will go from blue to white if you use the 10k t5. Just a thought but you might want to try an actinic only t5 with it.
