Go with the 65 watt custom sealife brand 10000 k, your ballest will burn it and it is probly the most true brand of bulbs on the market. Let me post an email I got from one of their reps on actiic bulbs that I asked him. I wondered if the p.c. actinic was TRUE actinic 03 or not and this was his answer...........
Thanks for writing. There is a lot of confusion as to the term "actinic" and the differences between the spectral output between different types of bulbs. The term "actinic" refers to a spectrum that is maximized in the blue end of the spectrum. The term "true" was actually connected with the first high output bulbs that utilized special gases and phosphors to create a light that peaked at a very low wavelength, giving it a purple/blue appearance. This light was valuable due to its ability to penetrate deep into the aquarium as well as into the tissues of the organisms. The aesthetics of the aquarium were also improved over the harsher yellow lights that had previously been used. The term 03 is also synonymous with the word "true" and both generally refer to an actinic bulb that peaks in the 420-430 nanometer range. Our actinic peaks around 460 nanometers. This is also the range where photosynthesis is activated.
Our bulbs are not "painted" and utilize a special gas mixture combined with rare earth phosphors to create the actinic wavelength. Many years ago a competitor used this statement to scare people from purchasing our lights, but unfortunately rumors stick. Our bulbs, while different then the VHO actinics, will give a more natural look to the aquarium, as our bulbs simulate the natural environment.
If you have any more questions, please let me know.
