I dont know anything about the omega. What i do know is that the phillips bulbs perform better overall than seemingly all of the other manufacturers on paper. Both in spectrum and output. I dont think the differences are enough to warrant replacing a good bulb. I just setup 2 sun spectra 315s with their brand of bulb. When time come to replace ill go with the phillips. There is a good 10 bulb comparison on youtube. Hope this helps?
