as most of you probably know i just purchase a parking lot metal halide fixture i am looking to get new bulbs so it will actually put out the right color spectrum i have a coralife pc light that is the 50/50 bulbs but wanted to get rid of those and only run the metal halides if possible. so what should i get? My LFS guy told me to get 20k and that is what they use but he also said to get the bluest i can get and i found a 22k that would fit. any suggestions? will i still need to run actinics?
