Wait so if I understand you. If my ballast is say 5 years old and I buy a new bulb.in plain english that means that instead of your hps lamp lasting 8-12 months before you begin to lose the k rating, it will now last up to 3 years before the spectrum begins to change. ( at least thats what the manufacturers say) go with digital,
As a result of the ballast being older the new bulb will be week right out of the box? If so how often would I want to replace the mechanical ballast? Im also not sure its mechanical. Are digital and mechanical the only types? Thanks again for your time answering all our questions.
