not according to my nist light meter...lumen loss is the same...the spectrum is merely number spins...same salts in both arc tubes so how is the spectrum broader? also if you have a 400 watt magnetic coil ballast I would recommend a cmh bulbhortilux does have a broader spectrum and will probably hold it's intensity longer. you probably wouldn't be able to tell the difference on your plants though. just a matter of personal preference. you're not the first person to know about sylvannia bulbs though. some of us who have the cash and are looking for the optimal setup don't mind throwing down a little extra for a high quality bulb.

Here is a comparison grow for you to ponder.

These are the final products I plan to buy (I will only buy one bulb..I have to decide which I want to come with the ballast):

any thoughts?
if you would understand chemistry and how the lamps operate YOU would learn that it is impossible for the same salt/halide blend to create different colors...it is merely a graph...how do you know it is accurate? You do not...there is no law requiring the accuracy for spd therefore they can print whatever they wish...go to school some more before you declare who is wrong...jus sayingIf you take the time to look at the spectrum charts, maybe you'll understand how wrong you are.

digis dont last...mags last a lifetime...but have fun...keep 'em green
then how do you know so little about lamp operation and the physics involved?I don't need to go to school. I am a journey level lighting designer and technician.
that will take 30 years to make any noticeable difference...easy change the cap and ignitor about every 5 years INSTEAD of buying a new digi every 3-4Magnetic ballasts may last a lifetime, but their efficiency degrades over time. Fact.
