Not saying it pertains to these tubes, but years ago an engineer and gardner compared specialty agro-tubes vs. all-purpose tubes. The agro tubes had the better spectrum profile, but the all-purpose had superior over-all flux density (if that is the correct term) and out-performed in real-world tests as well.

I wonder the same about these bulbs.

It helps to read the entire page first. :) Cheapest I've found is 48 dollars per blue tube 4ft.
