PPFD light question..

[frank88]

I made a table with the values given on some of the most popular bulbs on the market .. of course data taken from this site:
http://www.manhattanreefs.com/lighting

Here's the table of the BULBS + PPDF on the side...


there is much difference in PPFD between the bulb and bulb ...

I wanted to know ... the higher the PPFD is the best bulb?

or a bulb with a lower PPFD might also be better for health (growth and color) of corals?

I have considered all the most famous lighted lamp with electronic ballast icecap
