Yes, in terms of PAR, too, Gro-Lux and other plant-specific fluoro tubes dominate the market in PAR per watt.
Around or less than half the amount of lumens are required for roughly the same PPFD as other bulbs.
The closest challenger is this test is the Mitsubishi MH lamp. But the fluoro tubes are also more efficient than MH in lumens per watt. Win-win.
Then there's the sun, more efficient than everything except plant-specific fluoros.
