Both bulb labels should indicate the wattage - 24W, 54W, or something else. That would help to know. The 4' Sunblaster 54W T5HO bulbs are rated for 4860 initial lumens.

Don't forget to consider the quality of fixture reflectors as well, they have a major impact on light distribution and the amount getting to your plants.

The newer Sunblaster reflections are quite good, highly reflective and well polished. They also wrap around the entire top of the bulbs. Most shop fixtures have plain white reflectors and ventilation slots on the top, which reduces the amount of reflected light.

Spectrum is difficult to check unless you have a spectrometer or PAR light meter, so I'm not even sure that's worth discussing.

Um. LED...

Which LEDs do you recommend for <$150?

Assumingly kit because most people don't have the skills or desire to assemble/solder up their own LED light setup.

I have about 14 Mars Hydro 300 W lights.

Yuan - What's wrong with the MarsII 700?

lumen/watt is much lower and it's also more expensive than the new smaller Mars 300W.
