It depends on the light requirements of what you are trying to grow--but 1 or 2 should generally work.

It was for 3 bulbs. The fixture that I have uses two and they do last for a couple of years.

My plants were about 2 ft from the bulb and did well. So one bulb could cover your two trays side-by-side, maybe even end-to-end if you swap them around every few days.

Realistically, mine are mounted as overlapping 75X75 foot squares, so with two I am covering 75X150 feet well enough to see.

I have a three lamp fixture that looks like a 75-100 watt incandescent. So to be honest, your 60 watt example would need two of these bulbs. They are also candelabra based (minny) designed for a chandelier or a similar styled lamp.

No bulbs included. I took the opportunity to buy LEDs instead of halogens. Nice bright light and I often leave it on all night since they're so energy efficient. And yes, it truly fits in a 30 inch space. Actual width is 29 7/8".

same color as lamp -- don't have it handy but probably 4 1/2 to 5" to cover a 4" box. I didn't use it, custom made a galvanized pipe mount to give it an industrial look. nice fixtures.

I have 75 watt bulbs in them, but the dark brown shades mask a lot of light.

It's amazingly exact. it's 11X11. Just a suggestion, tho if ever you're gonna buy this fixture, I highly recommend if you'll use this bulb. For me, it's one of the best I've purchased because the light output, durability, and its efficiency are impeccable. Also, the color of the light and the shade blends well. Hope it helps (Pack of 4) G25 LED Bulb 6W, Warm white, 3000K, 40W Globe Bulb Incandescent Replacement, clear Cover, Dimmable, UL Listed, Energy star certified,

We have (3) 15 watt bulbs in one chandelier in one room and planning to put (5) 25 watt bulbs in another ceiling light and it seems to work fine. I don't think it can take much more though. Hope that helps.

We placed three lights along a 7'x3' counter. I am not sure two would be enough. The light is very focused, almost like a task light. The shade is on the small side so it also limits the spread of the light. That being said, I love our grouping of three!

75W is the maximum. I suggest you check this bulb that I use particularly for this fixture, it works really great: Triangle Bulbs (Pack Of 4) 8-Watt (65-Watt) BR30 LED Flood Light Bulb, Dimmable, UL Listed, Energy star certified,

The bulbs required are a little slim, so whatever you buy will need to be slim enough to fit. It takes two bulbs. This light is awesome though, I love not having to think about switching the light on in the hallway in our house.

I don't have access to the product right now and can double check a different time. I'm certain the bulb is not 6x4x2. I have it installed in a standard light fixture or our RV. It fits perfectly and works very well.

I have 2 of them in a 10 x10 inside patio and it lights it well..they take 60 watt bulb max and mine are on dimmer switch...so depending on size of your room. I would def say you would need 2.

Hard to answer but I suspect 4 would be adequate. Keeping in mind it sounds like you have fluorescent tube lights and these are not tubes nor fluorescent. Four of these lights will be more than enough to light a 20' x 20' room though.
