Does this light give off sufficient light for 2 trays of starters (about 1ft x 2 ft each one), or would I need two lights-one for each tray? Thanks!

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.

I would get two lights, one for each tray if that is your only choice and within budget. Definitely grab a reflector hood too. Although 1 bulb could work, I feel that 1 bulb would be bare minimum and you would want to move the trays around to help distribute the light evenly in a 1 light set up. I personally use 3 of these lights for 1 tray, for max/best results. But then I tend to over do things. =) Good luck!

I would work along with a reflective holder. Placement should be pretty close. I used it in a dark basement and started seedlings. I had trouble, but found out that the topsoil I used was extremely inferior. The light was fine. I, also, lined the box that the seedlings were in with aluminum boil. The foil was a brilliant idea that I had ran across.

assuming this is a freshwater planted tank, the good thing about hanging fixtures is you can adjust the height of the fixtures. I would saying having two would be ideal, and give an even amount of light over the entire length and depth of your tank. having only one would give you enough light in the tank under which the light is positioned. but having two would give you more even light over the entire tank. Unless you want to create different sectors of your tank for low light and high light I would use two. With two you can still create those different sections, by adjusting the height of each fixture, and also give you the ability to change different areas of the tank any time you want. assuming this is a freshwater planted tank, the good thing about hanging fixtures is you can adjust the height of the fixtures.

Yes that is what it was designed for. If you use in an outside light it does best with an outside light cover that is not opaque or reflects the light back unto itself. This tends to shut them off periodically and it may take a while for them to come back on. Also if you are using more than one, say for example a set of garage lights. They should ideally be 10 feet or more apart so they don't cause each other to shut down. They are very cool though and I love mine since I have no switch inside my house to turn my garage lights on, this solves the problem when it gets dark.

This light is very nice for starting and vegetative growth, you will want to have many "plants" under this light. You will, however, run out of room as your plants near the "fruiting" stage. If your plants are healthy you will end up with only 2 to 4 plants worth of space in the area of productive light provided. I wouldn't trade this fixture for any other comparable fixture.

No, not as much as two florescent tubes. But two will give you more light the the florescent. The wiring harness to install actually is good for two led tubes, so you could easily start with one and see how you like. No extra work involved in adding a second tube later.

Roger on the light that I got in the directions it says one light is good for 60 gallons and on the tank size that they give for each light is 36inches , so I would guess that one light is good if you are doing soft corals . I know for me this light is fantastic all of my corals are doing fine under this light they open fully and seem to like it. I'm doing 50% blue and about 30% white on a 30 gallon tank.

I use this light to illuminate a 4'x4' tray. The plants on the very edges all lean inwards towards the center. I went to a different reflector, 24"x24" and this eliminated the plant lean. I think the reflector would be good for a 3'x3' grow at max. The ballast and bulbs are good though.

I used a standard motion/light detector with two of these and it works fine. Not sure that only 1 10W light will work as there is a minimum turn on requirements. You need to look at the minimum load turn on specification. The alternative is to buy this light, but already has the light/motion sensor built in. They are just a few dollars more. These do not create bright white light, like for reading. Also make sure the wire length is long enough for your application. I got fooled and some wires were only 6" long on some lights I bought.

These are great grow lights but they are small. I have two lights and that about does two big plants. If you want to start seedlings it will do a lot more but mature plants, especially if they are big, will need more of these lights. The plants love them though.

It all depends on how many your looking to grow and from what stage of growth. This light is perfect for seedlings, clones and small plants. It covers a 2*3 area, just remember that cfls need to be close to the plants to produce vigorous growth. I found that 6-10inches above the plants is the sweet spot for this light.. You can fit 6 decent size plants under it but its better for a tray of clones or seedlings....

Get two. I love mine. No problems with the lights or the company. My corals and fish are doing amazing. Was definately worth the money.

I would say you will need 2 at minimum. You will have to hang fixtures at height that will give you the spread you are looking for to cover your tank.This light has been very good to me with LPS and a few SPS corals because it is adjustable for intensity. I have 2 over a 55 gal. (48" Long) tank. In 2 months I have seen a lot of new growth in my corals.

This light should do the job. For the price, two would be better. I really like the results I'm getting.

are you getting just one or more than one? Either way, since there are 4 light burbs on each, it's definitely going to create circular flashlight effect. If you put it on high like on ceiling, it may light evenly, but it's going to be pretty dim. (almost similar as nonexistent)

I'm not sure? To insure you have a spare light or two simply buy a kit with more lights that you think you will need. These lights are very bright so I would suggest you temporarily attach until you get the lighting effect you want; then clean the attachment area with rubbing alcohol for the permanent attachment. Good luck... j.d.

I'm having trouble remembering now--between 1-2 hours I believe. Regarding the amount of lights, I would feel better having two--but it depends on what type of setup you have going. I can imagine a decently lit interview with this light and two smaller LEDs for a 3 light set up, as this light is reallly bright. My intention is to have two though for shoots.

I would think you would need 2, depending on the length of your tank. The light covers about 24". I'm using 3 on a 6' long tank and it lights it nicely.
