Does anyone know what is the angle at which the light is dispersed onto the tank to focus the light rays onto the plant and avoid light scatter?

According to the Finnex website the light spreads at 120 degrees. "The durable high output LED bulbs are built to last 40,000+ hours. With a LED spread of 120 degrees, this slim LED bar lights up the largest of aquariums."

Not sure if the exact angle is that important. In nature, sun light is emitted onto plants at all angles at different times. I have used this brand of LED lights for fresh water plants for years. The plants grow and multiply, and that was what i wanted. During water changes, I now need to heavily trim the plants, or the aquarium is over whelmed by the plants. I never had this type of growth with the old bulbs. Hope I have answered your question. I have also found these lights to be much better than other LED's I have tried out. The oldest light I have, has been used daily for over 5 years without any of the LEDs going dark. Not sure if the exact angle is that important.

No, unfortunately it does not. If you put small plant containers on either side of it, they can catch some of its light from the sides. I've done that and it still helps those plants.

I agree. The light doesn't generate any heat so it can be placed close to your plants. A few inches away will allow your plants to receive the full spectrum of light generated by the different colored LEDs .

I measure 1 3/8 inches from the top of my tank edge to the top of the fixture. Be aware that the wire feet of the fixture hang outside the top edge of the tank, so there may be interference with your canopy at those points.

The angle is not very wide, if wide at all. I am using 4 of these light one side of my house. They act more like floodlights, From a distance of about 20 ft. the lighted area is about 5 to 7 ft. wide (that is the area where most of the light is concentrated). The angle of illumination is about 15-25 degrees

I used this item all sorts of way's with out any issure's ! This does not produce a diffuse light up close and in my opinon it shows a sharp beam.You can connect several led infr. lites! As far as angles are concerned you can position it at any angle.If this does not suit you there is other products to adjust your needs.I hope this was some what helpful. DAVE S

The unit is a plant grow light--it mimics the spectrum of light needed by plants--more of a daylight bulb--specific to plants and aquariums. Hope this helps

Because its wide angle, it does pretty good in normal inside room lighting. It is about 160º wide angle I think. About equal to a 22mm. Hope this helps.

I placed the reflective target inside an open storage container in bright mid-day TX sun and sighted in at 25, 50 and 100 yards with no problem. The key is to place the target in the shade for more contrast.

I would not recommend this light if you are looking for bright lighting. The light only focuses on the middle of the tank, leaving darker spots on the edge. My 10 gallon tank has this problem, where it is insufficient light.

Depends on the type of plant. It's not super bright so while it'd probably be sufficient for low to medium light plants, the light is definitely not strong enough for high light plants unless you have a shallow tank, and position the plants right below the light.

It's angled just right so that if you have anything with screens the stage lights don't reflect into your eyes. I thinks it's only a couple of inches. The angle is probably only like 8 degrees or so. In very happy with it.

Although the beam of light is not adjustable it is very concentrated to the direction it is aimed. The neck of the light is very adjustable and can be Aimed many directions.

Do not know how to answer that. It is MAYBE about a 33 degree angle? Pretty much of a spot light. Not a flood light.

Generally speaking if you place the illuminator approximately 35' (approximately 11 meters) from your target you will get a 25'x25' (approximately 8m x 8m) spread. The closer you place it to your target the smaller the spread will get but the denser the light spots will be, accordingly, the further from your target results in a larger spread with sparser light spots. On really large trees I like to place one on each side for full effect. The light spots will penetrate throughout the tree giving it sort of a 3-D result.

depends on light and ventilation system - light should reach all the vegetative canopy

I seriously doubt it, if that's the only light the plants receive. One of these things gives enough light to make a betta tank (about 1.5 gal, and broader than it is deep) fairly bright to show off colors, but I can't see one being enough light for 15 gal of planted tank. However, I have no idea what wattage of light it's equivalent to (in order to estimate 1-2 watts per gallon); this is only my personal impression from looking at my own small setup.
