How much room is there between the bulb socket and the end of the inside of the canopy? I'd like to use 13W LED downlights for a planted vivarium.

I have a medium sized one. It has three bulb sockets total. The left two are faced towards each other and are approx. 11" apart. The third socket is faced towards the end of the canopy, and is approx. 5.5" away from the end.

The bulb itself is about 1" above the top of screen portion of the aquarium lid it sits on. I hope this helps.

About five inches from side to side. The skimpy sides don't do a good job of reflecting. If you can find a hardware store or lumber yard that will cut flashing to length, buy five feet of a narrow width (3", or 4" cut in half lengthwise), and duct tape it on so that 1 1/2" extends below the sides. Or buy a better fixture. I've found two tube lights to be inadequate for seedlings, but if you can find a cheap, narrow fixture, you can buy two and join them together with a couple lengths of 1/8"x1/2" aluminum bar (across the top, pop riveted, careful when drilling into fixture). You'll still need additional reflectors on the sides of the joined fixtures. I made a four tube, four foot light for less than $30 this way. About five inches from side to side.

just measured the one inside ours. it's 3in from the bottom of the bulb glass to the tip. there may be about 1/4 or so extra space you can use, but stick to 3in and you should be good.

T5 - 4 ft lamp should be compatible across the board. Mine are used as grow light for my wife's African Violets and other plants - they sure like it and more blooms than ever before. She put a couple of Pontsettas on the shelf last week and they are no just blooming more, but growing too.

Obviously the illuminated area would depend upon the distance from the bulb itself. As you may know, the beam is adjustable so I took some measurements of the smallest and largest widths of the beam. The smallest area of illumination is 1/8" width per inch away from the bulb and the largest area of illumination is 1.1" width per inch away from the bulb. So you'll have to take that info and apply it to where you intend to place the lamp. The bulb sits about 4' above ground level, FYI.

Nate Berkus said on one of his design shows that 36 inches between fixture and table is a good standard. That gives enough room for a centerpiece and still leaves it easy to change the bulbs. I bought this fixture and put a swag chain on it and hung it in my living room in the corner with a low wattage bulb to just have a little light in there. It's pretty heavy.

Jane, I'm looking at the lamp now. . . 71 mm end to end. That 2 and 13/16 inches. The exposed part after the socket screws is 53 mm. I hope that helps. John Doe

Hi, Thank you for contacting us. The dimensions of the space within the illuminated area is 13¼W x 21H. Have a great day. Regards, Howard - Lighted Image.

the LED light is 1 3/4" from end to end.The bulb, excluding the metal part is 1".

Don't have time to measure but nothing that large. You can use socket dimensions to see scale in photo. They are fatter than glass bulb s

I do not recommend this light. It only lasted for a week before it quit working. The LED light is only effective for the area right under the light. So a 12" x 12" square is all of the effective coverage you should expect.

About 4(3/4)" x 6(3/4)"Once you get everything in it will look great. Mine did however condensate enough to ruin my LEDs. I would recommend sealing the plastic around the light with a little caulk before using.

No glass lens, bulb socket points to the side, and nothing 3" long will fit in here. I used LEDs that are less than 1" long, I believe they are described in my review of the light fixtures.

somewhere around the perimeter on the top. put as close as you can to the edge ,otherwise there will not be enough clearance for the light to fit properly

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.

24-36" because you want the LEDs to span the length of the tank. You'll have darker spots on the end with the 18-24" light.
