Per the manufacturer, the 48" high output T5 bulb produces 5000 lumens and consumes 54 watts giving it a 93 watt per lumen ratio. The 4 bulb fixture will produce about 20,000 lumens and consume about 208 watts depending on the ballast efficiency.

I can only offer an observation. The bulbs are 54 watts each making a total of over 208 watts in the fixture. Air circulation through the fixture provides cooling and surface mounting would limit the air movement thus over heating the bulbs and ballast causing premature failure of both.

Asked by
Grouse
Texas, USA

Most likely because of the heat generated by the balast. Depending on your particular situation, if you don't want to use chains, you can mount unistrut to the ceiling and then mount the light to the unistrut using spring nuts. This will put some distance between the fixture and the ceiling. I would check with a professional electrician or with the codes in your area before doing so. If you are in a shop or metal building, I would still put up the unistrut before mounting the fixture due to ease of installation. It allows tolerances you would not have if mounting directly to the beam.

This T5 4 bulb fixture is better suited for higher ceilings so I would look at 2 bulb fixtures. At 70 L per sq ft, you need about 36,000 L. The HO T5s (54 W) make about 3,500 L per bulb at half life vs 1,800 for the T8s (32 W). The T5s are very bright and with a 9 ft ceiling they may produce eye discomfort if the bulbs can be viewed directly. The math says you need 5 or 6 2 bulb T5 fixtures or 10 2 bulb T8 fixtures. Spacing should be on a rectangular grid with each light illuminating the same size area.

I helped my brother-in-law install 2 of these light fixtures a week ago. They came with a plastic quick connect plug for the solid copper run from the house. The wiring directions on the box still reflect the old wire cap method and nothing about these new plugs. A nice feature, but I needed to remove one of the wires after inserting into the plug and could not remove it. Any suggestions?

one leg of the 240V (which is actually 120) goes to the black wire, the other leg to the red wire. Each leg of 240 is only 120V when compared to ground, but 240V when compared to one another. Each leg is 180 degs apart (different phases).

240 volt has 2 hots incoming and no neutral. The fixture should have the red wire and black wire tied together with a black lead lose and this is to use for one hot. The white from the fixture should be used as the other hot for 240 volt. Also the fixture would need to be grounded as always. All lamps will fire when wired correctly.

For all four lamps to be on, the wiring diagram included in the box says to connect the Grey wire of the ballast to the AC Neutral (White) wire whereas the wiring diagram printed on the ballast (QHE4x54T5HO/UNV PSN-HT-SCL) in the product and from the ballast manufacturer’s (Sylvania) documentation available on their website, the Red/Black wire connects to AC Hot (Black). Which connection is proper? Also, am I correct in assuming that the Grey indicator in the product instructions actually refers to Red/Black as there are is Grey wire in the product?

The red/blk ballast wire changes to a gray wire at a wire nut. Actually either connection will work (red/blk or gray to neutral or red/blk or gray to AC Hot) This wire goes to a logic switch in the ballast so pulling it high or low triggers the 4 lamps. I prefer connecting it to neutral for safety reasons, but either way, there are only a few milliamps in the wire.

Janie, this would work for growing and starting plants as it is very bright. It is a High Output Light and I don't think there are Grow Lights that would match it so you will have to buy 4 HO Flourescent Light tubes for the fixture. I grow plants under older fluorescent fixtures (shop lights) in a stand with shelves and they work very well too as I have used Grow Lights AND regular cool white fluorescent tubes (even mixed them) and all my plants do well ... so the High Output Light will work well for plants too. Good Luck!

Most people will have this issue when they are wiring for 240 volts since there is no documentation. For 240 volts to work, wire your two hot leads to black and red and provide a jumper from white to red. without this jumper mine did not work. that was easy wasn't it joe.

Hi billyroper,

This fixture will go for a 240V application, but you'll need to find out what 2 hot wires that are coming from the ceiling (power source) and connect them to the 2 hot (line wires) coming from the ballast.

Without seeing what configuration you have on your circuits, I can't go further, but this is how they would be installed.

Depending on how much light you want or need but 60 x 100 I would recommend 35 lights. Space them 10 feet apart on 60 ft side so that would be 5 rows. Then the 100 ft span I would do 12.5 ft apart which is 7 rows and 7 x 5 is 35 lights. This will light the facility very good and I would suggest wiring each row on separate switch so you would have 5 switches for more control of the lighting.
