LIGHT OUTPUT could also refer to the amount of light emitted from a certain source. For example, a brand new HID light bulb will put out a certain number of "lumens" or "Lux", which are two standard measures of light. As the bulb ages, it will slowly start to put out less and less lumens, thus making the light slightly dimmer
. Apps can be downloaded to any android cell phone that use the phones photo-sensor to measure light output so you can test the output of your bulbs and compare them to specs or other light sources. Some professional growers will change out their bulbs after every crop.

MH lamps are available in 175,200, 400 and 1000 watt sizes. HPS lamps come in 50, 75, 150, 400 and 1000 watt sizes. San Agro comes in 430w only, but it works with a 400w HPS ballast. Each lamp requires its own ballast, which comes with the fixtures that are designed to use these lamps, and are also available separately.

What is the best grow lights to grow *********


That depends on what you're trying to grow and what phase the plant is in. Certain plants are adapted to grow in the shade or in warm, sunny environments. Depending on the plant, one type of light may work better than another. For example, if your plant needs a shadier environment, then a regular incandescent bulb may work best.

The other factor that goes into choosing the right grow light is what phase your plant is at. For example, a high-pressure sodium bulb may be best when your plant is in the flowering or fruiting stage.

Personally, I love using LED grow lights. Modern LED bulbs are more energy-efficient (they produce more light with less power), so they cost less in the long run. They also produce less heat, which means you don't have to worry about a ventilation system. Plus, they emit light wavelengths that correspond to the peak absorption peaks for most plants.

When choosing your bulb, you should look at the requirements of the plant and how those requirements change as the plant continues to grow. Keep in mind that the larger your plant gets, the more light it will need, so plan ahead.

Just bought 4 new 1000W Super high output HPS bulbs. Only one of them is really bright. The others are about 80% by eye. The brightest one is nearest to the transformer stack but the others don't...


A ballast for a 1000 240 volt fixture will lose a small amount of output over time , but should nt be too noticeable . I suggest you take one of the dimmer bulbs and install it into the fixture that has the brightest bulb in it now . If the new bulb is now the brightest of all , then you know your other ballasts have lost some intensity . I have also seen on some bulbs depending on the gas inside the glass( ex. HPS or Metal Halide) which gives off the different color , will take a while on initial start up , to burn at full intensity . It is also possible that you were given used bulbs which would explain the 20 percent loss in intensity . Good luck

I have fragment shards inside my grow light can i still use it or is it unsafe which im guessing it is ?


Yes it is most likely unsafe. It depends on which glass is broken, HID lamps often continue to operate when cracked or broken, resulting in emissions of harmful levels of ultraviolet (UV) radiation

My low voltage landscape lights are constantly going on and off once the timer activates them initially. I suspect there is a short somewhere, but is there a good way to locate the short besides pulling up...


Your transformer must have output greater of the total wattage required of the entire system. Example: Putting lights that draw a total of 250 watts with only a 180 watt transformer will result some lights not working, or dimming and flickering, or intermittent power outtages. I learned this from experience. Always go with a transformer that has more wattage available than what is needed. Also, using the incorrect gauge of wire can cause the same issue. Wire creates resistance. Distance the power must travel through the wire creates more resistance at the end of your run than the beginning.

NEW 600W L.V.TRANSFORMER DOES NOT PRODUCE ENOUGH POWER


This is more than likely what has happened . I am going to guess that your original low voltage trasformer was a 120 volt .6KW. Or 600watt transformer that has one lead from it to the lights . The newer less expensive transformer is also 600 watts , but the new one may have 2 sets of wire terminals on the back( 4 screws ). If this is the case , you have a transformer that is 600 watts output but it has 2 seperate 300 watt outputs that won't run 600 watts from 1 set of output screws . You will have to seperate the lighting load and may have to run an additional low voltage wire to half of your lights . In other words . Put 300 watts of light on 1 set of 12volt output screws and 300 watts on the other se of output screws .that will solve your issue . Good luck and enjoy your lights again . John

Growing lights Types


There are three major types of lighting systems available right now: incandescent, fluorescent, and high intensity discharge. Incandescent lights are horribly inefficient (especially the screw-in "grow bulb" type) and really not an acceptable option for plant growth. Although they are inexpensive to purchase, their cost of operation makes them the costliest source of light.

Fluorescent or hid Comaparison


Until the early 1980's most indoor growers used fluorescent lights to illuminate their garden. These tubes have tremendous advantages over incandescents. They emit about 3 times as much light as an incandescent (given the same wattage), and the light spectrum is one that plants con use more effectively. However, they do certainly have their limitations. Light is emitted over a large area, so it is not concentrated. Because of this, the lights have to be hung very close to the plants (usually within 2" or so from the grow tips), and constantly moved to accommodate plant growth. This makes garden maintenance rather difficult, even when the lamps are hung on chains. Florescents are, however, very useful in cloning, and starting seedlings. Because in these stages, a plant is not growing vertically very quickly, the disadvantages of moving the lights are reduced. They also put out a more gentle light than the HID lamps, and release less heat. The fact that they produce less heat is very important to those growing in enclosed and not-especially-well ventilated spaces. If you choose to use fluorescents, it is best to purchase the 'cool white' variety. The ones that are sold as grow lamps (including grow-lux, vitalite, etc.) are much less efficient than a standard fluorescent, and just do not put out enough light to be useful. The slightly different spectrum produced by these lamps does nothing for most plants. Some growers have reported excellent results by using a mixture of cool-white and warm-white lamps in a florescent fixture.
