The wattage depends on the size of the growing area. It also depends on whether HID is the main source of light or if it supplements sunlight. And it also depends on the types of plants. 150/175 watts if HID lights 2'x2' growing area, and HID and sun light 3'x3' 250 watts if HID 3'x3', HID and sun 4'x4' 400/430 watts if HID 4'x4', HID and sun 6'x6' 600 watts if HID 6'x6', HID and sun 8'x8' 1000 watts if HID 8'x8', HID and sun 10'x10'

How do you calculate wattage capacity needed by a power supply?
To know what size power supply you need, add up the wattage requirements of all components and add 30 percent.
Silverado heater contol bulbs?
In a 97-03, the bulbs are soldered into the circuit board of the heater controls. Remove the heater control assembly and disassemble it to the board. Desolder the bulbs and replace with new ones from either radio shack or corvetteradios.com. The bulbs are 12v but I don't know the wattage. CorvetteRadios has bulbs for the CD player as well which are similarly soldered into the circuit board on the face plate.
What is the value of resistor do you use in 2.5volts bulb with use 4 batteries with 1.5volts?
If your batteries were in series the total voltage would be 6 volts, and it the bulbs were in series you would need a resistor to keep them from burning out. In order to know how many ohms the resistor would need to be you would have to know the wattage of the bulbs, or the resistance of the bulbs. If you don't know the best thing to do is use a variable resistor. Then you can adjust it or the brightness that you want.

What is wattage of an instrument if you only know it is 220V50Hz?
To determine the wattage of an instrument with a voltage of 220V and a frequency of 50Hz, you need to know the current it draws (in amperes). Wattage can be calculated using the formula: Wattage (W) = Voltage (V) × Current (A). Without the current value, the wattage cannot be determined.
Will a higher wattage hps bulb work in a ballast that came with a lower wattage bulb?
A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.
Where can you find Bradford novelty company Christmas tree replacement parts?
If you are looking for replacement bulbs then the best place to start is at Lowes, Home Depot or any place that sells halogen bulbs. With the original packaging you should have a re-order form which tells you the size of the bulb that you are looking for. If not then examine the bulb to see if it has any marks to tell you what it is or just take it to the store. Most of the halogen bulbs are MR11 with a G4 base and you just need to know what volt and watt bulb you need. If you are having trouble finding it locally then use google.com or ebay.com to find vendors. I had no problems finding replacement bulbs.
What are some tips for replacing Christmas light bulbs?
When replacing Christmas light bulbs, make sure to unplug the lights first to avoid electric shock. Use the correct replacement bulbs with the same wattage and voltage as the original ones. Handle the bulbs carefully to avoid breakage, and test the lights before hanging them up to ensure they work properly.
How many watts does it need to power a 12 volt air compressor?
To determine the wattage needed to power a 12 volt air compressor, you can use the formula: Watts = Volts x Amps. If you know the current draw (in amps) of the air compressor, you can calculate the wattage using this formula. Alternatively, you can check the specifications provided by the manufacturer for the exact wattage requirement.
Two light bulbs are in series how much power is dissipated by each bulb?
this is not an easy question. Assuming these are incandescent lamps with tungsten filaments, we need to know the type and rating of the lamps (bulbs) and the voltage. Incandescent lamps are highly non-linear and vary greatly in resistance depending on temperature--at lower voltage, the temperature is lower and the resistance is less. The problem is finding the stable operating point at the lower voltage. Probably the easiest way to answer this is build the circuit and measure. As a general rule, if the two in series bulbs are equal wattage, each one will dissipate 1/3 of its rated wattage (at half voltage). So two 25W bulbs in series will each dissipate about 8W, or 16W total.
How do you change bulbs in a 1997 Blazer?
