What is the perfect light spectrum from two hps lamps?
Red spectrum
Will a mh luminaire run a hps lamp?
It will not. A HPS lamp has a much lower ignition current than a MH lamp. There are lamps called "multi-vapor' "MVH" that will work in a MH luminaire. you can run metal halide in hps but not hps in halides.
Does led lights contain MH in it?
LEDs do not contain the toxic metals found in HPS (High Pressure Sodium) and MH (Metal Halide) lamps! That's less hazardous waste to deal with, allowing for easier recycling and safer disposal. for more info and lights come to tacticallight.com
How much power does a 250 watt hps light use an hour?
A 250 watt HPS light will use 250 watts of power per hour. This means it will consume 0.25 kilowatt-hours (kWh) of electricity in one hour of operation.
Can you run a 250w hps through a 400w hps ballast?
No!
Will a hps luminaire run a metal halide lamp?
Yes the ballast and starter are the same you can run halide in hps, but not hps in halide.
What is full name of HPS Ahluwalia?
The full name of HPS Ahluwalia is Harpal Singh Ahluwalia.
How does high-pressure sodium work?
HPS lamps work by subjecting sodium to high pressure. The result is warm golden white lighting that has indoorand outdoor uses. Indoors, HPS lamps serve as grow lights and in greenhouses. Outdoors, they meet agricultural and horticultural needs for lighting, and security.Sunlight can be visible, or invisible. Invisible sunlight is infrared or ultraviolet, depending on whether it's drawing on red or blue color extremes. Most plants need orange-red lighting.Additionally, infrared lighting encourages quality flowering, ultraviolet quality shapes and stems. HPS bulbs meet visible, and invisible, lighting needs.
What is CFL mhl and hpmv lamps?
The abbreviations are CFL - Compact Fluorescent Lamp, MHL - Metal Halide Lamp, HPMV - High Pressure Mercury Vapor, and one more is HPS - High Pressure Sodium lamp
Can you split 2 light using 1000w hps ballast?
No, a 1000w HPS ballast is designed to power one 1000w HPS light bulb. If you want to power two lights, you would need to use a ballast with enough power output for two lights, like a 2000w HPS ballast.
Can a 400 watt high pressure sodium bulb be used in a 400 watt metal halide ballast?
I actually have a 400w hps ballast and I can also use my 400w metal halide bulb in it with no problem. So what your saying is they do, but they dont? the answer is, they dont. You can get universal bulbs hps to plug into a mh ballast they have a miniturized igniter inside the bulb. As I understand it, a 400W metal halide bulb can be used with a 400W hps ballast, but not the converse. A MH bulb has the igniter in the bulb, and the HPS has it in the ballast--which pretty much goes along with your comment above. Apparently the double presence of the igniter in the HPS setup is OK.you can run metal halide in same wattage's but not hps in metal halide systems.you can run such as (same wattage's)250 watt metal halide-400 watt halide ect in hps systems but not hps bulbs in halide systems. they make conversion bulbs to run halide in hps as well and vice versa.
Best lights for growing marijuana indoors?
Since there is no sun in your closet you will have to provide a sun loving plant like marijuana with a lot of artificial light. There are three options available to the grower: fluorescent lights are cheap, efficient, and don't put out much heat. Metal halide, or MH bulbs, are more expensive but put out much more light than fluorescents. They also put out more heat so ventilation is needed. MH bulbs also require a separate ballast in order to work. High Pressure Sodium lamps, or HPS, put out as much light as MH lamps but with a little less heat. Ventilation and a separate ballast are also required. Fluorescent lights Fluorescent lights are the cheapest light to use. They run at about $2 a tube. They produce little heat so ventilation may not be needed unless the space is very small. The light spectrum put out by these lights is suitable for all stages of growing. Because fluorescents disperse light over a large area, they need to be kept within three inches of the tops for the plants to receive enough light. This means you will have to mount the lights in a way that the can be raised everyday. Metal Halide Lights Metal halide lamps put out the most light. They also produce alot of heat. A strong fan is needed to keep room temperatures down. MH lamps put out light mostly in the blue spectrum. Blue light is used best by the plant during vegetative growth. MH lights can also be used for flowering with no adverse effects. A separate ballast is required for these lights to work. They come in sizes from 40 to 1000W. One 1000W lamp will provide enough light in a closet to grow four plants. High Pressure Sodium Lights High pressure sodium lamps put out almost as much light as MH and with less heat. Good ventilation is still required though. HPS lamps produce light in mostly the red and orange end of the spectrum. The plants uses this light best when flowering. HPS lamps can also be used for vegetative growth with little slow down in foliage production. HPS lamps require a separate ballast for operation. Some growers switch between MH and HPS depending on what stage the plants are in. MH is used in vegetative growth and then the light is switched over to HPS once flowering begins. Most growers use fluorescents to start seedlings and root clones. The fluorescents are weaker than the MH and HPS lamps and therefore do not stress them too much. Choose whatever light is best suited for your situation. If your are growing in your attic go with MH or HPS. If your growing in the closet like us, then use fluorescents. (For the rest of ths document I will assume the reader is using fluorescent lighting)
