Metal halides have the more balanced spectrum. The light they give out has a significant amount of light from the bluer end of the spectrum, which the plant uses to grow vegetatively. It produces plants with a small internodal length, with large leaves and thick stems. It produces the most natural looking plants. It simulates the light from the beginning of the year and is good for plants before they’re switched into flowering mode. They’re normally slightly more expensive than HPS. Recently, there have been ‘enhanced spectrum’ MH bulbs produced which also give off a significant amount of red light. Conversion bulbs are also available which plug into HPS ballasts which are actually MH bulbs. Useful for changing the light balance without changing the ballasts also.
Powerplant Metal Halide lamps are designed for your plants growth period as they deliver a blue spectrum of light at 4000 Kelvin.
Providing your plants with a pure blue spectrum of light will encourage them to become much bushier with thicker stems and lush green growth and this will help to maximise the potential of your plants when you enter your flowering period.
Simply remove the old lamp and replace with the new lamp.
Always make sure the old lamp has cooled down before replacing. Never touch the new lamp with your skin, make sure you use a small cloth or something similar.
We recommend that lamps are replaced every 12 to 14 months, after 14 months there is an appreciable drop in the lumen output leading to a reduction in crop yield.
In the event of a power failure, they need about 20 minutes before restating. They may restart earlier but it shortens the life of the bulb quite dramatically to try and start a hot bulb.

What is a Metal Halide Grow Light?
Metal halides are a type of HID lamp widely regarded as one of the best grow light alternatives for growing greens. They’ve been around since the early 60’s and have been further developed for several applications like car headlamps, street lighting and our favorite: Growing lush greens!
They are made very similarly to Mercury Vapor Lamps with the difference that they contain additional metal halide compounds in the quartz arc tube, in order to improve efficiency and color rendition (CRI).
Some manufacturers mix the metal-halide technology with others to improve light output and add a few variations into the color spectrum for a more complete solution.
Usually they’re rated with a high lumen output of around 100 lm per watt, a lamp life of up to 20,000 hours and pretty decent degradation rates. This makes them a valuable addition to our gardens.
Because of the nature of the processes that produce light within these lamps, they output significant heat into their immediate area. In fact, touching a bulb that has been running for a long time can result in serious burns.
Just like HPS and CMH bulbs, MH bulbs need a ballast to run. If the bulb is powered from a constant voltage source such as directly from the AC wiring, the current will increase until the bulb destroys itself.
When Should You Use a Metal Halide Grow Light?
Metal Halide grow lights are best used for vegetative growth. This means they’re great for making your plant produce dense and lush canopies with very little internodal spaces.
They’re perfect for growing all kinds of greens like lettuce, spinach, peppers, tomatoes, flowering crops in the vegetative stage and many others.
MH bulbs are also very good at stopping stretching. Stretching happens for many different reasons, mainly because the plants are not receiving enough light or because they’re not receiving enough blue light.
HPS growers usually add MH lights into their gardens to supplement light in the blue spectrum and keep their flowering crops from stretching in the different plant growth stages.
Choosing Your Bulbs
Like almost every HID bulb, Metal Halide bulbs come in many sizes. The most commonly used sizes for indoor and supplemental lighting are 400, 600, 1000 watts. With the 600 and 1000 watt bulb sizes being the most efficient ones.
For example, a 400w MH bulb may output around 85 lumen per watt consumed, while 600w bulbs output around 100 lumen per watt.
Hanging your Metal Halide Grow Light
Metal halides have come a long way, a few years ago they were not usually rated for universal positioning, you needed to carefully follow the manufacturer’s advice to decide how to hang your reflector and bulb. But not anymore. Nowadays most high quality metal-halide bulbs are rated for universal positioning.
“Excellent fast service, and the product is great. I am now running a halide light from my sodium ballast, and the vegetative growth on my tropical veg has went wild. My kaffir lime has put out 25 new shoots in one week alone!”
“My plants love this. Makes growing easier & quicker.”
“Quick delivery and very well packaged – as you would expect with this kind of item. Very impressed with the service from Gone To Pot Hydroponics.“
