    What is a double-ended grow light?

    Double-Ended (DE) Lights are high-intensity discharge (HID) lights that function at extremely high frequencies; hence, the operating current and temperature are adequately balanced and constant.

    Examples of HID lights include high-pressure sodium (HPS), metal halide (MH), and ceramic metal halide.

    Unlike single-ended lamps with a single connection, double-ended come with connections on both ends. Thus the filament inside becomes extremely hot, and as a result, a very bright light is produced than that of a single-ended bulb. Most people say that the light is 10% higher than single-ended bulb light.

    What’s the difference between double ended grow lights and single grow lights?

    • Single-ended bulbs have to be changed after every 6, 000 hours of use, while double-ended bulbs retain around 90% efficiency after 10, 000 hours of use.
    • Double-ended bulbs provide higher light output than single-ended bulbs as they are supported by both ends, while single bulbs have one connection. This also leads to more yields as more light and heat are produced.
    • Double-ended lamps are more efficient than single-ended lamps as the electrical current passes from one end of the bulb to the other.
    • Single-ended bulbs are less expensive than double-ended grow lights, but double-ended bulbs are easier to maintain in the long run.

    Things to consider when buying double-ended grow lights

    Light coverage

    Pick a DE grow light that covers the plants that you want. The area the light covers is usually determined by the size and design of your reflector. Some reflectors are like umbrellas and cover a wider area while others are limited to provide an intense and focused light down on to your grow plants.

    However, reflectors that focus on a single area are dangerous as they can have a hot spot that might destroy your plant(s).

    Type of bulb

    It is a good idea to select a double-ended grow light compatible with both HPS and MH lamps. But if you’ve to narrow down to one of the bulbs, then you’re better off picking a DE grow light that is compatible with HPS bulbs.

    Ballast

    There are usually two types of ballasts, and they are magnetic and electronic or digital ballasts. Pick high-frequency digital ballasts that are particularly designed for double-ended grow lights. They run cooler and are more efficient than magnetic ballasts.

    Digital ballasts not only run at the required frequency, but they as well as provide up to 6 different output wattage elections to get the most out of DE lights that operate between 600W and 1200W.

    Cooling

    Since the bulbs tend to generate a lot of heat, you need to choose a unit with goo cooling features. This will allow the DE grow light to work optimally during the entire operation.

    Price

    Buying a full double ended grow light kit is way cheaper than buying separate parts. If you’re a beginner and don’t know what features to buy, you’re better off buying a complete kit.

    Warranty

    This is a considerable investment, and you shouldn’t take unnecessary risks like buying without a warranty. Most of the top brands offer a warranty of at least 2-years or more. Also, consider buying your double-ended lamp from a re-known manufacturer with a track record.

    Our most frequently asked questions on double-ended grow lights

    What is the work of the ballast on my DE grow light?

    The ballast is vital as it controls the amount of power that goes into the HID bulb. The HID bulbs need a lot of power to start, and the power outlet cannot provide this. So, the ballast ramps up the power to deliver what the bulb needs to start.

    And when it starts to operate, the ballast again regulates power as the HID bulbs need less power to keep running. Power variations from the power outlet can damage the bulb, and the ballast does a great job of ensuring that the lamp gets a steady electricity supply throughout.

    What’s the difference between HPS and MH DE grow lights?

    High-pressure sodium bulbs provide a reddish or yellowish color needed by plants in their later growth stages. This color spectrum is essential during budding, flowering, and when plants start producing fruits.

    On the other hand, the Metal Halide bulbs provide a more natural whiter or bluer light required in plants’ initial growth cycle. This color is vital when the plants are seeding and vegging.

    Which bulb should I use in my indoor house?

    If possible, you should use both the MH and HPS lights in your grow room. However, this will turn out to be very expensive, and that’s why we recommend that you start by using the MH bulb in the early stages and HPS lights in the later stages.

    But if you can’t afford that as well, then you’re better off using HPS throughout the grow cycle. Although you will get long and lean plants, it is better than using MH light, which will give you a low yield as plants need red light to flower.

    Conclusion

    With so many double ended grow lights on the market, you need to select the right lamp for your greenhouse or grow room. Take your time and choose a unit that meets your needs and is within your budget.

    If you’re a small scale grower, choosing a complete kit over selected parts is the best option. But if you’re a large scale home grower, then you can go for the most advanced kits on the market or even hand pick parts as long as they are compatible.

    This is a huge investment, and that’s why you need to pick a quality double-ended grow light kit from a reliable brand with a good warranty. We hope our review has helped you in picking the best double ended lamp for your grow plants!
