Though incandescent bulbs are the cheapest to purchase, over time they are more expensive to operate due to their inefficiency and short life. They are also much less bright than newer bulb types, providing about 10 to 17 lumens per watt. The average lifespan for incandescent bulbs is 750 to 2,500 hours. Incandescent lighting will most likely be obsolete within the next few years as newer and more efficient technologies continue to develop.
- Compact Fluorescent Lighting (CFL): More energy-efficient but contains toxic mercury. Compact fluorescent lighting is becoming increasingly popular in a variety of places including residences, businesses, greenhouses, and livestock and poultry houses. This form of lighting comes in a variety of lamp types, making it extremely versatile. Compact fluorescents are available in magnetic and electronic ballasts. While magnetic ballasts need a short amount of time to reach full brightness, electronic ballasts light to full brightness immediately. With an efficacy of 30 to 100 lumens per watt, compact fluorescent bulbs normally last 7,000 to 24,000 hours depending on bulb type. When purchasing compact fluorescents, it is important to check the temperature range on the packaging or through the seller because some bulbs are only appropriate within specific ranges. If you are looking for a type of lighting that can be used in hard-to-reach places and be on for a long period of time, compact fluorescents are the most cost-effective and efficient option.
- Metal Halide Lighting: Produces a crisp, white light ideal for large spaces. Metal halide bulbs produce a crisp, white light that makes them ideal for commercial and residential applications including grow lights and athletic fields. Metal halides are recommended as grow lights in areas where no natural lighting is present and also work well when starting seeds. They are ideal for lighting large indoor or outdoor areas. With a lifespan of 5,000 to 20,000 hours, metal halides generally produce 70 to 115 lumens per watt.
- High-Pressure Sodium (HPS) Lighting: Common for outdoor use but less energy-efficient than LEDs. High-pressure sodium lighting is ideal for parking lots, security lighting, illuminating roads, and highway lighting. If you want to use HPS lights for growing, it is recommended that they are used as supplemental lighting where some natural light is already present. High-pressure sodium lamps should be used when seeds have already been planted to promote budding and flowering. Producing a warm white light, HPS lights have a lifespan of 16,000 to 24,000 hours and produce about 50 to 140 lumens per watt.
- LED Lighting: Highly energy-efficient and long-lasting. Compared to fluorescent lighting, LED lights are far more energy-efficient and long-lasting. They are a modern alternative to fluorescent and have more features like color-changing, dimmable, programmable, and more. LED lights are made up of light-emitting diodes (LEDs) that produce light when electricity is passed through. This means that they light up instantly on the flick of a switch while other lighting types, like fluorescent, take time to warm up. Due to the advancements in technology, LED bulbs can be up to 80% more efficient than fluorescent and last for an extra 10,000 hours, which means they cost far less to run and have less of an impact on the environment. They are also safer to dispose of as they don’t contain harmful substances.
