A HPS grow light can simulate sunlight very well. An HPS grow light uses sodium to produce light and it runs through a ballast. To have a more detailed comparison of an HPS grow light and some other grow lighting bulbs, look at the details below:
Grow Light Efficiency:
Let us compare a 400 watt HPS grow light with a 400 watt metal halide bulb and a 400 watt fluorescent bulb. The fluorescent bulb emits 3000 lumens at total efficiency. The metal halide bulb emits 36000 lumens at total efficiency. The HPS grow light emits an impressive 45000 lumens at total efficiency. An HPS grow light produces more light output per watt than most other grow lights.
Lifespan Of An HPS Grow Light:
An HPS grow light can last from a year to two years, approximately 18,000 hours. A metal halide bulb has a shorter lifespan of about 10,000 hours, while LED can last up to 50,000 hours. Of course with LED’s greater hours of service comes a very expensive price tag. An HPS grow light is recommended for those who have a medium budget for indoor plant lighting.
Color Spectrum Emitted:
An HPS grow light emits an orange to red glow, but is deficient in the blue spectrum. Even so, an HPS grow light is recommended for use especially during plant reproduction and flowering or root development. A fluorescent lamp emits light in the blue spectrum. It could be a good compliment for an HPS grow light to compensate for the HPS grow light’s deficiency.
Grow Light Kits Costs:
LED is so far the most expensive grow lighting system, but just because it is does not mean it is the best lighting kit available. The whole setup of your indoor growing plants is a great factor to any kind of light’s optimal performance. Cheap lighting can also produce good results as long as they are placed efficiently. A cheaper but still quality system, for example, is a 400 watt HPS grow light kit complete with a reflector, cables, screw fittings, the HPS grow light bulb and electronic ballast. This kind of kit could cost you only $150, more or less. Compare this with a 400 watt LED lighting kit that costs $400, now that is a huge difference. Warranty and free shipping might also be included when you order from some online stores and grow light brand retailers.
