Invented in 1964, HPS stands for High Pressure Sodium. It’s a light technology that has shaped how we cultivate indoor plants in a huge way. HPS bulbs consist of a narrow arc tube supported by a frame in a bulb. To improve efficiency, the arc tube is kept at an extremely high pressure. Sodium, mercury and xenon are usually used inside the arc tube in order to improve the light spectrum.
The most common way to start the bulbs is with a pulse start. This pulse starts an arc through the xenon gas and the lamp turns sky blue. The arc then heats the mercury which then lights up, giving the bulb a bluish color.
As the bulb heats and the sodium starts to vaporize it strikes an arc over 450° F (240° C). The sodium is then mixed with other impurities to create a more “white” light. Mercury helps add a blue spectrum light to the pure yellow of the sodium.
Here’s a list of the best 1000w HPS bulb for flowering plants:
Best 1000w HPS Grow Bulb For Flowering: Ushio Hi-LUX GRO Double-Ended HPS Bulb
This is the best flowering bulb out there, period. Nothing beats a 1000 watt double ended HPS for flowering, but unfortunately, there are very few good ones available. And the Ushio Hi-LUX GRO is easily the best among them.
At a time when most bulbs are manufactured in China, Ushio’s is engineered in Germany at an ISO9001 certified facility. The result is a very high quality bulb with a color temperature of 2100K and high red and blue spectral ratios for good photosynthesis efficiency. In short: it is perfect for flowering.
It has a lifespan of 10,000 hours, which is typical of good DE HPS bulbs. It provides a huge output of exactly the light your plants need, with a PAR of 2100 umol/s. The main drawback of this bulb is that it is only available in 1000 watts. And the high price, of course.
