The dimmable digital ballast may have several settings. For example, three separate settings, such as 50, 75, or 100 percent for maximum lighting control.
Things We Don’t Like:
The blue protective plastic needs to be taken off for the reflective material to reflect properly. The German aluminum inside the reflector is over 90 percent reflective.
The bulb is rated at 400W with a color temperature of 2100K. The generated light spectrum is not only optimized but also delivers high photosynthetic active radiation for healthy plant growth.
Installing either of the single ended bulbs inside the air-cooled reflector is remarkably easy. Just make sure you wear your cotton gloves because hand oil can damage the glass.
If you are looking for a consistently high performing HPS MH grow light kit, look no further than the Vivosun Hydroponic 600W HPS MH Grow Light System.
The next important consideration you have to make is choosing between single and double ended high pressure sodium grow lights.
The Ultra Sun System 150W HPS Grow Light is a self-contained, high-intensity lighting system that is a suitable grow light for small spaces, such as closets and grow tents.

Are you planning to grow plants indoors with no help from the sun? It's doable with the help of high-performance high-pressure sodium (HPS) grow lights.
Use a staple gun to reinforce anywhere you use duct tape, including where the ducting goes through the hole you made in the foam.
Conclusion: MH/HPS Ended Up Being Right For Me…
There are many different kinds of hoods for HID lights, from wings to cooltubes to air-cooled hoods. The hood will reflect the light from the bulbs down at your plants, and may come with special cooling features, too.
A 150W ballast is not as efficient on electricity as the bigger models, and will only be able to cover a 2′ x 2′ (0.6m x 0.6m) area, which is sufficient for 1-2 plants. Many models of 150W HPS lights come with a built-in ballast & hood, which can make setup easier and usually comes with a way to air-cool the light (and hook up to an exhaust) if needed. If you’re growing in a very short space with less than 4′ (1.2m) height, or an oddly shaped space, you may want to consider going with several smaller CFLs instead, as you may be able to get better light distribution in a small or awkward space for about the same amount of electricity.
Things to look for in a good hood/reflector:
About Sirius Fourside
I like using foam + corrugated plastic because it’s inexpensive and easy to cut the hole for the exhaust. Having the foam/plastic combo in the window increases the suction in the room so more hot air is vented out and blocks light (no light gets in or out). As an added bonus, the foam dramatically reduces the noise of the fan (so you can just barely hear it even when you’re standing right outside the window).
600W – covers 3.5′ x 3.5′ (1m x 1m) area up to 4′ x 4′ (1.2m x 1.2m)
