Can I use a 600w HPS bulb in a 1000w ballast?
Using it to dim down a bulb, for example to run a 1000w watt bulb at 600w, is not ideal. The better use is to dim the ballast down to 600w and then use it to run an actual 600w bulb. That is the big advantage of a dimmable ballast: it allows you to power bulbs of multiple wattages.
Can you use a 400w HPS bulb in a 600w ballast?
Yes, you can run a 400 watt lamp in the 600 watt ballast dimmed to the 400 watt setting. Since the voltage output for the 600w ballast is the same as the 400 watt lamp this combination has no issues.
Can I use a HPS bulb in a MH ballast?
Yes, you’re allowed to change your mind—at least when it comes to MH and HPS lighting. Although the two fixtures use what are normally incompatible ballasts, conversion bulbs will let you switch lighting types. Some conversion bulbs allow MH light to work with HPS ballasts, and others let HPS work with MH ballasts.
Can you dim HPS lights?
These days, there are many brands and models of HID (HPS and CDM / CMH) grow lights that have the facility to be dimmed. It tends to be only the cheap ones (with magnetic ballasts) that do not. Nearly all digital ballasts have a control for dimming, and many also have a “boost” function too.
Do digital ballast use less electricity?
Digital ballasts are waaaaay more efficient. It’ll vary, depending on which units you compare, but typically digital ballasts use 3 – 4\% less energy. This doesn’t sound like much but, when you’ve got multiple grow lights on the go, the combined saving really cuts down your energy bills.
Can I use a MH bulb for flowering?
Due to the lack of red wavelengths in their spectrum, MH lights are not good at flowering plants on their own, though. This is the reason growers will use MH bulbs for vegging and HPS bulbs for flowering. Or even better, they use both bulbs simultaneously, for a much more complete spectrum.
Do HPS lights need a ballast?
Metal Halide (MH) and High Pressure Sodium (HPS) lights require a remote ballast to work. When building your own plant grow light, it’s important to match the ballast with the wattage of the bulb you will be using. You must also match the type of light (MH or HPS) you’re looking for with the ballast.
What is better for flowering HPS or MH?
Ironically, most HID grow light enthusiasts recommend using both MH and HPS grow lights. MH grow lights (metal halide) are suited best for vegetative growth and HPS grow lights are superior for flowering.
How far should 300w LED be from plants?
between 16-36 inches
During the flowering stage LED Grow lights should be located between 16-36 inches from the plant canopy. Moving the grow light closer will increase the light intensity which can maximize photosynthesis.
Can I use a 400W ballast with a 1000W bulb?
A 1000w ballast will limit the current to a value suitable for a 1000w lamp, which is more than twice that needed for a 400w lamp. Result: early death for the overloaded lamp (and possibly an explosion as well). You can do it with a 1000w bulb with a 400w ballast but not the other way round.
What is the purpose of a ballast on a light bulb?
The purpose of the ballast is to limit the current flowing through the discharge lamp, which has too low an impedance when operating to limit the current on its own. A 1000w ballast will limit the current to a value suitable for a 1000w lamp, which is more than twice that needed for a 400w lamp.
How much does it cost to replace a 400 watt light bulb?
Now if you substitute an LED bulb, that bulb will put out something like 8 times the light output per watt so you can replace the 400 watt bulb with something around 50 watts. Using a 50 watt LED, the cost will go way down to something like $.16 for 24 hours!
What is the heat rating of a 60 watt light bulb?
For a 60 W incandescent, the heat is 4 to 4.5 inches from the connector. For the CFL it is actually a lot closer. this is the reason for the reduction in the rating. In electrical terms, this is called the ‘derating curve’, and if the bulb were a LED, then it would be near 10W for the same size equipment.
