Frequently Asked Questions

Can I change a high pressure sodium fixture to a metal halide and vice versa?

Yes you can. You will need to change out the ballast, capacitor, ignitor and lamp. However, there are several cautions that must be taken: the metal halide wattage must be within the fixture limitations; the socket position may need adjustment; the reflector may be different or the ballast strapping may not fit properly. Please contact the factory for a specific product.

What is the difference between High Pressure Sodium and Metal Halide?

Frequently Asked Questions - Greentrees Hydroponics
The difference between these two types of HID (High Intensity Discharge) lights is the color spectrum that is emitted from each. The High Pressure Sodium bulb emits light that is concentrated in the red to yellow side of the spectrum and are weak in the blue-violet end. While the Metal Halide bulb emits light that is very balanced and contains all the energy peaks at wavelengths of the visible spectrum.

GreenCoast Hydroponics - FAQ
Although High Pressure Sodium and Metal Halide are both types of HID (High Intensity Discharge) lights, they emit different color spectrums. High Pressure Sodium bulbs emit very bright light that is concentrated in the red to yellow side of the spectrum and weak in the blue-violet end. Metal Halide bulbs, by contrast, emit a very balanced light, which contains all the energy peaks of the visible spectrum. Both types of lighting have their place in an indoor growing environment.

What type of light is better, High Pressure Sodium or Metal Halide?

GreenCoast Hydroponics - FAQ
First, what type of natural light are you working with? When supplementing natural sunlight, use a High Pressure Sodium bulb to extend daylight in the early spring and fall. You can also use them on low light cloudy days. When no natural light is available at all, a Metal Halide bulb is most frequently used, , which is a very wide spectrum bulb perfect for indoor growing. Halide lights are excellent for vegetative growth for leafy plants like lettuce and basil.

What is the life cycle of Metal Halide and High Pressure Sodium lamps?

GreenCoast Hydroponics - FAQ
Metal Halide lamps should be changed at least every 6 to 12 months if you're burning them 18 hours per day. High Pressure Sodium bulbs, burned at 12 hours per day, will last between 6 months and a year and a half depending on the bulb.

What is the difference between Metal Halide and High Pressure Sodium lighting systems?

Hydroponic FAQ
Although both types of lighting systems appear very similar, the main difference becomes readily apparent when you turn them on. A Halide system emits a balanced white light similar to the spectrum of sunlight. This type of light promotes vegetative growth. A Sodium system emits a light spectrum and gives off a warmer colored light. This type of light helps stimulate a plant to produce flowers and fruit.

What is the best light to use, High Pressure Sodium or Metal Halide?

Canadian Xpress - Fusion Nutrition Specialists
In our controlled trials, we found that High Pressure Sodium (versus Metal Halide) when used for an entire crop cycle, slightly but noticeably out performed Metal Halide. We have also found that High Pressure Sodium gives a marginally better yield if it used for the bloom phase and the Metal Halide performs slightly better during growth. Our results would not justify purchasing both the lights for growth and bloom but this may not be the case with all species and strains.
Related Questions

Why do people use a Metal Halide for vegetative growth and High Pressure Sodium for flowering?

GreenCoast Hydroponics - FAQ
There are a couple of reasons growers switch between bulbs during different stages of plant growth. First, Sodium bulbs can make some plants grow "leggy" and stretched out due to the high yellow to red spectrum they give off. Halide bulbs tend to keep plants "tighter", with less space between internodes.

Why do people use Metal Halides for vegetative growth and High Pressure Sodium's for flowering?

Frequently Asked Questions - Greentrees Hydroponics
Many people switch between bulbs for different stages of growth for a couple of reasons. First of all, Sodium bulbs have been known to make some plants grow leggy and stretched out because of the yellow to red spectrum that they give off. Metal Halides tend to keep these plants tighter with less space between internodes. So some growers use the Metal Halide lights during vegetative growth to keep the structural growth of the plant nice and tight.

Can I change the insert on my Seamaster from blue to stainless steel, or vice-versa?

Omega FAQ - TimeZone
Yes you can, but it is a tricky job. Most watch makers will tell you that you should buy a new bezel, because if the insert gets bent while installing the new one, it will put a permanent white line on that bezel insert. If you want to change the color insert, send your watch to an Omega service center near you.

What are the advantages of earmuffs over earplugs and vice versa?

Frequently Asked Questions
Earmuffs are easier to use correctly, and therefore provide attenuation that is much closer to the laboratory derived NRR. Earplugs are hard or sometimes very hard to insert correctly, and therefore often do not provide the same attenuation in the field, as they do in the laboratory. This is the reason that NIOSH recommends different de-ratings for earplugs and earmuffs. You can read more about this subject by clicking on this link.

How can an MSVC program call a MinGW DLL, and vice versa?

MinGW - Frequently Asked Questions
Assume we have a testdll.h, testdll.c, and testmain.c. In the first case, we will compile testdll.c with MinGW, and let the MSVC-compiled testmain call it. You should use gcc -shared -o testdll.dll testdll.c \ to produce the DLL and DEF files. MSVC cannot use the MinGW library, but since you have already the DEF file you may easily produce one by the Microsoft LIB tool: lib /machine:i386 /def:testdll.def Once you have testdll.lib, it is trivial to produce the executable with MSVC: cl testmain.

Q: Why would someone choose a metal seal system over an elastomer seal system and vice versa?

MDC Vacuum Products. - Products FAQ'S- Flanges and Fittings
A: The main reason for choosing a metal seal system is in the level of vacuum that can be achieved. Elastomer seals allow air and other gases to permeate through them faster than through copper, and therefore are restricted to high vacuum applications. Metal seals have lower rates of permeability and can be baked to higher temperatures than elastomers, and are therefore used for ultrahigh vacuum applications.

Do metal halide lamps have special cooling requirements?

UV Curing Lamp FAQ
Gallium and multi-spectrum lamps have cooling requirements fairly equivalent to mercury lamps. Special care is required for iron lamps. If an iron lamp overheats, the iron will irreversibly become part of the quartz tube. This will not cause lamp failure but you will lose the iron portion of the UV spectrum.

Why Are These Metal Halide Kits More Expensive?

DIY Video Projector FAQ - DIY Projector Company
You may have noticed that our metal halide light kits are more expensive than other models available online. The reason is that our light sources utilize HQI and electronic ballast technology. Less expensive kits use core-and-coil technology, which causes the annoying "buzzing" sound that you are used to in parking lots.

What are the advantages of a CF200 drysuit vs. a FLX50/50 drysuit and vice versa?

DUI - Diving Unlimited International Virtual Customer Servic...
The patented crushed neoprene used for the CF200 is the most durable material available for drysuits. It is so tough we use it to make kneepads and boots for our other suits! Given this ruggedness the material is heavier than other fabrics. Although totally dry inside, the outer nylon layer absorbs water making it heavier still when wet, and requires about as long as a wetsuit does to dry.
