Five main types of aquarium lights
It is a misconception that when setting up an aquarium, any lighting fixture will do. This is in fact not the case; proper aquarium lighting is essential to maintaining a healthy aquarium and healthy fish.
Different types of aquariums have different lighting needs. You will need to do some research into the types of fish you intend to acquire and what their specific needs are. An important factor is whether or not you will be keeping freshwater plants or saltwater reefs. The amount and type of aquatic light you will need is dependent on these factors.
There are five main types of aquarium lights. The five main types are regular fluorescent lights, compact fluorescents, high and very high output fluorescents, metal halides, and Light Emitting Diodes (LED's aquarium lights). Each of these lights serves different purposes for aquarium lighting.
Regular fluorescent bulbs are acceptable for most fresh and saltwater fish. You will want choose a light to fit the hood on top of your aquarium. A full spectrum fluorescent is a good idea to be sure that your fish are absorbing all of the wavelengths necessary to keep them healthy.
If you intend to have live plants in a freshwater aquarium, different lighting may be necessary. Plants need certain wavelength light rays in order to produce energy through photosynthesis which they depend upon to survive. Each type of plant will have its own lighting needs. You will have to research the plants for specific directions. A general rule of thumb for plant aquarium lighting is 2-5 watts of light per gallon of water in your aquarium.
Saltwater aquariums with living corals or other non-fish organisms will need very special lighting. These tanks require high or very high output fluorescent bulbs or metal halides. These tanks need 4 to 10 watts of light per gallon of aquarium water. This classification of aquarium lighting tends to produce heat which must be treated properly to prevent overheating of your aquarium. Special fixtures with built in fans may be necessary to disperse the extra heat. In some cases, you may even need a chiller to keep your water and an appropriate temperature for your fish.
Another important part of lighting your aquarium is the day/night cycle. An electric timer is recommended to keep your fish on a regular schedule and so as not to stress them. An LED moonlight simulator may be obtained for particularly delicate species to emulate the soft wavelengths given off by the moon in nature. The best way to determine whether or not you will need this addition to your aquatic lighting system is to thoroughly research the fish you intend on purchasing.

three red lights and an orange power supply light?
My xbox has the very common RROD with three quadrants red. The power supply light is orange. Microsoft told me that all I needed was a new power supply. Well I got one that is compatible (175w) and still my xbox has the red ring of death. If it was hardware failure my power supply would have a red or green light. What is wrong with my xbox?
You probably have a generic hardware failure and the arabs at xbox support are just reading off a computer screen to tell you what to do. They don't know anything about electronics and they get paid less 25% of what the techs in Redmond WA make in an hour.
Anyway here are some instructions to get your secondary error code from your xbox. With your secondary error code you can better determine what is wrong with your xbox. You don't need to take your xbox apart so this is perfectly safe.
-First turn on the xbox and wait for the 3 red lights to appear
-Then press and hold the sync button while pressing the eject button, the lights flashing will change and blink faster, write this number down this is the first number in the 4 digit error code.
-Press and hold the sync button while pressing the eject button again, the lights will interrupt and then flash fast again, this is the second number in the 4 digit error code.
-Press and hold the sync button while pressing the eject button for the 3rd time, the lights will change and keep blinking fast, this is the third number in the 4 digit error code.
-Finally press and hold the sync and press the eject button one last time to get the fourth digit in the error code.
-Do the button sequence one last time and the 3 red lights will return.
You can go though this as many times as you want to make sure you wrote down the right error code. Here's how to interpret the numbers
1 red light = 1
2 red lights = 2
3 red lights = 3
4 red lights = 0
There are no 4's in any error code. If you wrote down 4142 the error code would actually be 0102.
Now you can enter your 3 red light secondary error code here

This guide will also tell you how to fix the error, i'll leave that up to you. If your xbox is with in 3 years of the mfr date on the back then you have an extended warranty and can have your xbox repaired for free.
I don't see why customer support would tell you it's your power supply without proper testing techniques. Any xbox power supply that plugs in to your xbox will work, microsoft designed it that way. I use a 203W to test all of my repairs, the 203w power supply will work with any 360 besides the new slim.
If you have any other questions feel free to contact me via my yahoo answers profile.

How to choose the suitable grow light for your greenhouse?
There are many kinds of Grow lights for your chosen in market, that might be a headache to a new grower when make a choice. I list all of them below that hope to make clear:
The least expensive lights to purchase cost around $30. These incandescent lights work well for specific plants where the light is placed a minimum of 24" from the plant. These lights get extremely hot so they must be used with care. Spot grow bulbs, color corrected incandescent lights, install easily and are good for use with a specific plant or a small grouping of plants. Most spot incandescent bulbs last less than 1,000 hours. Some light fixtures come with a clip handle so you can put them exactly where they're needed.
Florescent grow lights are a common choice for homeowners. Florescent lights are reasonably energy efficient and relatively easy to install. A typical florescent bulb will last approximately 20,000 hours. Florescent light is typically on the blue end of the spectrum. Blue light encourages bushy compact growth which makes them perfect for seed starting. The blue light is also cool to the touch making it possible to place lights within just a few inches of the seedlings.
New full-spectrum florescent lights provide the red spectrum as well to encourage blooming. Combining the lights in a fixture makes for even, all around growth. The next generation in florescent lighting includes the new T-5 lights. These new lights have extremely high output but are energy efficient and long lasting. The T-5 lights triple the light output of normal florescent lights without increasing the wattage. Plants absorb a high percentage of T-5 lighting because the fixtures function well very close to plants. High output bulbs require a high output fixture to operate, so the bulbs and normal florescent fixtures will not work together.
Some commercial growers use High Intensity Discharge lights because they have extremely high output and cover a wide area. HID lights hang high above plants (hanging height determined by the wattage) so the light works well for large growing areas. Operating HID lights require a ballast to deliver power to the lamp and fixture for the light. Most fixtures have a reflective hood which directs light back towards plants. HID lights emit high heat, so they must be placed away from plants to avoid burning the leaves. There are two types of HID lights, Metal Halide and High Pressure Sodium.
Metal Halide produces blue light that most closely resembles natural light. This would be the preferable light if used as the primary lighting because plant growth most closely resembles plants grown outdoors. This type of lighting is excellent for areas that do not get natural sun.
The second type of HID lighting, High Pressure Sodium, is excellent for supplemental lighting in a greenhouse because the red light enhances flowering. The bulbs also last substantially longer than Metal Halides. Used as supplemental lighting, the orange-red light does not create leggy growth. It is interesting to note that plants do not appear as healthy under the reddish light as the blue because our eyes do not adjust well to the color. High Pressure Sodium bulbs have a long life; however, they should be replaced according to manufacturer's instructions. Bulbs continue to light beyond their useful life, however, the energy draw increases dramatically and the output lowers significantly.
Metal Halide and High Pressure Sodium lights generally do not use the same fixtures, however, some fixtures are convertible. With convertible fixtures, bulbs swap easily. A simple flip of a switch converts the fixture after changing the bulb. This is a good option for serious growers who want the benefits of compact growth, blooms and energy efficiency. The start up cost is not insignificant. However, the combination offers a tremendous amount of control in the greenhouse.
The newest type of grow lights use LED technology. One major advantage to the LED grow light is the small size. LED grow lights are only a few inches in diameter and are easy to mount. In some greenhouses, LED grow light may be the only practical light option. Hanging most grow lights requires a strong greenhouse structure and a place to hang the lights. LED grow light weigh a fraction of other lights and are easy to configure where needed. According to LED manufacturers, LED grow light maximize blue and red light to provide and excellent balance for plants. They do not have much green-yellow light. Since humans see green-yellow light best LED grow lights appear dim to our eyes. And the most important advantage is that LED grow light is green technology which don't contain any harmful substance like HID or other traditional grow lights, and it can save 70-80% electricity bill than using HID lamp. This is newest technology used for plant growing now and becoming more and more popular.
