The standard T5 lamp was developed in Europe several years ago, and then introduced to the North American market in 1996. In 1998 t5 HO was introduced in North America. It offers about twice the lumen output in the same length.
I will assume you mean fluorescent tubes They are different caps
Since T5 bulbs are shorter than their T12 or T8 counterparts, they do not naturally fit into fixtures designed for T12 or T8 bulbs. Luckily, there are companies that offer retrofit kits that can allow you to use T5 bulbs in fixtures not designed for them. A company called Lumiversal makes two different types of these retrofits. These retrofits are a great way to save money and electricity plus you can rebates and incentives from your utility providers to help cover the cost.
Radio fuse
250W tungsten halogen gives around 10,000 lumen. 2 x 39W T5 fluorescents gives a total of between 4,000 to 6,000 lumen.
LED lighting is slowly filling the Home Lighting and Business Lighting market place with such innovative products as LED T5 and LED T8 Tubes, Flexible LED Lighting, and LED Down Lighting.The list is long and this is good, at least in my opinion.So you could find everything from above in this website. Take care.
T5 bulbs technically will last for about 20 000 hours. That's over 2 years if they were on continuously. However, if you are using them for an aquarium, they should be replaced every 10-12 months.
The three types of hot-cathode fluorescent lamps are T12, T8, and T5. T12 lamps are the oldest and largest, T8 lamps are more energy-efficient and commonly used in commercial applications, and T5 lamps are the smallest and most efficient, often used in task lighting or compact installations.
High output T5 fluorescent is probably the best bet. You can get various 4 foot fixtures at www.bigalsonline.com. Here's a link:
A T10 tube light is a type of fluorescent light bulb that is 10/8 inches (25.4 cm) in diameter. It is commonly used in commercial and industrial settings as a direct replacement for T12 or T8 tube lights. T10 tube lights provide efficient and long-lasting lighting for a variety of applications.
The simple answer is yes, but it really depends. What type of corals do you plan to keep? Will you be only stocking softies, or will it include some LPS and SPS species? The tank dimensions, depth, bulb density, and bulb color also have an effect. I would suggest reviewing some of the numerous reef forums to learn more. Also, make sure that they are HO T5 and not NO T5; only the HO T5 bulbs have the intensity to maintain corals.
I found that my lights were pointed very low on my T5. when i took apart the projector lens i saw there is a piece of metal blocking the beam from pointing higher. I just bent this beam away from the lens a bit to allow light to be projected upward more. they are very bright now. the question is... how legal?
In the off position push the switch in and turn to parking lights position, then just pull out. John
