T5 and T8 LED tubes (light-emitting diode) replace conventional fluorescent tubes. The advantages of LED tubes are very important: they last up to 50.000 hours, they use less energy, they work without ballasts and they contain no mercury.
LED technology allows you to save up to 60% energy, these LED tubes last up to 5 times longer than traditional tubes and they have 2 years guarantee. Discover what LED lighting can do for you and for your pocket.
The T used in front of the number indicates that the fluorescent spot is a tube. The numeral appearing after the letter indicates the diameter of the tube measured in fractions of an inch. example, a T5 has a diameter of 5/8 inch; a T8 has a diameter of 8/8 inch and a T12 has a diameter of 12/8 inch.
T5 and T8 LED tubes (light-emitting diode) replace fluorescent tubes which exist in the market today.
The LED tube par excellence is the T8 tube, it’s the most common tube in offices, corridors, hospitals, car parks and so on. When we replace traditional luminaries with LED tubes, we should remove the starter and the ballast to avoid the unnecessary energy consumption. T8 LED tubes have a directional light.
T5 tubes are shorter and they don’t meet standard devices. For example, a typical T5 has 46 inches (115 cm) instead of 48 inches (120 cm) such as T8 tubes. There is a set which allows you to adapt T5 tubes in T8 tubes devices. You will be able to save money because T5 tubes have a longer lifetime by producing a high luminosity with a low voltage.
They have a diameter of 15mm and the replacement is very simple. T5 LED tubes last up to 10 times longer than a normal fluorescent and as they don’t need ballast or starter, its energy efficiency are higher. T5 LED tubes have a directional light.
Even though T5 tubes are smaller than T8, they produce approximately the same amount of light. T5 tubes have a luminosity of the surface bigger than the luminosity of T8 tubes. That’s why; the glare can be a problem, specially with high performance bulbs (5000 lumens). However, this glare can be mitigated with the use of grids or diffusers.
They can be installed in places which require almost 24 hours of light: car parks, hotels, universities, high schools, offices, comercial centres, shops and so on.
Colour temperature could be defined as the predominance of certain colours in WHITE lighting. In this way, white can be modified towards amber or towards blue. Colour temperature is measured in Kelvin and it is only applied to white lights. All other colours don’t have a colour temperature. For this reason, white lights, which have a predominance of amber, will be called warm lights and white lights, with a predominance of blue, will be called cool whites. When we are in a room lit by a warm light, we feel like we are in a warm and comfortable environment. On the contrary, if we are in a room lit by cool lights, we feel like we are in a cool atmosphere.
The colour temperature is approximate since there are many factors which can produce changes. Unless you have a thermocolorimetre, you can’t know exactly the colour temperature of your luminaire.
