T8 LED tubes


T5 LED tubes


LED tubes: save up to 60% energy

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.

Energy savings and energy efficiency

Advantages of LED tubes

  • Save up to 60% energy. As they don’t need ballasts or starters, the consumption is lower.
  • Its lifetime is approximately 35.000 hours, 5 times longer than the lifetime of fluorescent tubes.
  • LED tubes offer a high luminosity. The more powerful and higher the LED lamp, the greater the luminosity.
  • Instant switching and flicker free
  • Variety of colours. Adaptable to the environment, you can choose between cool and neutral white and frost models.
  • Every tube has 2 years guarantee.
Good for you. Good for our planet

Good for you. Good for our planet.

  • LED tubes are 100% free from toxic substances, such as mercury or lead.
  • They reduce CO2 emissions by 86%. Safer to use, dump and recycle.

Differences between T5 and T8 LED tubes

LED tubes
LED tubes


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.

T8 tubes

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

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.

Replace a fluorescent tube with a LED tube?

If you want to connect this kind of tubes you have to rebuild the wiring: Remove the starter and the ballast, plug directly both wires of the electricity network into the two pins of the end of the LED tube.

How to replace a fluorescent tube with a LED tube?

Perform the following steps

Step 1:

Turn off the electricity to the fixture.

Step 2:

Remove the fluorescent tube, the ballast and the starter.

Step 3:

Connect the PHASE to one end of the bulb socket and
connect the NEUTRAL to the other end of the bulb socket.

Step 4:

Check whether the tube is working properly…YOU DID IT!

Where can you install LED tubes?

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.

Features of LED tubes

Explore the features of LED tubes.

Power (W)

Electrical power is the result of dividing the energy consumed by the time it takes to be consumed. Its unit of measurement is watts or kilowatts, "W" or "kW".

Colour temperature – Kelvin (K)

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.

Light source – Colour temperature (Kelvin)

Beam angle

The beam angle of a lamp is the angle at which light is emitted. The Beam angle is the angle between the two directions opposed to each other over the beam axis for which the luminous intensity is half that of the maximum luminous intensity. The viewing angle choice also affects the LED output intensity.

Number of LEDs

Another important aspect of a LED lamp is the quantity of diodes by which they are composed. In many cases, diodes are positioned along the surface of the tube and they are supported by a printed circuit board. The light distribution depends on the number of diodes. A tube with 400 diodes won’t have the same performance as tube with 270 diodes; the first one will achieve a more uniform light distribution.

Common questions about led lighting

What is a LED?

LED (Light Emitting Diode) is a light source which perfectly fits in an electric circuit. As LEDs light up thanks to the movement of electrons in a semiconductor material, LEDs don’t burn, don’t heat and don’t use dangerous substances.

How much money can I save?

  • Savings will vary depending on the case, but, in general, we can guarantee:
  • 60% more efficient than low-consumption bulbs
  • 90% more efficient than traditional and incandescent bulbs
  • Between 60% and 90% less heat emitted
  • They last 6 to 20 times longer than a traditional lighting
  • Savings in electricity, time and money

Quantity, quality and colour of Led Bulbs

LED Bulbs,as conventional bulbs, have a wide variety of colours that can be from 2.700K to 6.500K.
Colours are classified by: warm (2700-3500K), neutral (3800-4200K) y cool (4500-5300K). Moreover, LEDs allow a colour rendering index 95%, that it’s to say, you can obtain almost every colour.

Which power has a LED Bulb?

There are LED bulbs with different characteristics and powers. You can find a wide range of Bulbs with powers that can be from 4W to 275W.

Do they require professional installation?

No, they don’t. LED Bulbs are just like any other conventional bulb. No extra installation required.

How long should a led bulb last approximately?

LED Bulbs last approximately 50.000 hours. LedThink gives you two-year guarantee in all our products against any manufacturing defect.

How long does it take to recover the investment?

It will depend on the use of the installation. Taking a parking as an example where lights can be switch on for 24 hours, the investment will be recovered within 2 years. Taking street lighting as an example, the investment would be recovered within 4 years.

Have these Bulbs a guarantee?

Yes, every LED bulb has a guarantee. The guarantee period will depend on the type of bulb or brand. LedThink gives you two-year guarantee in all our products against any manufacturing defect.
