Are TGL lamps suitable for growth and flowering?

We have luminaires of different spectra for different needs, from just growth (B-Spec and 6500ºK spectrum) to full cycles (3500ºK) or full cycles with enhanced phases (R-Spec spectra, 3000ºK, 4000ºK, etc.).

Do I have to do some kind of installation to start growing with TGL?


All TGLs are plug and play - plug and grow. In case you want to assemble or customize your luminaire, we also have the HLG 135 and HLG 260 luminaire kits.

Do they plug directly into the power?

Yes, each luminaire has transformers or drivers that allow them to be plugged in like any other domestic electronic product.

Do TGLs generate a lot of heat?

No, each model of luminaire has been designed in such a way that they cool down without the need for any external device. For example, TGL STARs have a passive heatsink that allows optimal cooling of the LED. In the case of the TGL 220 Evolution, the 2 Sunon fans, powerful and silent, dissipate the heat produced by the LEDs. The equivalent in sodium lamps would be 80% less for a 400W model.

What does passive dissipation mean?

It means that you do not need a fan or other cooling system other than the one included in the luminaire. In this way no noise or extra expense will be generated.

Do I have to make any changes to go from growing to flowering?

To change phase it is only necessary to change the photoperiod, that is, the hours of light on and hours of light off. An indicative combination could be 6 pm-8pm. on in growth and at 12 h. lit in bloom.

Is it necessary to change LEDs every year?

No, the lifespan of our LEDs is about 5 years of continuous cultivation. Once this time has elapsed, the LED should be checked and checked if it has lost efficiency.

Do the luminaires need any maintenance?

We recommend cleaning the luminaires and fans (if they have them) once per crop. The best time is after the cultivation is finished. They can be cleaned with a slightly damp cloth or by blowing air.

Are the flowering times the same as with sodium lamps?

Our growers have noticed a shorter flowering time in their crops, which means enjoying before our harvest.

What growing area can I cover with TGLs?

With the TGL you can cover any growing area.

From very small spaces - thanks to the characteristics of the TGL STAR for example - to large growing areas. For example, the TGL 220 Evolution models allow long and narrow crops and would be perfectly suited to 0.6m × 10m crops allowing direct access to all plants.

By combining the TGL STAR, the lighting can be designed for spaces in «L», squares ... Each TGL STAR 60 covers a maximum flowering area of 0.5 × 0.5 meters, reaching 0.6 × 0.6 meters in growth. . The TGL 220 Evolution cover a flowering area of 1.3 × 0.65 meters while in growth the area expands to 1.4 × 0.7 meters.

What production can I expect with the TGL?

We monitor thanks to the collaboration of many of our customers and the average is generally 1.4 grams per watt (g / W). This amount is an approximate average, since it is possible to reach 1.7 or 1.9 g / w with optimal production.

What maximum production can I have per m²?

Per square meter, under optimal conditions around 700 g can be harvested. It is not necessary to cover the space with luminaires: with about 400-500 W we obtain the highest productions. To have a normal harvest per m² - between 300 and 400 g - it is enough with about 240 W of our TGL-STAR models for example.

On models with fans or active dissipation, is the noise "annoying"?

In our designs we have selected silent components to avoid annoying sounds. We use Sunon fans to ensure a high air flow with minimal noise. The TGL 220 Evolution models are very quiet, with an almost imperceptible fan sound.

For guidance, four fans produce a lower sound than 1 clip fan used to move the air inside the cabinet.

What kind of LEDs do the TGLs mount?

At the moment our TGL luminaires have CREE LEDs —3500º K and 6500º K— and Citizen —4000º K and 3000º K—. In the case of HLG luminaires, the LEDs will be different Samsung, Osram or Seoul models, depending on the spectrum.

Our R&D department is in charge of continuously searching for options or alternatives that improve current models in order to offer the best grow lights on the market.

Can I combine the TGL with other luminaires?

Yes, you can add our luminaires to improve your set up - increasing production or growing area - or to progressively change old lights in large spaces.

What distances should I follow for growth and flowering?

There are no fixed rules regarding distances - although you can find a specific guide table for each luminaire model in the corresponding product sheet in our store - but we can give some basic indications: We recommend placing the luminaires as far apart as possible from the plant at the beginning of the cultivation process, without allowing the plants to stretch much or "glean" so that they gradually approach the light. Putting them too close can cause stress to plants in the first weeks of life. In growth they would be about 60 cm and in flowering about 25 cm.

Are there differences between the types of substrate used?

You will achieve maximum performance in hydroponic or aeroponic crops, although the most common is to grow in soil and / or coconut, in this case we recommend a well aerated and loose substrate, as with any lighting fixture.

They have a guarantee?


Yes, all our luminaires —TGL— include a 2-year warranty and in the case of HLG luminaires it is extended to 3 years. Also, being in Spain — specifically in Asturias — the procedures are much faster.

What does it mean that the TGL 220 Evolution models are dimmable?


It means that the power can be lowered and raised according to the needs of electrical consumption and space. They come equipped with an external dimmer with a thread with which you can easily and comfortably raise and lower the intensity of your luminaire

Is COB or Quantum Board better for me?

COBs: Acronym for Chip On Board. This type of LED stands out for its great light penetration, reaching the lowest parts of the plant. This translates into less internodal distance and higher yields. In COBs the convection is centralized, even forced, with a powerful heat sink. It has few points of light and it is easier to remove to fumigate, providing more space available inside the cabinet.


Quantum Board: SMD LEDs are the latest generation in R&D of horticultural LEDs. They are distributed throughout a larger area, similar to that of the crop. It uses a larger surface area on the plants than COBs. The light distribution is more homogeneous.

What is the difference among the Evolution Series?


TGL 220 CLASSIC EVOLUTION, our traditional TGL, equipped with Cree 3070 and 3500ºk, the best value for money to grow from seed to harvest.

TGL 220 PLUS EVOLUTION, formerly TGL 220/3590, The improved version of TGL 220 Classic. Its main difference lies in the chip with which it is equipped: The CREE Cxb 3590, which is 10% more efficient than the Cree 3070 of the TGL 220 Classic: It produces a little more and consumes a little less. If you want to illuminate large spaces with the highest efficiency and at the best price, TGL 220 PLUS Evolution is your luminaire.

TGL 220 CITIZEN EVOLUTION, equipped with Citizen CLU48 and now also in 3000ºK. Unlike the TGL 220 Classic and Plus, equipped with CREE LEDs with a 3500º K spectrum for full cycle, this Citizen version offers two more specific options (both being also for full cycle): The 3000º K spectrum has very few blues and a peak in the reds at 660nm that enhances flowering. The 4000º K spectrum has a large amount of blues that enhance the vegetative phase. If you want to illuminate large spaces during a complete cycle that enhances a specific phase of the crop, TGL 220 Citizen Evolution is your luminaire.

What is the difference between the Citizen and the Classic?


The main difference in the case of our luminaires is the spectrum available. In the case of the Classic, the LED is a 3500º K CREE that is used for a complete cycle without enhancing any specific phase, whereas the Citizen — named for their LED — are available in 3000º K and 4000º K, to enhance the phases. of flowering and growth respectively.
