In order to understand the differences and the uses of the spectra available in the Todogrowled catalog, we bring you this short guide that will guide you when choosing the color temperature that best suits the needs of your crop.
Before presenting the guide, we will clarify two fundamental concepts to understand this topic:
When we talk about 3000k, 3500k or 4000k, we are talking about color temperature, which is nothing more than the predominance of one color or another in white light. It is measured in degrees Kelvin (k) and the lower the number, the warmer light (more similar to, for example, sunset light) and the higher that number is. a cooler light (more like, for example, the light of noon on a clear day). From 5000 K they are said to be cold colors, while at lower temperatures (2700-3000 K) they are considered warm colors. To speak of cold or warm light is to speak of tonality. The color temperature has nothing to do with the heat emitted by the light source, in this case the LED.
The CRI is an independent value of the color temperature, that is, of the color of the light emitted by the source. The range in the color rendering index is from 0 to 100, with 100 being the “perfect” value. The higher the CRI, the more similar to sunlight the light emitted by that source will be and it will have a spectrum very similar to the light absorption graph of plants.
Once we are clear about these two concepts, we can apply them to our cultivation:
Except for TGL STAR 60 6500 White, all TGLs are full spectrum, that is, all lamps will serve you for the complete growing cycle, but some are more suitable than others if we only want to use them in growth or flowering. We will see the more specific characteristics of each option below:
3000K - For full cycle with enhanced flowering:
Indicated to enhance flowering and achieve better results in the final phase. It is the most orange light. The chip used is the Citizen CLU48 CRI 97.
3500K - If you are looking for a complete spectrum that enhances the crop from start to finish:
4000K - If you are looking for fast growth and enhanced flowering with reds:
- 6500K - For growth only:
This spectrum is the whitest of all those in our catalog and, due to the large amount of blues it has, makes it ideal for growth, quickly achieving compact, strong and robust plants.

The new Evolution series is the improved version of the usual TGL 220.
New Evolution Series features:
- - New MeanWell XLG driver (up to 260w)
- - Larger growing area (up to 140 x 70)
- - With external dimmer included
Unlike the TGL 220 Classic, equipped with CREE LEDs with 3500º K spectrum for full cycle, TGL 220 Citizen offers you two more specific options (also both for full cycle):
- The 3000º K spectrum has very few blues and a peak in reds at 660nm that enhances flowering
- The 4000º K spectrum has a large amount of blues that improves the vegetative phase.
If you want to illuminate large spaces during the complete cycle that enhances a specific phase of the crop, TGL 220 Citizen is your luminaire.
|3500º K||360 g||250 W||140 x 70|
- · New MeanWell XLG driver (up to 250 W)
- · Larger growing area (up to 140 x 70)
- · With external dimmer included
The new Evolution series is the improved version of the usual TGL 220. Now, with this more powerful model, you can cultivate up to 140 x 70 thanks to the new MeanWell XLG M-ABOL driver and its 250 Watts of power. If you want to use your TGL 220 Evolution in smaller spaces or with better electricity consumption, we have added an external dimmer as an extra that you can easily install in your luminaire, which will allow you to regulate the power according to the needs of your crop. This addition makes the new 220 Evolution super versatile equipment that adapts to different sizes of cultivation and consumption.
- For 120 x 60 cm or 140 x 70 with 1 single luminaire from seed to harvest. With 2 units you can illuminate in the most efficient way a space of 1.20 x 1.20 cm or 1.40 x 1.40.
- 4 COB CREE Cxb 3070 LED light points with great light penetration with which you will get buds even in the lowest parts of the plant and a very short internodal distance.
- 2 integrated Sunon fans, which help keep the closet cool and move the air inside.
If you want to illuminate large spaces with the best quality / price ratio, TGL 220 Classic Evolution is your luminaire.

|3500 K||140 g||104,2 W||80 x 80|
The big sister of the TGL STAR 60. This is your luminaire if you are looking to illuminate larger spaces (90 × 90 cm) with a single unit that can be used for a complete cycle. You can also combine them to cover larger spaces with several independent points of light, for example 4 are ideal for 1.20 × 1.20 cm and with 5 you could cover up to 1.50 × 1.50 cm.
Equipped with a COB CREE Cxb 3590 LED, which is 10% more efficient than the 3070, its great light penetration allows to achieve buds even in the lowest parts of the plant and a very short internodal distance.
If you want to illuminate a space of up to 90 × 90 from seed to harvest and achieve a high production with minimal electricity consumption, TGL STAR 100 Classic is your luminaire.
|3 K/ 4 K||75 g||55 W||60 x 60|
TGL STAR 60 CITIZEN is designed to illuminate a small space during a complete cycle, enhancing a specific phase of the crop.
Unlike the TGL STAR 60 Classic, this Citizen version offers you 2 more specific options (both being equally for full cycle): The 3000º K spectrum offers very few blues and a peak in reds at 660nm that enhances flowering. The 4000º K spectrum offers a large amount of blues that enhance the vegetative phase.
Equipped with a Citizen CLU48 CRI97 COB LED, its great light penetration allows to get buds even in the lowest parts of the plant and a very short internodal distance.
Combine several units in larger spaces, for example, with 4 TGL STAR 60 Citizen you could illuminate 1m² with 4 independent light points, adjustable in distance and height depending on the needs of your crop and your space.
|3500º K||75 g||55 W||60 x 60|
TGL STAR 60 Classic is designed to illuminate a small space of up to 60 x 60 cm from seed to harvest thanks to its full spectrum of 3500º K.
It is an affordable device both in price and consumption with surprising performance and efficiency for its size. Equipped with a COB CREE Cxb 3070 LED, its great light penetration allows to get buds even in the lowest parts of the plant and a very short internodal distance.
It also stands out for its versatility, since you can combine several units for larger spaces, for example, with 4 TGL STAR 60 Classic you could illuminate 1m² with 4 independent light points, adjustable in distance and height depending on the needs of your crop and your space.
If you have a small tent and you want to achieve a large production with the least electrical consumption, TGL STAR 60 Classic is your luminaire.
