SANlight Q4W

Highly efficient LED grow light for grow tents

Developed from all the experience gathered by SANlight in recent years, the Q4W light combines all the benefits SANlight has come to offer with new features that make it more convenient and future-proof.

The highest efficiency, perfect light control and passive cooling are complemented by some new features.

By using a Y distributor (available as an accessory), you can operate up to 7 Q4W lights on a household power outlet.

The Q4W is suitable for the most common indoor grow tents. For Example: 60x60cm (2x2ft) and 100x100cm (3.2×3.2ft)  tents can be properly lluminated with a minimum amount of modules.

The secondary optics (lens) have a precisely defined 90° beam angle. As a result, the light is distributed homogeneously over your cultivation area and the losses due to light scattering are minimized. The wide radiation pattern also helps you to cultivate high-growth indoor plants with limited height.

The breeding of fruit-forming short-day plants indoors without daylight, in particular requires high light intensities (PPFD). The broadband light spectrum of the Q4W not only promotes the maximum photosynthesis rate, but also helps the plant regulate its hormone balance. Better yields and healthier plants are the result.

As a Q4W user, after several years of operation, you can easily and cost-effectively upgrade your light to a state-of-the-art technology by having the LED modules replaced by a certified retail partner. This is done in no time at all. It not only saves resources, but also your money.

With The Q4W, SANlight has created a product that is versatile and leaves nothing to be desired.

In summary, I can say that I have understood that by using these LED lights, the cultivator is provided with illumination requirements that were up till now not possible in the “dark months” of the year. The practice test has shown that not only can these LED lights replace the existing HPS lamps without any disadvantages, but they are also able to equip you with completely new opportunities.

In our nursery, we cultivate a variety of crops, even ones that are seldom cultivated at this latitude. We will use LED lights for many of these cultures in the future, to positively influence quality and flowering times. In addition, arguments such as improved light distribution and less shade as a result of a slim lamp design, clearly speak for these LED lights.
