QUICK OVERVIEW

CTLite Logo - Cluster C4     Agent 939 LED FX
The Cluster C4 is designed specifically for home cultivators. Approaching the same industrial, energy-efficient features as our commercial fixtures, the Cluster C4's small frame helps you maximize small growing spaces and improve the quality and quantity of your harvests. Revolutionizing the horticulture lighting industry, our LED lighting solutions confidently stand out among competitors when it comes to design, technology, energy efficiency and service. The Cluster C4 Series has been developed by CTLite as a 1 on 1 replacement for outdated HPS (High Pressure Sodium) Lights and other lighting sources like LEC, HID and CMH lights. CTLite's mission was finding a way to manufacture a high quality, but low-cost LED module which offers a full spectral output for sig
nificantly reduced electricity costs. The LED module had to be purchaseable for the majority of growers that can not afford an expensive fixture, but still aim for high-end quality and want to enjoy the proven benefits of LED technology. After CTLite achieved their goal, the Cluster C4 has been sold to many distributors and is still rebranded under a variety of names at unreasonably high prices. But we decided to offer the new and opgraded Cluster C4
for a much lower and fair price so every grower can enjoy a qualitative full spectrum grow light, even boasting stronger 3000K and 5000K COBs with 2 additional Red and Blue LED-Clusters per COB, resulting in 6 LED-Clusters instead of 4 per COB.

Why choose the new Cluster C4 ?


Affordable and fair pricing; best value for money
Proven quality
Higher value crop harvests due to improved quality; increased terpene and cannabinoid levels
More usable light, less heat than HPS, improved grow room conditions. Grow all summer long!
● Full-spectrum LED
● For allround applications
● High return investment
● For full cycle grows (VEG to Bloom)
● Safe to use and easy to grow with


The Cluster C4 is the perfect solution for novice and experienced indoor home growers that want to start growing with a high quality and performance, but still affordable LED light. This Series has been copied, promoted and sold under a variety of brandnames (up to the present day) and not without reason of course, because the Cluster Series already proved itself to be a true HPS replacement and exceeds every other lighting source in its (price)class! 

As our regulations prescribe, we thoroughly tested the Cluster Series first and now its only fair to introduce them under the authentic name of the original manufacturer CTLite, and give them the credit they deserve. For their technology, partnership, dedicated team, patience and advanced manufacturing, just to name a few things. They have shown themselves to be one of the most professional, reliable and innovative partners in China and we cherish our long lasting relationship. Our professionals tested the Cluster Series for over 1,5 years before adding it to our collection, just to be absolutely sure what we are selling. Now we are proud and confident to finally offer the Cluster C4 so every grower can enjoy the benefits of LED technology, for a reasonable and fair price!
CTLite manufactures Greenception and IndoorLED's HPS Killer for example as well.

The Spectral output can be adjusted with 2 switches on top of the light: the Vegetative and Flowering mode.
The Vegetative mode offers a high Blue ratio with 440nm wavelengths and the Flowering mode offers a high Red ratio with 660nm wavelengths. The COBs offer additional Cyan, Green, Yellow and Orange wavelengths to complement the Spectrum so the C4 provides a Full Spectrum when both switches are on!


Cluster C4 CTLite - Spectrum Vegetative - Grow Agent 939 LED FX 2
Vegetative Spectrum

Blue wavelengths encourage vegetative growth and are essential in lighting for seedlings and young plants during the vegetative stage of their growth cycle, especially when “stretching” must be reduced or eliminated.  It also stimulates the production of secondary pigments which can enhance colors and is known to also stimulate Terpene (i.e. fragrance) production.

Cluster C4 CTLite - Spectrum Flowering - Bloom
Flowering Spectrum

Red light affects phytochrome reversibility and is the most important for flowering and fruiting regulation. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production.


Only a select few tell you the important metrics of a horticulture lighting system and PPFD  is definitely one of them! To some extend you could say: the higher the PPFD measurements, the higher the rate of photosynthesis and final yield will be. We recommend an average PPFD between:

100 and 300 μmol/m2/s for Seeds (for optimal conditions: additional CO2, ~400 ppm)
75 and 150 μmol/m2/s for Vegetative Cuttings (for optimal conditions: additional CO2, ~400-800 ppm)
300 and 600 μmol/m2/s for the Vegetative phase, including Mother plants (for optimal results: additional CO2, ~400-800 ppm)
600 and 1000 μmol/m2/s for optimal results during the Flowering/Reproductive phase, without additional CO2 (for amazing results: additional CO2, ~800-1400 ppm)
1000 and 1500 μmol/m2/s for phenomenal results during the Flowering/Reproductive phase WITH additional CO2, ~1400 ppm. Most strains can not thrive or even handle this photon flux density without supplemental CO2
