Sanlight EVO 4 Set 120x120 Pack: High-Performance LED Lighting, Turnkey Solution
The Sanlight EVO 4 Set 120x120 Pack is the complete LED lighting solution to optimize your indoor growing in a 120x120 cm tent. This pack includes two Sanlight EVO 4-120 LED bars, each 190W, for a total power of 380W with an efficiency of 2.9 µmol/J. Developed by Sanlight's Austrian engineers, this kit includes all necessary accessories: separate dimmers, adjustable fixings, and complete cabling for a hassle-free installation.
Why choose the Sanlight EVO 4 Set 120x120 Pack?
Frankly, this pack is a game-changer compared to older 600W HPS systems. With its 380W consumption, it delivers a uniform PPFD of 900-1000 µmol/m²/s across the entire growing area, equivalent to a dual HPS but with 40% less power consumption. The Samsung LM301H and Osram Deep Red 660nm diodes guarantee an optimized full-spectrum (3000K + 660nm) that boosts both vegetative growth and flowering.
The major advantage is thermal management. Where a 600W HPS emits 400W of heat, each EVO 4-120 produces only 60W of thermal energy. In a 120x120 tent, this changes everything for ventilation. No need for an oversized 400 m³/h extractor; a 200-250 m³/h model is more than sufficient. The separate dimmers allow for fine-tuning of intensity according to the phases: 40-50% during growth, 80-100% during flowering.
How to properly install your Sanlight EVO 4 Set Pack
Installation is designed to be intuitive. The adjustable fixings mount directly onto the tent poles, without drilling or DIY. Position the two EVO 4-120s in parallel, spaced approximately 40 cm apart for uniform coverage. The optimal height varies depending on the phase: 60-80 cm during growth, 30-40 cm during flowering with dimmers at full power.
Wiring is simplified thanks to IP65 waterproof connectors. Each bar connects to its dedicated dimmer, then the two dimmers connect to the main power supply. This configuration allows for differentiated lighting zones if needed, practical for managing multiple varieties with distinct needs in the same tent.
Frequently Asked Questions
Is this Sanlight EVO 4 Set 120x120 pack suitable for my 120x120 cm tent?
Absolutely, this pack is specifically designed for 120x120 cm tents. The two EVO 4-120 bars, each 118 cm long, perfectly cover this area with a uniform PPFD of 900-1000 µmol/m²/s. Light distribution is optimized to avoid shaded areas, even in the corners. With 380W spread over 1.44 m², you get a light density of 264W/m², ideal for demanding crops.
How do I adjust the Sanlight pack dimmers for the vegetative and flowering phases?
During the vegetative phase, set the dimmers between 40-60% depending on plant size. For seedlings or cuttings, start at 30% and gradually increase. During flowering, push to 80-100% to maximize production. The dimmers allow for fine adjustment from 0 to 100% in 1% increments. This precision avoids light stress while optimizing photosynthesis according to the needs of each phase.
What ventilation is needed to manage the heat from the two EVO 4-120s in a 120x120 tent?
A 200-250 m³/h extractor is largely sufficient to dissipate the 120W of thermal energy generated by the two bars. This is much less than a 600W HPS which emits 400W of heat. Plan for passive or active intake of 150-200 m³/h for air renewal. With proper ventilation, the temperature remains stable between 24-26°C, even with dimmers at 100%. The absence of hot spots greatly simplifies climate management.
How to easily install the Sanlight pack with its included fixings and cabling?
Installation takes less than 30 minutes thanks to Sanlight's patented fixings. Simply clip the supports onto the tent poles, position the two EVO 4-120s in parallel, then connect each bar to its dimmer via the supplied cables. The IP65 waterproof connectors snap together without tools. Then connect the two dimmers to the main power supply, and you're done. No drilling or soldering required, everything is plug-and-play.
Should the optics of the Sanlight EVO LEDs be cleaned, and how to maintain efficiency?
Monthly cleaning of the optics maintains optimal efficiency. Use a slightly damp microfiber cloth with 70% isopropyl alcohol. Avoid harsh chemicals that could damage the anti-reflective coating. Always unplug the light before cleaning and wait for it to cool completely. Clean optics retain 98% of the luminous flux, while dust can reduce efficiency by 10-15% after a few months of intensive use.
