The Sanlight EVO 4-120 1.5 is a precision LED panel built for growers who refuse to compromise on light quality. It suits anyone running a low-height grow cabinet or a tightly managed indoor space where intensity and spectral accuracy matter.

Sanlight is based in Austria and has earned a strong reputation across German-speaking Europe through consistent engineering rather than marketing. Their in-house lighting and electronics laboratory allows them to refine LED chip performance and spectral output in ways that few manufacturers can match. The EVO 4-120 1.5 represents that approach - a panel tuned for real horticultural results, not just impressive box specifications.

The 90° lens design is one of the most practical features for cabinet growers. It concentrates and distributes light across the canopy without needing the large hanging distance that many bare-chip LEDs require. You can position this panel close to the plant tops and still achieve an even spread - a significant advantage when working within the fixed height of a grow box. Combined with a full-spectrum output that supports both photosynthetic efficiency and plant hormone balance, it produces healthier, more productive growth across the whole cycle.

The EVO 1.5 generation pushes chip efficiency beyond 3 µmol/J. In practical terms, that means more usable light reaching your plants for every unit of electricity consumed. Running costs matter over a full growing season, and this level of efficiency is where premium LED genuinely pays back the initial outlay. The optional plug-in dimmer - sold separately at reasonable cost - lets you dial back output during propagation or the early vegetative phase, and also enables a soft sunrise simulation to reduce plant stress when the lights come on.

If you are running a G-Tools G-Kit 1200 Wing, Sanlight recommend using three EVO 4-120 1.5 units to cover the growing surface correctly - check which daisy-chain cables you need when ordering. For longevity, the modular LED design is a genuine advantage: when output eventually degrades after years of use, you replace the LED modules rather than the entire fixture. That makes the EVO 4-120 1.5 a long-term investment rather than a consumable.

Grower’s Note: During early propagation and the first week of vegetative growth, dial the dimmer back to around 40-50% output. Young roots and tender shoots respond better to gradually increasing light levels. Use the sunrise simulation feature to ease plants into the photoperiod - abrupt full-intensity switching can cause minor stress responses that slow early establishment. Step intensity up by around 20% each week until you reach full power at the canopy distances Sanlight specify for this panel.
