Sanlight EVO 4-100 1.5 LED Grow Light

The Sanlight EVO 4-100 1.5 is a high-efficiency full-spectrum LED panel engineered for serious indoor growers who want long-term reliability. It suits growers working in grow cabinets or low-ceiling spaces where light spread at close range is critical.

Sanlight has built a strong reputation in German-speaking Europe by focusing on horticultural science rather than marketing. Their in-house lighting and electronics laboratory informs every design decision. The EVO 4-100 1.5 reflects that approach: the LED chips exceed 3 µmol/J efficiency, meaning you get more usable light for every watt consumed. That matters directly to your electricity bill and your yield.

The 90° lens is a practical feature that sets this panel apart from bare-chip designs. It controls light spread precisely, allowing you to hang the fixture closer to the canopy without hotspots or edge fall-off. In a grow cabinet with limited headroom, that closer hang distance is genuinely useful - you lose far less vertical growing space to the light itself.

What makes the EVO 4-100 1.5 a genuinely long-term purchase is the replaceable LED module system. After years of use, when lumen output drops, you replace only the modules rather than the whole fixture. Replacement modules are available, and future module generations remain compatible. This reduces waste and protects your initial investment over multiple growing seasons.

Pairing this light with the optional Sanlight plug-in dimmer adds real operational flexibility. During propagation and early vegetative growth, running the panel at reduced output cuts heat and eases young plants in gently. The sunrise simulation function increases output gradually when the light period begins, which reduces stress on plants at the light-on transition. We stock compatible Sanlight dimmer accessories alongside this panel.

Grower’s Note: During early vegetative growth, consider running the EVO 4-100 1.5 at 50-70% output via the dimmer. Young cuttings and seedlings respond better to lower light intensity, and gradually increasing output over the first two weeks helps establish stronger root systems before the plant is pushed harder in late veg and flower.
