Sanlight EVO 5-120 LED Grow Light (Gen 1.5)

The Sanlight EVO 5-120 Gen 1.5 is a premium 120cm LED grow light engineered for growers who refuse to compromise on light quality or longevity. It suits serious hobbyists and commercial operators alike, particularly those working inside grow cabinets where ceiling height is limited.

Sanlight has built a strong reputation across German-speaking Europe by producing LED lights that justify their price through measurable performance. The EVO 5-120 Gen 1.5 is a clear example of that approach. The updated Gen 1.5 LED chips push efficiency beyond 3 µmol/J, meaning more usable photons delivered per watt consumed. That translates directly into better yields without a proportional rise in your electricity bill.

The 90° lens array is central to how this fixture performs in confined spaces. Rather than flooding light in a wide, diffuse arc, it directs output downward with controlled spread. You can position it closer to the canopy than a typical LED bar or blurple panel. This matters enormously inside a grow box where you may have just 30-40cm of headroom between the light and your tallest plant tops.

A standout feature for long-term value is the replaceable LED module system. Most LED fixtures become obsolete when output degrades - the EVO 5-120 does not. When the chips eventually dim after years of use, you replace the modules rather than the entire unit. Paired with Sanlight's optional plug-in dimmer, you also gain the ability to dial back output during propagation and seedling stages, protecting young plants from excessive intensity. The sunrise simulation function ramps output gradually at switch-on, which reduces stress on both plants and driver electronics.

This light pairs naturally with the G-Tools grow cabinets we stock. The 120cm length aligns well with cabinet widths in the 1.0-1.2m range. For climate management alongside this panel, consider a quality inline fan and carbon filter to handle the heat and odour that a productive canopy generates. The EVO 5-120 is not a budget entry point - but for growers investing in a setup they intend to run for five years or more, the cost per harvest across its lifespan is genuinely competitive.

Grower’s Note: During the first two weeks of vegetative growth, use the dimmer to run the EVO 5-120 at 50-60% output. Young root systems cannot yet support the transpiration demand that maximum intensity creates. Ramp up gradually over 10-14 days. This practice also helps you identify heat or humidity imbalances in your cabinet before they affect established plants.
