Sanlight EVO 3-100 1.5 LED Grow Light

The Sanlight EVO 3-100 1.5 is a premium Austrian LED grow light built for growers who refuse to compromise on light quality. Its compact, low-profile form and 90° lensed output make it particularly well suited to grow cabinets where vertical space is tight.

Sanlight has built a strong reputation in the German-speaking horticultural market by investing heavily in its own in-house lighting and electronics laboratory. The EVO series is the result of that long-term research: LED chips rated at 2.7 µmol/J place this fixture firmly at the efficient end of the market. For UK growers used to high running costs, that efficiency translates directly into lower electricity bills and less heat to manage.

The 90° lens angle is a deliberate design choice. Rather than relying on bare-chip diffusion, the optics deliver a controlled, even spread across the growing surface. This matters most in compact grow boxes, where a light hung close to the canopy could otherwise create hot-spots. With the EVO 3-100 1.5 you can position it low without scorching the tops of your plants, which is a genuine advantage in any cabinet with limited headroom.

One of the most practical features of the EVO series is its long-term serviceability. When LED output eventually declines after years of use, the modules themselves can be replaced independently. You are not forced to buy an entirely new fixture. Pair the EVO 3-100 1.5 with the optional Sanlight plug-in dimmer to manage intensity during propagation and early vegetative growth, and to programme a gradual sunrise ramp that avoids the abrupt light shock of an instant full-power switch-on.

This light sits naturally alongside G-Tools grow cabinets in our range. The controlled beam angle and low-profile dimensions make it one of the more considered choices for a sealed or semi-sealed cabinet environment. For climate control, pair it with an appropriately sized inline fan and carbon filter to keep temperature and odour in check. Because the EVO 3-100 1.5 runs efficiently, thermal load is lower than equivalent HPS or less-efficient LED fixtures, giving your climate equipment an easier job.

Grower’s Note: During propagation and the first week of vegetative growth, dial the dimmer back to around 40-50% output. Young roots cannot yet support the transpiration demand that full-power LED intensity creates, and lower light levels during establishment encourage downward root development rather than stretching. Ramp intensity gradually over two to three weeks as the plant's root zone develops.
