Ceres e5

Ceres e5 is a primary or secondary growth light system developed as a HPS or HID replacement.

Ceres-e5 is a primary or secondary medium to high bay growth light system specifically developed as a HPS or HID replacement for greenhouses and indoor growing facilities.

Ceres e5 is our brightest and most efficient fixture yet!

Pushing 3.1 µmol/W – a single Ceres-e5 consumes only 515W while generating absorbable photon flux equivalent to 1300W HPS. Your electric bill and your plants with thank you.

Control your grow

As with almost all our fixtures, Ceres e5 has optional wavelength control. With up to 7 individually controllable wavelength channels, this fixture will have you prepared for any crops, conditions, strains, or growth characteristics you want to achieve. Fixture can be equipped with manual controls or wireless controls. Crop-specific non-controllable options are also available.

Designed with harsh, humid environments in mind

Ceres e5 is completely sealed and has no moving parts. Fixtures can run for over 70,000 hours with no light degradation.

I am the scientist at a large greenhouse, We are one of the biggest herb grower in Ontario. We are using artificial lights around the year to shorten the grow cycle.

Yunustech showed us their new CERES light. Yunustech’s lights do not have mechanical fans which is a big advantage for green houses. As happens in many greenhouses, occasionally we need to use pulverized substances which accumulate on the propellers and cause premature failures. Another very nice feature is that Yunustech’s lights are dynamic. The wavelength combination are controlled from control room wirelessly. We are in the process of developing our own lighting programs. The positive effect of the wavelength control became evident within the very first week. I am looking forward for Yunustech’s new series of green house lights.
