1000W DE Deep reflector

The fully redesigned DLI HORTI-Series 1000W DE is the new standard in the market. With the unique positioning of the ballast and by using the best materials only, DLI has succeeded in developing a fixture that is unsurpassed the cooling of the electronics. Proper cooling of the electronics increases the lifespan and greatly increases reliability. Independent tests confirm that the DLI HORTI-series is the coolest fixture available on the market today!

Time for Improvement

For Decades growers have settled for grow light fixtures that are not 100% tailored for their use and crop. Grow light manufacturers are always trying to appease the mass populations of growers, rather than honing in on exactly what they need for optimal performance, yields, and most important a high quality product, year round.

Redefining the Light Fixture

With almost a century of experience in developing, manufacturing and selling grow light fixtures to the internationalhorticultural industry, the DLI-team has redefined the HPS fixture in order to be able to continue to meet the high demands set by our customers in the modern horticultural industry.

DLI proudly presents the redefined HORTI-series. DLI is setting a new standard in the horticultural sector with this, in-house developed, HPS fixture. Due to the unique position of the electronic ballast in the die-cast aluminum housing and the use of materials and components of the highest quality, our engineers have succeeded in developing a fixture that is unequalled in the cooling of the electronics. The superb cooling of the electronics results in high reliability and a long service life of the fixture. Independent tests show that the DLI HORTI-series is the coolest fixture on the market!

The low housing makes it possible to install the fixture as high as possible above the crop, which results in an improved light uniformity on the crop. The project-specific made wire brackets make an easy installation of the fixtures on truss or C-profile possible. The brackets are carefully designed to ensure that the fixture is always level, both horizontally and vertically.


Efficiency and uniformity have been the main focus in the development of the reflectors. Each ray of light coming from the lamp either goes directly to the plant or will hit the 99.99% pure aluminum only once before being transmitted to the plant. The unique design of the DLI reflector ensures a uniform light distribution and therefor an even plant growth. There is a choice of a deep reflector or a reflector with a wide light distribution.

The reflectors from DLI are made from an electrochemically brightened high purity aluminum substrate coil, with an anodized base coat for a maximum protection of the surface. The material is then treated with specially developed processes to ensure maximum adhesion of the coating. A reflection layer of 99.99% pure aluminum is applied by means ofvacuum coating. A double layer oxide system is applied to this reflection layer. This improves the total reflection and offers protection against damage.
