HLG Reflector Series: LED Grow Lights with Integrated Reflectors for Indoor Cultivation

Horticulture Lighting Group's Reflector Series revolutionizes grow lighting with its high-performance LEDs equipped with integrated reflectors. These lamps combine the energy efficiency of Samsung diodes with optimized light distribution thanks to their specially designed reflectors. Each model in this series offers uniform coverage and exceptional light penetration to maximize your yields.

Why choose Reflector Series LED lamps

The integrated reflectors of the Reflector Series are a complete game-changer compared to classic LEDs. Where a standard LED scatters light in all directions, these models concentrate and direct every photon towards your plants. The result? Photosynthetic efficiency that can exceed 2.7 µmol/J depending on the model, which is 30% better than a traditional 600W HPS.

Dual-zone dimming is the other major asset of this series. You can independently adjust the intensity of the center and periphery of your grow area. Frankly, this puts an end to dark spots in the corners and light stress in the center. This technology allows for precise lighting adaptation according to the development stage: 200-400 µmol/m²/s during growth, up to 800-1000 µmol/m²/s during flowering.

The robust construction with extruded aluminum heat sinks guarantees a lifespan of over 50,000 hours. Integrated Meanwell drivers support voltage variations and offer surge protection. In terms of spectrum, the combination of 3000K and 5000K white diodes with 660nm red faithfully reproduces sunlight.

How to choose your Reflector Series lamp

The grow area primarily determines the model to select. For an 80x80cm grow tent, a 320W lamp from the series is more than sufficient. 120x120cm spaces typically require 480W, while large installations of 150x150cm and more benefit from 650W models or more powerful ones like the Scorpion Ultima X Diablo.

Ceiling height also influences your choice. These lamps with integrated reflectors require suspension between 30 and 60cm depending on the power. In a low 160cm grow tent, prioritize compact models. For spaces of 2m and more, you can opt for high-power versions without thermal management issues.

The type of cultivation also matters. For SOG with many small plants, the uniform distribution of the reflectors excels. In SCROG or with large plants, dual-zone dimming allows for intensity adaptation according to foliage density zones. Hydroponic growers particularly appreciate the precise control of DLI (Daily Light Integral).

Frequently Asked Questions

What grow area does the HLG Scorpion Ultima X Diablo from the Reflector Series cover?

The HLG Scorpion Ultima X Diablo effectively covers a 150x150cm area during flowering with an intensity of 800-1000 µmol/m²/s. During vegetative growth, it can illuminate up to 180x180cm with 400-600 µmol/m²/s. This 650W lamp develops a uniform PPFD thanks to its integrated reflectors that eliminate hot spots. The optimized spectral distribution with 2700K, 3000K, 5000K, and 660nm red guarantees maximum photosynthesis across the entire canopy.

How to use the dual-zone dimming of Reflector Series lamps to avoid light stress?

Dual-zone dimming allows for separate adjustment of the center (zone A) and periphery (zone B) intensity via two dedicated potentiometers. Start by setting the central zone to 60% and the periphery to 80% to avoid stress in the center while maintaining sufficient intensity at the edges. Gradually increase by 10% per week according to plant reaction. This gradual approach prevents leaf bleaching and optimizes photosynthesis across the entire surface. Young plants tolerate 200-300 µmol/m²/s uniformly distributed better.

What is the recommended hanging height for the integrated reflectors of the Reflector Series?

The optimal height varies depending on the power: 45-60cm for 320-480W models, 50-70cm for 650W and higher versions. Integrated reflectors concentrate light, requiring more distance than LEDs without reflectors. Start at 60cm during growth and adjust according to PPFD measurements with a quantum meter. The goal: 400-600 µmol/m²/s in vegetative, 800-1000 µmol/m²/s in flowering. Too low a suspension causes thermal and light stress, too high reduces photosynthetic efficiency.

Is a specific timer needed to independently control the cycles of Reflector Series lamps?

A standard 16A timer is sufficient for most Reflector Series models, but a dimmable controller offers a significant advantage. 0-10V compatible models allow for programming variable intensity cycles: progressive sunrise and sunset, reduced intensity at the beginning of the cycle, light peaks in the middle of the photoperiod. This biomimetic approach improves plant health and optimizes electricity consumption. For dual-zone dimming, two separate controllers offer maximum flexibility according to the specific needs of each grow zone.

How to maintain the reflectors of HLG Reflector Series lamps to maintain light efficiency?

Clean the reflectors every 2-3 months with a slightly damp microfiber cloth and 70% isopropyl alcohol. Avoid abrasive products that would scratch the reflective surface. Always unplug the lamp and wait for it to cool completely before cleaning. A dirty reflector can lose up to 15% light efficiency in 6 months of intensive use. Also check the condition of the seals and connectors during each cleaning. Dust and humidity are the main enemies of the longevity of integrated reflectors.
