HPS (High-pressure sodium lamps) were once the mainstream light source in the field of plant lighting. However, with the rapid development of LED technology, its disadvantages have gradually become more prominent, and it is currently in a stage of accelerated elimination.
Why not continue using HPS?
Do you know that the European Union has been gradually phasing out the use of HPS lights as part of its broader environmental and energy efficiency goals?
Due to high energy consumption, spectral mismatch, high maintenance costs, and environmental protection issues, HPS is being comprehensively replaced by LEDs. The photoelectric conversion efficiency of HPS is only about 1.3 μmol/J, while that of LEDs can reach more than 2.6 μmol/J. Under the same light output, the energy consumption of HPS is more than twice that of LEDs, which is very inefficient. At the same time, a large amount of heat is generated during the operation of HPS (the bulb temperature can reach above 400°C), and an additional heat dissipation system needs to be configured, resulting in a further increase in overall energy consumption. Energy consumption costs account for 50%-60% of the operating cost. Taking a 600W HPS lamp as an example, the annual electricity cost is about 2-3 times that of an LED lamp with the same light efficiency, and the long-term use cost is significantly higher than that of LEDs. In response to the various disadvantages of HPS.
Meet HLEDTLR: A 1:1 replcer of HPS
Westland has brought the exclusive patented products HLEDTLR 600W&1000W.
The design concept of HLEDTLR is to enable 1:1 replacement of HPS for its customers and to customize the spectrum specifically for the needs of different crops. Customers can optionally retain their original HPS ballasts and install and use them directly. The design of type A heat dissipation holes + multi-layer aluminum sheets increases the heat conduction efficiency by 40%, ensuring the long-term stable operation of the lamp. The whole lamp can be directly washed and cleaned with water, without fear of a humid and dusty environment. The double-row module design makes the price of the 1000W lamp equivalent to half of that of an ordinary 600W top lamp (about $173, depends on spectrum and LED chips)! After installation, there is no need to frequently replace the light source like with HPS, saving labor costs!
Spectrum of HLEDTLR
There are four spectra available for HLEDTLR planting (customization is possible), and it has very good planting performance in both solar greenhouses and indoor planting! Most crops planted in greenhouses and indoors can be planted using HLEDTLR (by adjusting the spectrum). Taking hemp as an example, the R48 spectrum is rich in red light, creating the best conditions for the vigorous growth of hemp and effectively increasing the yield of cannabinoids.
