R&D geared toward high-power LED grow lights

Makers are leveraging LED advancements to expand 30 to 1,200W selections.

LED grow light suppliers in China are rolling out models with better price-performance ratios. In doing so, they hope to make the luminaires more attractive alternatives to halogen, fluorescent and HID versions.

Diode-fitted designs already account for about 60 percent of output in the indoor gardening lamps category. The line's share is expected to expand further in coming years as the technology matures and costs decline.

Under efforts of boosting the viability of LED luminaires, many companies are expanding high-power selections. The focus is on the 30 to 1,200W range, which covers the best-selling sizes in other grow lights.

Suitable for large gardens, models can yield more lumens per watt compared with traditional counterparts. In general LED-fitted versions use 50 percent less energy.

Other makers are highlighting that diode-based designs have better lumen maintenance than older technologies. The output of fluorescent and sodium lamps, for example, show a decrease after only three months.

In line with this endeavor, the circuitry of LED designs is being adjusted to improve the dissipation of heat, which is the primary source of lumen depreciation. Such upgrades also aim to ensure that all bulbs in the fixture work efficiently.

Cost control is a major consideration in product development as well, since diode-fitted selections are significantly more expensive than alternatives. This stems mainly from the fact that core technologies belong to a few companies, most of which are foreign-invested.

More than 90 percent of mainland China's grow light exports adopt LED chips procured in Taiwan or farther overseas. Epistar, Cree, Osram and Nichia are the common sources of the components. Versions from these suppliers are at least twice as expensive as domestic counterparts.

Keeping expenses down has become more challenging in past months, with the cost of various manufacturing inputs on the upswing. Chips, for instance, became 30 to 50 percent more expensive between August and December of last year.

A major housing option, aluminum was at $1.14 per pound in February. This rate is 25 percent higher than levels six months previously.

To minimize the effect of manufacturing outlay on prices, suppliers are looking to adopt less expensive components for their low-end and midrange selections. They will continue to utilize overseas-made chips for upscale releases.

The selection comprises models rated up to 1,200W. Most emit blue and red light in the 430 to 470 and 620 to 660nm bands, respectively.

Designs are available starting at $20 per set. Generally, the higher the power, the more expensive the lamp. Fixtures rated less than 5W, for example, do not exceed $50. Versions consuming between 90 and 300W reach $250.

Models adopt bulbs that are rated 1 to 3W. For the housing and other parts, cast iron, aluminum and stainless steel top raw material options.

Surfaces are usually electroplated with zinc or chrome, although nickel is offered for high-end variants. Midlevel and upscale designs may be treated for water resistance.

LED grow lights are designed to be installed at 2 to 5m heights. Coverage varies depending mainly on the power of the unit.

Models can be sourced from about 500 companies in China. Approximately 95 percent of the supplier base consists of private enterprises, most of which are located in Guangdong province.
