Shenzhen Liweida Optoelectronics Co., Ltd.

1. Specification

 2. Product Introduction

This led grow light has low power consumption,high luminous efficiency and long service life. These growing lamps emit the wavelength of light which can be fully absorbed by the plants photosynthesis; no energy waste like fluorescent lights etc. 630 and 460nm are respectively 2 peaks of growth spectrum for maximum chlorophyII A and B production. Sources rich in red light are more efficient and beneficial for photosynthesis, best for blooming and fruit .The Chlorophyll and Carotenoid need blue much, good for the photosynthesis, best for promoting the leaf.This lamp is waterproof ,IP65.

Advantages of LED plant lights:

   1. No need for a standard power outlet connector for the drive or cooling fan.
   2. The environment where red and blue wavelengths are required for plant growth.

   3. Compared with other general lighting equipment, LED plant light lines are mild

   and will not burn the seedling plants.
   4. Save 10% ~ 20% of electricity costs compared to other plant lighting.
   5 blue light can promote plant growth, red light makes plants bloom

3. Product Features

1. LED PAR20(7W), PAR30(12W) and PAR38(15W) are available.

2. Aluminum housing with good heat dissipation.

3. SMD3020 LED with more brightness and low light decay.

4. Energy-saving lamp can save 80% power.

5. Protection rate is IP65 with waterproof function.

Do plants need high Lumen/Lux?

Lumen/Lux is only for human eyes perceiving, not for plants growth.

So if someone tell you to choose high Lumen/Lux grow lights, please tell them "It"s cool", then walk away.

What"s plants really need is enough PPFD.

What"s the PPFD?
PPFD (Photosynthetic Photon Flux Density) is a measure of the number of photons in the 400-700nm range of the visible light spectrum

(Photosynthetic Active Radiation or PAR) that fall on a square meter of target area per second.

LCP(Light Compensation Point)
LCP is the lowest photosynthesis demands of PPFD. Plants start to grow only when PPFD exceeds LCP.

LSP(Light Saturation Point)
When PPFD reaches a certain intensity, the photosynthetic rate will no longer be increased. That called LSP of PPFD.
