Impact of Nighttime LED Streetlights on Crop Growth
Crop Growth Cycle => Nutrient Production during the Day => Growth with Nutrients at Night
Day => Receives Sunlight => Photosynthesis Process => Nutrient Production => Nutrient Storage in Stems, etc.
Night => 3 Hours after Sunset => Distribution of Stored Nutrients => Plant Growth, Fruits, Roots, etc.
Crops perceive nighttime LED streetlight as daylight, disrupting nighttime plant growth activities, leading to damage.

Preventing Crop Damage Solar LED Streetlights
“LED Lighting for Crop Growth Protection from Artificial Lighting”
MTC LED streetlights eliminate the 380 to 500nm wavelength blue light, which promotes photosynthesis, using semiconductor technology. They activate the 500 to 640nm wavelength green light, which does not assist in photosynthesis. This allows crops to carry out nutrient distribution activities properly even under streetlight, promoting normal growth.
With MTC LED streetlights installed, it's possible to brightly illuminate fields around agricultural areas and roads at night without affecting crops. There's no need to turn off LED streetlights at night or use light-blocking curtains.

Comparison and Analysis of Wavelengths between Conventional Lighting and MTC
Pest protection effect
MTC LED products use semiconductor technology to adjust the wavelength of light to prevent pest damage and crop damage. In addition, it can save 75% of electricity costs.
Actual test results
General insect-proof LED products
General LED products (including street lamps) are sold on the market without removing the blue light wavelength due to insufficient technology, which is causing pest damage.
MTC insect-proof LED products
MTC insect-proof LED products (including street lamps) contain innovative technology that blocks blue light, preventing pest damage.

1. Blue Light Blocking LED Products
Producing 'Anti-Bug LED Lighting Products' that protect human living spaces and health from insect damage, using third-generation smart LED lighting technology to adjust wavelength, color temperature, brightness, etc., widely spreading worldwide.
2. Up to 75% Savings in Power Costs
MTC's luminous efficiency is about twice as high as that of other companies, and power consumption is about half as much as that of other companies.
| Category | MTC | K Company | D Company | P Company | G Company |
|---|---|---|---|---|---|
| Energy Consumption Efficiency Grade | Grade 1 | Grade 4 | Grade 4 | Grade 5 | Grade 4 |
| Luminous Efficiency (lm/W) | 105 | 75 | 50 | 14 | 57 |
| Power Consumption | 5W | 9W | 12W | 8W | 7W |
3. Carbon Reduction LED Streetlights Using Environmentally Friendly Materials
While conventional streetlight housings are made of 100% plastic, MTC applies graphene patented technology to produce housings (covers) using a mixture of coffee grounds and oyster shells (recyclable), contributing to carbon reduction.
4. Carbon Reduction LED Streetlights with No Electricity Usage
MTC's Anti-Bug LED Streetlights are made using solar power, contributing to carbon reduction by eliminating the use of energy (electricity).
