The KS5000 is an LED grow light designed for horticultural applications, featuring Samsung LM301H diodes and Osram 660NM diodes. It is suitable for all stages of plant growth and flowering, offering a dimmable light output.
Function Description:
The KS5000 serves as a high-efficiency lighting solution for indoor plant cultivation, providing a full spectrum of light necessary for photosynthesis. It is designed to replace 1000W HPS/MH lighting systems, offering significant energy savings and a longer lifespan. The dimmable feature allows users to adjust the light intensity according to the specific growth stage of their plants, from seedlings to flowering. The light can be used as a standalone unit or integrated into a larger lighting system with multiple fixtures, controlled by a third-party 10V PWM controller.

PPFD Maps and Usage Suggestions:
The manual provides detailed PPFD (Photosynthetic Photon Flux Density) maps for a 4.0 x 4.0 ft grow tent, illustrating light intensity at different hanging heights and dimming levels for various growth stages:
- Seedling Stage (50% Brightness): Distance 30" (77cm), Power Draw 250 Watts, Maximum PPFD 403 µmol/m²/s, Average PPFD 367 µmol/m²/s, Using Hours 18 on / 6 off.
- Vegetative Stage (75% Brightness): Distance 28" (70cm), Power Draw 375 Watts, Maximum PPFD 602 µmol/m²/s, Average PPFD 540 µmol/m²/s, Using Hours 18 on / 6 off.
- Flowering Stage (100% Brightness): Distance 16" (40cm), Power Draw 500 Watts, Maximum PPFD 1000 µmol/m²/s, Average PPFD 833 µmol/m²/s, Using Hours 12 on / 12 off.
Planting Suggestions (µmol/m²/s):
The manual offers recommended light intensities for different plant species and growth stages:
- Canna Plants: Seed 200-400, Vegetative Cutting 75-150, Vegetative 400-600, Flower/Fruit/Reproductive 600-1000 (No CO2)
- Tomatoes: Seed 150-350, Vegetative Cutting 75-150, Vegetative 350-600, Flower/Fruit/Reproductive 600+
- Cucumbers: Seed 100-300, Vegetative 300-600, Flower/Fruit/Reproductive 600+
- Peppers: Seed 150-350, Vegetative 300-600, Flower/Fruit/Reproductive 600+
Usage Features:
- Installation: The light fixture should be unfolded and placed with LEDs facing downward. Rope ratchets are attached to hanging holes and then raised to the desired hanging height in a safety mounting location. The LED driver can be placed inside or outside the grow tent.
- Connection: The driver power cord connects to the light, twisting to lock. Brightness is adjusted based on desired light intensity.
- Multiple Fixtures: Multiple KS5000 fixtures can be connected in a chain. The output of the first driver connects to the input of the next, and so on. All drivers except the first should be set to "EXT" (external control). The entire chain is then controlled by the first driver. Unlimited fixtures can be connected, though the controller determines the maximum number.
- Controller Integration: The KS5000 is compatible with most third-party 10V PWM controllers. The controller's output connects to the input of the first driver in the lighting system chain. The order of network cables for output on the controller must match the input on the driver.
- Light Intensity Management: It is recommended to slowly increase light intensity as plants develop to prevent photo-oxidation (photo-bleaching) of chlorophyll pigments. Specific recommendations are provided for seedlings (hang light high, break-in period), clones (gentle light, rootless stage), vegetative (high white light for lush growth), flowering (large amounts of light needed), and late flower (maturation/ripening).
Maintenance Features:
- Cleaning: Before cleaning, the light must be shut off and unplugged. Use a clean, soft, lint-free cloth to wipe the light, avoiding moisture in any openings.
- Environmental Control: The maximum ambient temperature for safe operation is 104°F (40°C). Mechanical ventilation or a cooling system is required to maintain this temperature in the growing space.
- Cord Management: Cords should not be concealed, extended through building structures, located above suspended ceilings, or permanently affixed. They must be routed to prevent strain and physical damage, be visible along their entire length, and used within their rated ampacity.
- Indoor Use Only: The equipment is for indoor use only and is not waterproof. It must be protected from dampness, dust, and water.
- Air Circulation: The light should be set up in an environment that allows for adequate air circulation. Ventilation openings should never be obstructed.
- Safety Precautions: Do not look directly at the LED bulbs when the light is working, as it emits possibly hazardous optical radiation that may be harmful to the eyes. The light housing's temperature will increase after several hours of operation; avoid touching the operating lamp. Installation of horticultural lighting structures must be performed by qualified personnel and approved by the authority having jurisdiction.
- Coverage: 3-year warranty against manufacturing defects from the date of purchase for products purchased in the United States.
- Exclusions: Damage due to high moisture levels, water, power surges, improper hanging or mounting, incorrect use, dust build-up, or user modifications are not covered.
- Returns (within 30 days): For quality issues within 30 days, customers receive a prepaid return label and can choose between a free replacement, a full money-back refund, or free repair (parts sent immediately or light returned for fixing).
- Returns (after 30 days): For quality issues after 30 days, customers can receive free parts immediately for missing parts or accessories, or return the light for free repair with a provided prepaid shipping label.
- International Customers: Customers outside the US also receive a 3-year US warranty, but shipping costs to and from the US warranty center are the buyer's responsibility. Repairs are only processed within the United States.
- Out-of-Warranty Service: Warranty service may still be performed for lights not covered under warranty, at the company's discretion, and may incur a cost.
- The company reserves the right of interpretation for its warranty structure.
