About The Spectrum King Brand
Spectrum King aims to provide value to customers by making the most efficient LED grow lights without losing quality or reliability. They are designed using IP65 ratings and are recognized by the international standard designating products fit for use in humid and wet conditions. Few companies qualify for this certification. The IP65 compliance also means you can spray in your canopies without damaging the light’s internal components. Spectrum King is a better-known brand for commercial-level grow companies. However, the product quality makes them a good choice for anyone wanting to improve their cloning process.

Recommended Add Ons
You can purchase a Spectrum King LED SK600 with or without a reflector. If it doesn’t have a reflector, you can purchase the 120 or 90 Degree Reflector Kit for SK600. Reflectors help get light to your plants efficiently and spread the light evenly over the plants. You can also choose to purchase a manual dimmer add-on. This product lets you turn the power down to as low as 10 percent when you want to reduce the light intensity. Generally, using a dimmer will not impact the full spectrum output.

How The Spectrum King LED SK602 Helps Your Plant
The Spectrum King SK602 LED grow light emits a full spectrum of light, meaning it mimics natural sunlight. This white light allows your plants to undergo natural photorespiration. While plants need red and blue light wavelengths for photosynthesis, oversaturating them with these two lights can lead to underproduced plants. A full spectrum of light allows them to intake nutrients efficiently, leading to:
- Healthier growth
- Sturdier plants
- Increased yields
How to Hang Your Spectrum King LED SK602 Grow Light
A standard rope ratchet will easily hold Spectrum King LED grow lights. However, the carabiner may be too small to fit the lights, so Spectrum King recommends using the attached “S” hook to hang the light easily. You can use the center ring to hang the light or use the additional bracket to hang the grow light at any angle. The position of your grow light will also determine the coverage area of the light. The higher you raise your light, the greater coverage area you get. However, it also decreases the light intensity. You want to ensure you find the right balance of intensity and coverage for your plants. Depending on the type of plant, the following coverage is recommended:
- Flowering plants: between 16 to 25 square feet, or 4×4 to 5×5 feet.
- Vegetative plants: between 36 to 64 square feet, or 6×6 to 8×8 feet.
Different placement heights will accomplish the recommended coverage. For vegetative plants, hang it between 36 to 48 inches from your plants. For flowering plants, hang it at least 28 inches from your plants. Also, note that the type of reflector on your light (90 degrees or 120 degrees) will impact the height required for coverage. A 120 degrees reflector will have greater coverage at lower heights compared to a 90 degrees reflector.
This Spectrum King LED review aims to help you feel confident when purchasing your Spectrum King SK602 LED grow light. While the price can be hefty, it is an efficient product that allows you to save money in the long term and contains many features optimal for growing healthy plants.
