Features and Construction

This grow light bulb is designed with practical features that make it suitable for both hobbyists and more serious indoor growers. The combination of power options, protective shell, and simple installation gives you flexibility without complexity.

Power Options and Plant Types

The bulb is offered in four power levels: 9W, 12W, 15W, and 18W. Dedicated versions are available for chrysanthemum planting, succulent planting, dragon fruit planting, and passion fruit planting, allowing you to select the intensity that best matches each plant's light requirements. Higher wattages generally produce more light output, useful for larger or more light-demanding plants.

Material and Build

The outer shell is made from PC (polycarbonate), a lightweight plastic that resists impacts and handling. The IP54 protection rating means the bulb is protected against limited dust ingress and splashing water from any direction, making it suitable for use in humid environments like greenhouses or covered patios. The bulb runs on a standard 220V input voltage.

Size and Practical Fit

Exact dimensions are not specified, but the bulb is designed to fit into common E27 lamp holders. Its compact form factor means it can be used in existing light fixtures, clamp lamps, or dedicated grow light reflectors without taking up excessive space.

Uses and Placement

This fill light bulb is best used as a supplemental light source to extend daylight hours or to compensate for low natural light conditions. Proper placement is key to getting good results.

Indoor Plant Lighting

Position the bulb 20-40 cm above your plants to provide an additional light source. This is especially useful for seedlings, cuttings, or plants in rooms with north-facing windows or limited sunlight. The dedicated versions for chrysanthemum, succulent, dragon fruit, and passion fruit indicate the bulb's spectrum is tailored to support these plants' growth.

Greenhouse and Covered Areas

Thanks to its IP54 rating, the bulb can be used in covered greenhouse environments where humidity and occasional splashes occur. It can supplement natural light during overcast days or winter months to help maintain plant health and growth rates.

Benefits and Buying Value
