SANSI Puck LED Grow Lights 10W 2-Head Full Spectrum (4000K) — Compact, Energy-Efficient Indoor Plant Lighting

These two-headed LED grow lights deliver a daylight-balanced full spectrum that covers the visible range from 400–780nm, supporting plants through every growth stage. Using SANSI's patented chip-on-ceramic thermal design, the lights run cooler and more reliably than many traditional LED modules while remaining energy-efficient at just 10 watts (about a 150W incandescent equivalent). The puck form factor and included mounting accessories make it simple to position the lights above seedlings, foliage plants, or micro-greens without taking up shelf space.

How does this light support different plant growth stages?

The SANSI Puck emits a broad spectrum close to natural daylight (4000K) with a high color rendering index near Ra 100, so color and intensity mimic sunlight across seedling, vegetative, and flowering phases. That range helps leaves photosynthesize efficiently while allowing you to visually inspect colors and health.

• Full visible spectrum (400–780nm) for balanced growth
• 4000K daylight color for accurate plant color rendering
• Suitable as a supplemental light for seedlings, greens, and ornamental plants

What makes SANSI’s ceramic technology better than standard LED designs?

SANSI uses a patented chip-on-ceramic method that solders the LED chip directly to a ceramic heat sink instead of aluminum-based MCPCB. This lowers thermal resistance from the LED junction to the sink so heat moves away faster, improving efficiency and product longevity.

• Direct chip soldering to ceramic reduces system thermal resistance
• Faster heat dissipation yields steadier light output over time
• Improved reliability compared with conventional aluminum-substrate LEDs

How do I install and position the 2-head puck lights in my indoor setup?

The puck’s lightweight, low-profile design is built for flexible mounting: stick them to shelves, cabinets, greenhouse frames, or tuck them under a ledge. A 71-inch power cord plus included double-sided tape and zip ties give multiple mounting options without extra parts.

• Compact two-headed puck fits tight spaces and multi-tier shelves
• 71" power cord reaches most indoor placements without extension
• Includes tape and zip ties for quick, tool-free installation

How energy efficient and cost-effective are these grow lights?

Rated at 10 watts, each SANSI puck replaces roughly a 150W incandescent equivalent in light output while using a fraction of the electricity. For heavy daily use (for example 18 hours per day), annual energy cost estimates remain low, making these lights a budget-friendly option for continuous supplemental lighting.

• 10W actual power draw with high light efficiency
• Estimated low annual running cost under typical indoor schedules
• Compact design reduces need for multiple bulky fixtures

Who is this for? The SANSI Puck Grow Lights are designed for hobby gardeners, apartment plant parents, micro-green growers, and anyone needing targeted supplemental lighting in limited spaces. They suit users who want a daylight-accurate spectrum, a low-heat fixture, and a simple installation method—especially where space or budget limits rule out larger grow arrays.
