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.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this light support different plant growth stages?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFull visible spectrum (400–780nm) for balanced growth\u003c\/li\u003e\n  \u003cli\u003e4000K daylight color for accurate plant color rendering\u003c\/li\u003e\n  \u003cli\u003eSuitable as a supplemental light for seedlings, greens, and ornamental plants\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes SANSI’s ceramic technology better than standard LED designs?\u003c\/h3\u003e\n\u003cp\u003eSANSI 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect chip soldering to ceramic reduces system thermal resistance\u003c\/li\u003e\n  \u003cli\u003eFaster heat dissipation yields steadier light output over time\u003c\/li\u003e\n  \u003cli\u003eImproved reliability compared with conventional aluminum-substrate LEDs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install and position the 2-head puck lights in my indoor setup?\u003c\/h3\u003e\n\u003cp\u003eThe puck’s lightweight, low-profile design is built for flexible mounting: stick them to shelves, cabinets, greenhouse frames, or tuck them under a ledge.

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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e10W actual power draw with high light efficiency\u003c\/li\u003e\n  \u003cli\u003eEstimated low annual running cost under typical indoor schedules\u003c\/li\u003e\n  \u003cli\u003eCompact design reduces need for multiple bulky fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho 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.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the SANSI Puck for seedlings and mature plants?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
