This advanced formulation supports plants through vegetative and flowering stages, enhancing overall growth, yield, and quality. Its high PPF and PPFD values ensure efficient light delivery, crucial for indoor gardening success in India's varied climates. The ETL listing provides verified quality and safety, offering peace of mind for dedicated plant enthusiasts. **Ideal for Indian Homes vs. Local Alternatives** — This bulb is perfect for urban apartments and homes in India needing supplemental light for herbs, succulents, or seedlings. It fits standard E26/E27 sockets, often requiring a simple adapter for Indian E27 holders. Unlike generic bulbs, SANSI's patented COC technology ensures superior heat management and a 25,000-hour lifespan, reducing replacement frequency. Local alternatives may lack specific spectrum control or advanced heat dissipation, leading to shorter lifespans and potential plant stress. ## How to use 1. Ensure your lamp holder is an E26 base or has an adapter for an E27 base, common in India. Verify the holder is rated for at least 10W and compatible with 220-240V mains power. — Check Socket Compatibility 2. Carefully screw the SANSI grow light bulb into the compatible socket. Avoid overtightening. Ensure the fixture is stable and the bulb is securely in place before turning on the power. — Install the Grow Bulb 3. Position the bulb at an appropriate distance from your plants (typically 1-2 feet, depending on plant stage). Use a timer for consistent daily light cycles, mimicking natural daylight hours for optimal growth. — Position and Operate ## Product details | Field | Value | |---|---| | Light Source | LED | | Spectrum | Full Spectrum (400nm-780nm) | | Heat Radiation | Low Infrared Emission | | Serving Size | N/A (Light Bulb) | | Cost per use | 25,000 hours lifespan — ₹0.058 per hour (based on average daily use) | | Recommended Use | Indoor plant growth, seed starting, vegetative and flowering stages | | Placement Distance | Close-range exposure safe due to low heat radiation | | Socket Compatibility | Fits E26 base; requires adapter for Indian E27 holders | | Voltage Compatibility | AC 90-132V (US standard); requires adapter for Indian 220-240V mains | | Brand | SANSI | | Model Name | C21-GE26-10W | | Product Type | Growing Light Bulb | | Bulb Shape | A19 | | Base Type | E26 | | Color | White | | Pattern | Solid | | Material | Ceramic | | Item Weight | 0.1 kg (0.22 lb) | | Item Dimensions | 7.8 cm x 7.8 cm x 9.8 cm (3.07 in x 3.07 in x 3.86 in) | | Voltage | 100-132V AC (compatible with Indian 220-240V mains via adapter) | | Wattage | 10W | | Incandescent Equivalent | 150W | | Light Color | 4000K Daylight | | Color Rendering Index (CRI) | 95 | | Lumens | 900 lm | | Beam Angle | 60 degrees | | PPF | 16.8 µmol/s | | PPFD @ 1FT | 97.91 µmol/s/m² | | Efficiency | 1.68 µmol/J | | Lifespan | 25,000 hours | | Certifications | ETL Listed, V0 Flame Retardant, WF2 Anti-Corrosion | | Usage | Indoor | ## Frequently asked questions ### Will a US grow light bulb work in an Indian light socket? US screw-base grow bulbs like this SANSI model (E26) generally thread into Indian E27 holders, often requiring a simple adapter. Crucially, check the voltage rating.
