## Description

GROW LIGHT BULBS

Review: It was defective
Review: Lo compré porque en mi casa no entra casi nada de luz y me gustan mucho las plantas, algunas se me murieron y las pocas que quedaban dejaron de crecer, se etiolaron y en general no se veían bien. Ya llevan aproximadamente 20 días y ya presentan retoños, se ven más verdes, con brillo y las que tienen manchas más claras se están resaltando. Solo hay que tener cuidado de no exponerlas demasiadas horas porque se pueden quemar un poco las hojas o como en mi caso, que necesitaron hacer el cambio más progresivo. Lo único que no he podido evaluar es el consumo energético, pero vale la pena ver bien mis plantitas

## Features

- 4000K DAYLIGHT: Imitate the solar spectrum, customize a more ideal full life cycle full spectrum supplementary light program, covering the entire visible spectrum of 400nm-780nm; Color rendering index Ra is close to 100, infinitely close to natural light, suitable for every cycle of plant growth, effectively promotes plant growth, and improves crop yield and quality
- SECONDARY OPTICAL DESIGN: PPF: 65.6 umol/s, PPFD: 265.58 μmol/s/㎡ @ 1ft. Through the lens for secondary scientific light distribution, improve light utilization, give plants more supplementary light, and improve light bulb lifespan to 25,000 hours
- PATENTED COC TECHNOLOGY: Chip on Ceramic, SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, and directly solder the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, makes the SANSI bulb has higher light efficiency
- SAFE & RELIABLE: The lamp body is made of special ceramic material, and the flame retardant grade reaches V0; the reinforced insulation structure design, no risk of electric shock, is safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable; low IR, less heat radiation, avoiding close Distance exposure burns plants
- GUARANTEES: ETL listed, quality and safety verified, 5-year protection plan

### ⭐⭐⭐⭐⭐ Review
*by T***Z on 30 December 2025*

I’ve been using the SANSI 34W Grow Light for about 4 years now, and it has been absolutely awesome. This light has allowed me to grow massive, healthy plants completely indoors with strong growth, great leaf size, and consistent results year after year. The light output is powerful for its size, energy-efficient, and reliable long-term—I’ve never had issues with it burning out or losing intensity. It’s perfect for houseplants and makes a noticeable difference in plant health and growth, especially if you don’t have ideal natural lighting. If you’re serious about indoor plant growth and want something dependable that actually works, I highly recommend the SANSI 34W grow light. It has more than proven itself over time. 🌱💡. Last week I had to use their customer service for blown bulbs and it was top notch service and hassle free replacement.
