What Customers Ask Most
Choose lighting based on your space.
LED for everyday use, smart lighting for convenience, outdoor lighting for safety, and decorative lighting for atmosphere.
For most rooms, 800–1600 lumens works well.
Higher lumens = brighter light.
2700K–3000K = warm & cozy
4000K = neutral & clean
5000K+ = bright & daylight
Solar lights are great for pathways, gardens, and ambiance.
For strong brightness, choose high-lumen models.
