How do I compare LEDs to incandescent/halogen?
Compare lumens (brightness), not watts. Watts tell you energy use; lumens tell you how bright it will look.
What lumens do I need for a room?
As a rule of thumb: bedrooms ~100–150 lumens/m², kitchens/offices ~200–300 lumens/m², task areas higher. If you share room size and ceiling height, we can recommend a target lumen range.
What color temperature should I choose (2700K/3000K/4000K/5000K)?
2700K = warm/relaxing (living/bedrooms), 3000K = warm-neutral (most homes), 4000K = crisp neutral (kitchens/retail), 5000K+ = daylight (work/industrial).
What is CRI and what should I choose?
CRI measures color accuracy. CRI 80 is standard; CRI 90+ is recommended for retail displays, kitchens, makeup/beauty, and anywhere color matters.
Why do some LEDs look “harsh” or cause glare?
Usually due to high brightness concentrated in a small emitting area, clear lenses, or wide beam angles. Look for better optics/diffusers, proper beam angle, and lower glare designs.
Will this LED work with my existing dimmer?
Not always. Dimming depends on the dimming type (TRIAC/leading-edge/trailing-edge/0–10V/DALI). Share your dimmer model and we’ll confirm compatibility.
Can I use smart switches or smart bulbs?
Yes, but don’t double-control. If you use smart bulbs, keep the wall switch always on; if you use a smart switch, use standard dimmable bulbs rated for that dimmer type.
Do LEDs really last 25,000–50,000 hours?
They can, but lifetime depends heavily on driver quality and heat. Better thermal design and higher-grade drivers maintain brightness longer and fail less.
