Frequently Asked Questions
What is the best type of light for a low ceiling?
What is the best type of light for a low ceiling?
A flush mount ceiling light is the best and most popular choice for low ceilings (typically 8 feet or less). Because they mount directly to the ceiling surface, they maximize vertical space, prevent anyone from bumping their head, and make the room feel more open.
How do I choose the right size flush mount light for my room?
How do I choose the right size flush mount light for my room?
A common guideline is the "Length + Width" rule. Add your room's length and width in feet, then treat that number as the ideal diameter in inches. For example, for a 10-foot by 12-foot bedroom, you would add 10 + 12 = 22. This means a flush mount light around 22 inches in diameter will look proportional. For long hallways, consider using multiple smaller flush mounts.
What is an integrated LED flush mount light?
What is an integrated LED flush mount light?
An integrated LED flush mount light has the LED light source built directly into the fixture. You do not use separate light bulbs. The primary benefit is a very long lifespan (often 25,000-50,000 hours) and high energy efficiency. They are a "set it and forget it" solution that won't require new bulbs for many years.
Can I put a flush mount ceiling light in a bathroom?
Can I put a flush mount ceiling light in a bathroom?
Yes, but you must choose a fixture that is rated for its specific location. A flush mount light labeled as "damp-rated" is suitable for most bathrooms with a shower or tub (as long as there is ventilation). If the light will be inside the shower, it must be "wet-rated."
How are flush mounts different from semi-flush mounts?
How are flush mounts different from semi-flush mounts?
A flush mount light sits directly against the ceiling with no gap. A semi-flush mount light hangs just below the ceiling (usually 4-8 inches), creating a small gap. This gap allows light to shine upwards and bounce off the ceiling, creating a softer, multi-directional glow.
