Are LED bulbs dimmable?
Some LED bulbs are dimmable, while others are not. Always check the product packaging or product page on the Cree Lighting website to verify dimmability and ensure you are using a compatible dimmer for optimal performance.
What is the difference between bulbs rated for wet vs. damp locations?
- Wet-rated bulbs are fully sealed and designed to withstand direct exposure to water, making them suitable for outdoor or indoor use where water contact is likely (e.g., exposed outdoor fixtures, showers).
- Damp-rated bulbs can tolerate moisture and humidity but must be protected from direct water exposure. These are ideal for covered outdoor areas (e.g., porches) or bathrooms with adequate fixture protection.
Do LED bulbs generate heat?
Yes, LED bulbs do produce some heat, but significantly less than incandescent, halogen, or CFL bulbs. The heat is typically dissipated through an integrated heat sink. Always allow bulbs to cool before handling and follow safe handling practices.
Can LED bulbs be used in enclosed fixtures?
Only if the LED bulb is specifically rated for enclosed fixtures. Enclosed environments can trap heat, reducing performance or lifespan. Additionally, fixtures with rubber gaskets that seal tightly may restrict necessary airflow. For best results, use only bulbs marked as “enclosed fixture rated” and avoid rubber-sealed housings.
Why are only some bulbs working in my fixture?
This typically indicates a faulty bulb or socket. To diagnose, test the non-working bulb in a different, known working socket. If it fails there, the bulb is defective. If it works, the issue lies with the original socket, which may require inspection or replacement.
Is it safe to use a cracked light bulb?
No. A cracked bulb is a sign of physical damage, and continued use may pose safety risks. LED bulbs may continue to function when cracked, but we recommend returning or replacing any damaged product. Traditional technologies (incandescent, halogen, fluorescent) should not be used if cracked under any circumstance.
Can LED bulbs be used in ovens?
No. LED bulbs are not designed to withstand the extreme heat inside ovens. For oven applications, use only incandescent or halogen bulbs that are rated specifically for high-heat environments.
