Frequently Asked Questions

Will this bulb work with my existing dimmer switch?
The S29810 is dimmable and compatible with most standard dimmable LED dimmer switches. However, not all dimmers designed for incandescent bulbs are compatible with LED loads — if you experience flickering, buzzing, or limited dimming range, replacing the dimmer with one rated for LED use will resolve the issue. Check your dimmer manufacturer’s compatibility list for best results.

Can this bulb be used in an enclosed fixture?
Yes — the S29810 is rated for use in enclosed fixtures. Many LED bulbs are not enclosed-fixture rated because heat can build up inside sealed luminaires and shorten LED life; the Satco S29810 is specifically approved for this application.

What is CRI 80 and does it matter for my application?
CRI (Colour Rendering Index) measures how accurately a light source renders colours compared to natural daylight on a scale of 0–100. A CRI of 80 is considered good and is suitable for most general-purpose residential, commercial, and task lighting. For applications where accurate colour discrimination is critical — such as painting, medical examination, or retail display — a higher CRI (90+) bulb may be preferred.

How does the 25,000-hour rated life compare to incandescent bulbs?
A standard 75W incandescent bulb typically has a rated life of around 750–1,000 hours. At 25,000 hours, the Satco S29810 lasts approximately 25–33 times longer, significantly reducing replacement frequency and long-term lamp costs — in addition to using 85% less energy than the 75W incandescent it replaces.
