Standard Light Bulbs
Even with the widespread shift to energy-efficient lighting, incandescent bulbs continue to hold their place in homes and specialty applications. Known for their warm glow, full dimmability, and instant brightness, incandescent light bulbs remain a trusted choice for decorative, appliance, and high-output commercial use.
Are Incandescent Bulbs Dimmable?
Yes, all incandescent bulbs are dimmable and compatible with most standard dimmers. However, we don’t recommend using incandescent bulbs with LED-specific dimmers unless they support multiple bulb technologies. For best results, pair your bulbs with a dimmer that matches the technology type.
Can I Use a Higher Wattage Bulb Than Recommended on a Lamp?
If you're switching to LED, you can use a higher wattage equivalent as long as the actual wattage stays below the fixture’s rating. For example, a 100W LED bulb typically consumes only 15–20 watts. However, you should never use a 100W incandescent bulb in a fixture rated for 60W, as it can cause overheating or fire risks.
3-Way, Appliance, and Rough Service Light Bulbs
Incandescent bulbs are still widely used for:
- Appliances: Appliance bulbs are designed for ovens, refrigerators, and microwaves. Compact, lower-wattage options include 15W and 25W options.
- Ceiling Fans: Use reinforced filaments to endure vibration.
- Rough Service: Built for high-vibration areas like garages and workshops, with durable filaments and shatter-resistant coatings.
- 3-Way Bulbs: Dual-filament bulbs that offer low, medium, and high light levels (e.g., 30/70/100W or 50/100/150W).
Incandescent Bulb Shapes and Sizes
Most household incandescent bulbs come in standard A-shapes like A19 and A21, where the number indicates the bulb's diameter in eighths of an inch.
For higher-output needs, look for PS-shaped bulbs like 300W or 500–1500W versions. These often use a mogul E39 base instead of a standard medium E26.
Where Incandescent Still Shines
- Warm, ambient glow unmatched by LED
- Dimmability across all models
- Low upfront cost for short-term or low-usage applications
- Specialty use in legacy fixtures or appliances
