Compare G25 and A15 LED bulbs to find the right shape for your fixtures. Learn key differences and get practical advice for your lighting needs.
Quick Answer
Choose a G25 LED bulb for larger fixtures that can handle its globe shape, and an A15 LED bulb for smaller, more versatile applications. Both offer energy savings and high color accuracy.
Shape and Size Matter
The G25 has a globe shape, which is wider and rounder, making it a good fit for fixtures that show the bulb, like vanity lights or pendant lamps. The A15 has a classic bullet or torpedo shape, narrower and more tapered, which works in many standard lamps and enclosed fixtures.
Before choosing, check your fixture's recommended bulb size. A bulb that is too large may not fit or may look awkward. A bulb that is too small might not provide enough light or fill the space as intended.
Light Quality and Efficiency
Both the G25 and A15 LED bulbs from Feit Electric feature a high CRI of 90+, meaning colors appear more realistic and vibrant. This is especially important in spaces where accurate color matters, like a makeup mirror or a craft room.
They also combine LED technology with filament strips, giving you the energy savings of an LED with the warm, classic look of a traditional bulb. This makes them a smart upgrade from older incandescent bulbs.
Consider Your Fixture Type
If you have a fixture with a visible bulb, such as an open pendant or a wall sconce, the G25's globe shape adds a decorative touch. For enclosed fixtures or lamps with shades, the A15's slimmer profile often fits better and is less likely to be obstructed.
Also consider the base size. While not specified here, always verify the base type (like E26) matches your fixture. This is a common oversight that can lead to compatibility issues.
Trade-Offs at a Glance
- G25: Globe Shape: This bulb is wider and rounder, making it ideal for fixtures that expose the bulb. It offers a decorative, classic look but may not fit in tight or enclosed spaces. Measure your fixture's opening before choosing a G25.
- A15: Classic Shape: This bulb has a narrower, tapered shape that fits well in most lamps and enclosed fixtures. It's versatile but less visually striking in open fixtures. Check the base type and fixture compatibility before buying.
- Light Quality: Both bulbs offer high CRI (90+) for vibrant, realistic colors, so your choice can focus on shape and fit rather than light quality. If color accuracy matters, either bulb will perform well.
