Light Bulbs - Other FAQs
How do I choose between GU10 and MR16 for spotlights?
Start with your fixture. GU10 uses a twist-lock base for mains-voltage fittings, while MR16 describes a reflector size around 2 inches and commonly pairs with a GU5.3 pin base and low voltage. Some bulbs have the MR16 shape with a GU10 base. Check both the base type and the voltage your fixture expects. If your existing bulb twists and locks, it’s likely GU10. If it has two pins and uses a transformer, it’s likely an MR16 with a GU5.3 base.
Is a 15W LED like the Airam GU10 bright enough to replace old halogens?
Yes, 15W LEDs are typically designed to outperform older halogens of much higher wattage. You’ll get strong, focused light with far less heat and energy use. For task-heavy spots like kitchens, a 15W LED GU10 is a great upgrade, delivering crisp illumination while keeping bills in check.
What’s the advantage of amber or smoke glass on decorative bulbs?
Amber glass adds warmth and softens brightness, creating a cozy, vintage vibe—perfect for evenings. Smoke glass lends a modern, moody look and tames glare. Both finishes help hide LED components when the bulb is exposed, so your fixtures look designed rather than utilitarian.
Do I need a special dimmer for dimmable LED bulbs?
It’s best to use a dimmer rated for LEDs. Traditional dimmers were built for incandescents and can cause flicker or buzzing with LEDs. Check the dimmer’s compatibility list or opt for smart bulbs that dim via app or voice control without relying on a wall dimmer.
Where should I use ultra-low-watt bulbs like 1W or 0.5W E14 pears?
Use them where ambience matters more than raw brightness: hallway night lighting, bedside sconces, accent shelves, or display cabinets. They’re excellent for layering light—let brighter bulbs handle tasks, then switch to these for a calm, evening atmosphere.
