What types of LED bulbs are available?
LED bulbs come in many varieties. Their shape affects how they distribute light and where they work best. Classic shapes, such as standard or candle bulbs, replace incandescent and halogen bulbs in open fixtures. They emit light in all directions.
Reflector bulbs, often labeled R50, R63 or R80, direct light forward. They work well in ceiling or recessed spotlights for highlighting features or illuminating pictures. One example is the reflector bulb.
Filament LEDs mimic the look of traditional filaments. They add a decorative touch and are often used in exposed fixtures. Their light output is somewhat lower than that of modern Chip-On-Board LEDs, but their appearance is the main attraction.
Specialty bulbs, such as grow lights or bulbs for industrial lighting, have a light spectrum optimized for a specific purpose. They are not designed for general home lighting.
Classic replacement bulbs
These bulbs are designed to replace traditional light bulbs directly. They fit existing sockets and provide similar or greater brightness while using significantly less energy. Make sure you choose the right base type (E27, E14, GU10, etc.).
Reflector and spotlight bulbs
These bulbs produce a focused beam of light. The number in the name (e.g., R80) often indicates the diameter in millimeters. PAR bulbs have a pre-shaped parabolic reflector housing that directs light precisely.
Tip: Plan your lighting around the effect you want. Use reflector bulbs for targeted accents and general-purpose bulbs for overall room lighting. Combining both can create a welcoming lighting scheme.
The most important buying criteria compared
Compare LED bulbs using objective specifications. Wattage alone tells you very little. Modern LEDs produce plenty of light while using very little power.
Light output in lumens (lm): This is the most important figure. It indicates the bulb's overall brightness. 400-600 lm is enough for a cozy reading nook. Main room lighting requires 1000-1500 lm or more.
Color temperature in Kelvin (K): This determines the color of the light. Warm white (2700-3300K) feels cozy. Neutral white (3300-5300K) is practical. Daylight white (from 5300K) looks bright and energizing.
Color rendering index (CRI/Ra): A value above 80 is good, while above 90 is very good. The higher the Ra value, the more naturally colors appear under the light. This matters for closets, dressing tables and artists' studios.
Switching cycles and dimmability: How often can you turn the light on and off? Quality LEDs can withstand hundreds of thousands of switching cycles. Dimmability is an added feature that not every model supports.
Base and shape
The base must fit the socket in your light fixture. E27 is the large screw base, while E14 is the small one. Pin bases such as GU10 or G9 are common in spotlights and recessed lights. The shape (bulb, candle, round or reflector) determines how the light spreads throughout the room.
Lifespan and warranty
Lifespan is measured in operating hours. 15.000 hours is standard, while 25.000 hours indicates high quality. Check the manufacturer's warranty. It can show how confident the supplier is in its products.
Warning: Avoid cheap products without a recognizable brand or CE marking. They may flicker, render colors poorly or fail early. Any upfront savings can be offset by a shorter lifespan and poor light quality.

Our selection of LED bulbs is extensive. Find the right model for every application.
Note: Availability of specific models may change. LED technology is developing rapidly. Focus on the key criteria described here and you can still find an equivalent or better product when you shop later.
The Right Bulb for Every Application
Choose LED bulbs to suit each application. The right choice improves comfort and energy efficiency.
Living rooms and bedrooms: Warm white (2700K) bulbs in the standard GLS shape or decorative filament LEDs are popular choices. Choose dimmable models to adjust the mood. Low to medium brightness is usually sufficient.
Kitchens and bathrooms: Choose neutral white light (4000K). It creates a clean feel and helps you stay focused. Above sinks or mirrors, narrow-beam reflector bulbs or spotlights provide bright illumination with minimal shadows.
Home offices and workbenches: Daylight white or neutral white LEDs with high lumen output and excellent color rendering (Ra >90) are ideal. They reduce eye strain and make colors look more natural.
Hallways and staircases: Long-lasting bulbs that can withstand frequent switching are important here. Models that work with motion sensors or have integrated sensors save even more energy. Choose warm white or neutral white light.
Special applications
For display cabinets, pictures or architectural lighting, directional reflector bulbs are a great choice. Make sure the beam angle is right for the application. A narrow angle (e.g. 25°) creates focused accents, while a wider angle (e.g. 60°) illuminates larger surfaces.
LED Lighting Trends and Developments for 2026
LED technology continues to evolve, with new developments emerging all the time.
Human Centric Lighting (HCL): Bulbs that automatically adjust their color temperature and brightness throughout the day. They are designed to support wellbeing and the sleep-wake cycle. These smart systems are becoming more affordable for home use.
Even greater efficiency: Efficiency, measured in lumens per watt, continues to improve. That means more light for the same energy consumption, or the same amount of light using even less energy. The limits of what’s possible continue to be pushed.
Integrated smart home functions: Bulbs with built-in Wi-Fi or Zigbee connectivity that do not require a separate bridge. App and voice control are becoming standard in higher-end models.
Sustainability: There is an increasing focus on recyclable materials, longer service life and repairable designs. The circular economy is making its way into lighting technology.
Care and Disposal of LED Bulbs
LED bulbs are easy to maintain. Clean the glass or plastic housing only when the light is switched off and has cooled down, using a dry, soft cloth. Do not use chemical cleaners.
Faulty LED bulbs must not be disposed of with household waste. They are classified as waste electrical and electronic equipment. Take them to a retailer’s collection point or a recycling center. This helps recover valuable raw materials and ensures hazardous substances are handled properly.
Store spare bulbs in a dry place, away from extreme temperatures. This helps preserve their full service life.

Frequently Asked Questions
- Which light color (color temperature) is best for each room?
- Warm white (2700-3300K) creates a cozy atmosphere in living rooms and bedrooms. Neutral white (3300-5300K) is a good choice for kitchens, bathrooms and workspaces, where clear visibility and focus matter. Daylight white (from 5300K) is used in workshops or for tasks that require a high level of concentration.
- What do lumens (lm) tell you about an LED bulb?
- Lumens measure luminous flux, or the total amount of light emitted. The higher the lumen value, the brighter the LED bulb. Compare lumens rather than wattage. An old 60W incandescent bulb produces approximately 800 lm. Check how much light your room needs.
- Are all LED bulbs dimmable?
- No. Only LED bulbs specifically marked as dimmable can be dimmed. Your dimmer must also be compatible with LED technology. Conventional trailing-edge dimmers may cause flickering or fail to work. Check that the bulb and dimmer are compatible before buying.
- How long does a high-quality LED bulb really last?
- High-quality LEDs often last 15,000 to 25,000 operating hours. At an average of 3 hours a day, that equates to 15 to 25 years. The service-life rating (L70 or L80) indicates when the light output falls to 70% or 80% of its initial value.
- What’s the difference between an E27 and an E14 socket?
- The difference is the size of the screw base. E27 (27 mm diameter) is the standard for ceiling and floor lamps. E14 (14 mm) is the smaller base, typically used in chandeliers, bedside lamps or some uplighters. Check which socket your light fitting requires before buying.
