LEDs – the abbreviation stands for “Light Emitting Diode” or “Light Emitting Diode”. These electronic semiconductor devices convert significantly more energy into light than heat. Compared to traditional light bulbs they are enormously economical and environmentally friendly.

• 20.000 – 100.000 hours
• after that the bulb doesn’t turn off but significantly decreases its brightness after time

• E14 & E27
• G4, G9, GU4, GU5.3, GY6.35, GU10
• R7s halogen rods
• PAR30 & PAR38
• AR111 & G53
• T8 tubes and other versions

• light source with no UV and infrared components
• extremely small size and thus applicable in many fields
• the light can be scattered with lenses and diffusers
• high light output with low power consumption (lm / W)

• all colors possible from cold white 6000K warm white 2500K to extra
• neutral warm light can be reached at 3000K

the light bulb must be designed for dimming

Also referred to as “compact fluorescent lamp”. An energy-saving lamp defines as any energy-saving bulb with a better energy efficiency than conventional bulbs. They have an integrated electronic control gear (ECG).

up to 10.000 hours

• E14 & E27
• G9, GU10
• R7s halogen rods
• PAR30 & PAR38
• T8 tubes and other versions

• efficiency of fluorescent lamps installed in more compact forms such as E27, E14, etc.
• thermal output is 5 times as efficient as an old light bulb with the same light output (lumens)

all colors possible from cold white 6000K warm white 2500K to extra

the light bulb must be designed for dimming

Bulbs that are working on a low voltage basis operate with a 12V transformer. Their architecture is similar to the old light bulb technology but a with halogen-gas. The advantage of the low voltage protection is obvious. It is basically allowing humans and animals to touch it and can therefore be used where standard 230V voltages are problematic, e. g. in bathrooms.

up to 3.000 hours

• GU5,3 & GU4
• G4 & GY6,35 (the numbers stand for the base spacing of the individual socket contacts in mm)

• 2-5 times longer lifespan than old light bulbs
• dimmable (reverse phase control dimmer)
• compact design enable sophisticated lighting solutions
• use in damp rooms without problems (when used correctly)
• different beam angles available (spot effect)

most common colors: 2500-3000K

the bulb is dimmable as standard

banned since September 2016 in accordance with EU regulation which means only the stock models with an energy efficiency class of A-B are still available

High-voltage halogen bulbs are thermal light spots which can be directly connected to 230-240V, similar to convential bulbs.

up to 2.000 hours

• E14 & E27
• G9, GU10/GZ10
• R7s
• B15d

• no transformer required
• dimmable (phase control dimmer)
• approximately twice as long lifespan as a conventional bulb

most common colors: 2800-3000K

the bulb is dimmable as standard

banned since September 2016 in accordance with EU regulation which means only the stock models with an energy efficiency class of A-B are still available

It’s a light bulb which produces light with a wire filament heated to a high temperature of 2.500°C by an electric current passing through it, until it glows. The lamp interior is filled with gas which prevents a burning of the filament.

up to 1.000 hours

E14 & E27

• No transformer required
• dimmable (phase control dimmer)

most common colors: 2400-2900K

the bulb is dimmable as standard

banned since September 2016 in accordance with EU regulation which means only the stock models with an energy efficiency class of A-B are still available
