Energy saving up to 70% compared to traditional 36 W fluorescent lamps.
Dual operation mode: can be used with old ballasts (14 W) or directly at 230 V (11.3 W).
Long service life – up to 5–10 times longer than fluorescent lamps.
Stable light – flicker-free, suitable for long-term use and compatible with sensors.
Cold resistant – works perfectly in refrigerators, warehouses, or unheated rooms.
Eco-friendly – mercury-free, recyclable packaging, RoHS compliant.
Applications
For home users: garages, basements, kitchens, workshops – replaces old fluorescent lamps, saves energy.
For engineers: suitable for warehouses, supermarkets, laboratories, schools, production lines – where economy and reliability matter.
For electricians: easy installation – can be used with LED starter or direct connection bypassing ballast; ideal for mass modernization.
For the food industry: shatterproof glass allows use according to HACCP requirements.
Pros
Saves energy – replaces old 36 W fluorescent lamp with only 11–14 W consumption.
Very long service life – up to 100,000 h.
Stable, flicker-free light, eye-friendly.
Fast start – compatible with motion sensors.
Versatile – works both with EM ballasts and direct 230 V.
Eco-friendly – mercury-free, EU compliant.
Works reliably in cold conditions (down to -20 °C).
Cons
In EM mode consumes more power (14 W) than in direct mode (11.3 W).
Higher price than basic fluorescent lamps but pays off through energy savings.
Not compatible with electronic ballasts (ECG).
Operating Modes
Direct 230 V (by-pass, without ballast): ~11.3 W, highest efficiency (155–160 lm/W), requires rewiring (LED starter, ballast removed).
Through EM ballast: ~14 W (due to ballast losses), slightly lower efficiency, but convenient – simply replace old fluorescent lamp with LED + LED starter, no rewiring needed.
Summary
The LED T8 EM Superior 1200 mm is a reliable and modern alternative to old T8 fluorescent lamps. It significantly reduces energy costs, ensures stable light output, works in cold environments, and lasts 5–10 times longer than traditional lamps.
For households – lower electricity bills and fewer replacements.
For engineers – a dependable solution for large lighting systems.
For electricians – easy installation, suitable for both ballast and direct connection setups.Illustrative image may have been created using AI.

Based on their quantity, you can choose a light fixture that will properly illuminate the entire room.
How to choose the right number of lumens in a light fixture?
450-800 Lm are used for decorative lighting, table lamps, bedside lamps. Light fixtures with up to 800 Lm brightness are suitable for creating a cozy environment.
800-1100 Lm are used for small rooms (bedrooms, hallways).
1100-1600 Lm are used for medium-sized spaces such as dining rooms, kitchens, bathrooms, and children's rooms.
1600-3000 Lm are used for large rooms (shopping malls, entire 11-18 square meter rooms).
Light fixtures with more than 3000 Lm emit very bright and intense light. They are used in workshops, garages, and industrial spaces.
To accurately calculate the required number of lumens for a room, use the formula:Lm = 150 lx * 4π * (distance in meters to the surface)²

3 main types of white light:
Warm white (2700 - 3000 K)
Neutral white / daylight (4000 - 4500 K)
Cool white (5000 - 6500 K)
How to choose the right light color temperature:2700 - 3000K creates a cozy atmosphere in a room. Used in spas, hotel entrances, living rooms, and bedrooms.
4000 - 4500K is used in commercial, retail, office spaces, garages, medical buildings, as well as bathrooms, kitchens, and workrooms.
5000 - 6500K is suitable for lighting workshops, operating rooms, or other areas where attention to detail is important. Also suitable for outdoor lighting, modern interiors, and their accents.
