Circular fluorescent lamp with a diameter of 26 mm MASTER TL-E Super 80, 40W/830, G10q 928027483070

Universal lighting in the form of a closed ring

The MASTER TL-E Super 80 circular fluorescent lamp features a closed ring-shaped design - this solution enables even light distribution in all directions simultaneously. Unlike classic linear fluorescent lamps, the round shape eliminates lighting dead zones and allows for more symmetrical illumination of the space. The external diameter of the ring is 406 mm, and the bulb has a thickness of 29 mm - these dimensions determine compatibility with fixtures designed for this standard.

The model with a power of 40 W and a G10q base (round bayonet base) is suitable for both commercial installations and residential spaces. The manufacturer indicates a wide spectrum of applications including general and decorative lighting - from schools and offices to shops, as well as home interiors and residential areas.

Luminous parameters and color characteristics

A luminous flux at the level of 3200 lm with a power consumption of 40,8 W translates to an efficacy of approximately 78-80 lm/W - an average result for a fluorescent lamp of this type. The color of the emitted light is 3000 K (warm white), which corresponds to the 830 code in the ILCOS classification. The warm color temperature promotes relaxation and the creation of a cozy atmosphere, which is why this lamp often appears in relaxation zones and residential rooms.

The color rendering index CRI 80 ensures decent color reproduction - it is not at the level of professional studio lamps (90+), but sufficient for most general and decorative applications. The manufacturer describes this series as "Super 80", which means improved light quality compared to standard fluorescent lamps - including better color rendering and higher efficacy.

The lamp supports dimming (dimmable: Yes), which allows for the regulation of light intensity depending on the time of day or the activity being performed.

Durability and operating conditions

A rated lifespan of 13 000 hours (at 50% failure) places this model in the standard segment of the compact fluorescent lamp market - typically lasting for several years of use under normal operation. The lamp current is 0,42 A, and the supply voltage is 110 V.

Energy consumption per 1000 hours of operation is 41 kWh, which according to the current EU classification places the product in category G (the lowest energy efficiency class).

Mercury content is 8 mg - a typical amount for fluorescent lamps of this generation. In case of breakage, the manufacturer recommends ventilating the room for 30 minutes and carefully removing fragments using protective gloves into a sealed plastic bag.

Compatibility and safety of use

The G10q base requires a dedicated fixture equipped with a socket of this type - it is not compatible with standard E14/E27 fixtures or pin sockets (e.g., G13 as in classic T8). The lamp is not adapted to low temperatures or to operation without a starter - it requires installation with a standard ignition circuit.

The product does not have an internal reflector or an anti-splatter shield - when installing in areas exposed to mechanical damage, an additional protective housing for the fixture should be considered.

For installers, the information about quick start (quick start) will be important - the lamp does not require a long warm-up time before reaching full luminous flux.
