* The luminous flux is already stated including losses in the luminaire (we do not state the luminous flux of the LED chips themselves). The luminous flux intensity depends on the selected color temperature (in kelvins) – the higher the temperature, the higher the luminous flux. [3,000 K = warm white (TB), 4,000 K = neutral white (NB), 5,000 K = daylight white (DB), 6,000 K = cool white (SB)]

LDT data for the LENA Ex luminaire
It is an ideal replacement for linear T5 and T8 fluorescent tubes. It is most commonly used for surface-mounted or suspended ceiling installation, or for wall mounting. It is suitable for both indoor and outdoor use. It is manufactured in three lengths (60, 120 and 150 cm), in a versionwith integrated LED chips.
LENA Ex guarantees long lifespan and significant energy savings. You will certainly appreciate its parameters – up to 50% cost savings on energy compared to its older fluorescent alternative and a lifespan of more than 75,000 hours. Thanks to its high luminous efficacy of up to 128 lm/W, it can efficiently illuminate the space while reducing your costs.
Individual light sources (LED chips) are not visible; the luminaire provides pleasant uniform illumination of the space without the effect of multiple shadows. The luminaire is characterized by accurate color rendering, with a color rendering index above 80.
Other characteristics of the LENA Ex luminaire include dust resistance and high resistance to water splashes and impacts (thanks to the IP 66 rating, perfect sealing of the luminaire is ensured).It has an instant start, does not buzz, and does not flicker.
The luminaire is “photobiologically safe” and belongs to the category “risk-free lighting” – it has no photobiological impact on the human body (skin, cornea) even with long-term exposure. It can also be classified as ecological lighting – it does not contain substances harmful to the environment and does not produce UV radiation. The polycarbonate body of the luminaire is made exclusively of safe materials and even in case of damage, there is no risk.
Component quality, high durability and functionality are the top priorities for these luminaires. LENA Ex is designed for areas with a risk of explosion in group II, category 3 (zone 2, 22). An ATEX certificate is available for environments with a risk of explosion from gases, dust, and flammable vapors.
The LENA Ex luminaires come with a 3-year warranty (extendable to 5 years upon project registration).
