About Us
Harmony ELS is a lighting company that designs and manufactures LED luminaires in Beylikdüzü, Istanbul. It was founded in 2025; our team has over 10 years of experience in the lighting industry.
Alongside our catalogue products we manufacture luminaires in custom sizes and shapes: L, Y, S, hexagonal, triangular, ring and free-form linear luminaires are built one by one in our workshop to the architect's drawing. We handle the whole job, from lighting calculation to manufacturing and installation support.
- What do we make?
- Recessed, surface-mounted, pendant, track, linear and decorative linear luminaires for indoor spaces; bollards and street luminaires for outdoor areas; industrial luminaires and emergency lighting products.
- Product catalogue
- Engineering
- LED module (PCB) design, integration of DALI, 1-10V and Triac drivers and thermal design are carried out in-house. Wattage, colour temperature, beam angle and size are adapted to each project.
- Electronics & components
- Design and consultancy
- With illuminance calculations, luminaire layouts, energy analysis and installation support, we plan the lighting before choosing the products.
- Design and consultancy
- Quality
- Technical values are documented in the datasheets; photometric, thermal and electrical tests are part of the quality process.
- Quality and certificates
How does a project run?
- 1
Brief and survey
We clarify the requirement from the architectural drawings (DWG/PDF), ceiling height, use of the space and budget. In existing buildings an on-site survey is possible.
- 2
Lighting calculation
Luminaire type, wattage and quantity are calculated from the target illuminance (lux), glare (UGR) and uniformity of the space, and a layout is prepared.
- 3
Product configuration
Wattage, colour temperature, beam angle, finish, size and control system (DALI, 1-10V, Triac) of the selected luminaire are set for the project.
- 4
Manufacturing and testing
Housing, LED module, driver and optics are assembled in our workshop in Beylikdüzü; luminaires are burn-in tested before shipment.
- 5
Delivery and support
Mounting details and wiring diagrams are shared with the installer; technical support is provided during commissioning and after sales.
