Sports Facilities Floodlights: Metal Halides vs Induction vs LED

In this video we analyze in detail three types of floodlights used in sports facilities: Metal Halides, Electromagnetic Induction and LED. We compare their technical characteristics and performance to find the best solution.

🔍 Technical analysis of floodlights:

✔ Metal halides – Technology based on an electric arc in a gaseous mixture of metal halides. Efficiency between 75-100 lm/W, but with light emitted at 360°, reducing overall efficiency. High decay of luminous flux (20% after 2,000 hours) and long restart times (10-15 minutes).

✔ Electromagnetic induction – Electrodeless system, based on noble gases ionized by an electromagnetic field. Efficiency comparable to metal halide (65-90 lm/W) and 360° diffused light with loss of efficiency. Very long life (up to 100,000 hours) with low decay (20% after 90,000 hours). No flickering or glare, with the possibility of dimming the light.

✔ LED – Semiconductor technology with directional emission, very high efficiency (180-200 lm/W), duration between 35,000 and 50,000 hours and possibility of dimming. It doesn’t have flickering problems but needs good heat dissipation to avoid degradation of the chip.
