LED technology is already very advanced, but not yet to the point where floodlight halogen lamps can be replaced. Even if it were possible in the short term to place LEDs in the form of a halogen rod in such a way that cooling and light emission are guaranteed, the luminous fluxes currently possible are too low. At present, very good LEDs can achieve luminous fluxes of around 60 lumens per watt. read more
