ENGINE: Fortimo RATED POWER: 32 W RATED OUTPUT: up to 2000 lm RATED EFFICACY: up to 63 lm/W COLOUR TEMPERATURE: 4000K COLOUR RENDERING: Ra80 BEAM ANGLE: 65 degrees PRICE: Around £600 OUR VERDICT: ★★★★★
This is the state of the art in LED engineering. It delivers 60 lumens a watt, a stonking performance that we have confirmed in our independent tests, making it comfortably Part L2 compliant for use in commercial areas. The optics are superb and the Fortimo engine delivers enough lumens to make it a comparable replacement for a twin 18W CFL downlight. But all this precision engineering comes at a price – one that’ll have to be justified by significant maintenance savings.
