I'm looking for a lens with a maximum diameter of 45mm that produces a 5° beam angle and delivers at least 500 lumens. If this isn't feasible, I'm open to considering a 2x2 lens array with similar specifications but requiring a light output of 800+ lumens. This component is destined for an architectural downlight application, so high-quality light is crucial. Ideally, I need a CRI of 90+ and a color temperature range between 2700K and 3500K, with a preference towards the warmer end of that spectrum.
