This is a required orientation before going on to LED-101 to familiarize you with LEDs , this forum and to get your books and assigned seating. ..no ..just kidding.
my question is about LED positioning and if theres any adavantage to using a convex /concave surface like this dish strainer for mounting the 5mm ones..

(pardon the food stains...it was in my sink.)
it seems to me that since the 5mm are narrow beam concave side could help focus a tight beam or no? maybe a curvature adjustment experiment while in use by slowly tightening the housing lens down with the disk backstopped somehow.
has anyone drilled the brittle plastic reflectors
for mounting the LEDS paralel to the housing lens rather than outward perpindicular so the beam bounces off the reflector?
conversley, using the convex side of the disk will make for a better overall room light speading it much wider than flat would.
on my big lens 6v hand lantern i dont want to
pack a full cluster but i was thinking of 3-4
single or double rows radiating from center.
3 rows on a concave surface would look neat i bet sorta like a galactica space fighter launch tube..or a hyperspace gate from Babylon5.
