U got a reflector installed? leaks can be a killer
1- kill ambient lighting.
2- reflector - pro and look into a precondenser. Helps both distribution and lumens.
3- distances to everything.
Moving my reflector back only 1cm, I had vignetting and loss of lumens - MAJOR loss.
So within 2 mm you're good. Otherwise, you're off.
Also, light hitting the triplet makes it the on the other side. To improve, you'd need a bigger triplet. Less light loss.
But the standard triplet is good enough to get a decent projection.

Then, if you choose to go that way :
ag layer removal(helps differently from panel to panel)
changing to a brighter bulb.
Happy tuning!
