The actinics (2 x 75W URI Super Actinic VHOs). Reflector is polished aluminum and I'm using acrylic lamp holders (both purchased at Marine Depot). The actinics are angled towards the opposite sides of the tank thanks to Entamacea making me some angled wedges Stainless steel screws mount the reflector to the wedges, and the wedges are mounted to the canopy via wood glue and more stainless steel screws.
