You can buy silver reflectant spray paint and make your own reflector insert or enhance the one you've got. Places like Ace hardware sell it. It might be good to copy or reuse a reflector from an old light...factoring in heat.
My guess is that you'll need to narrow and lower the beam. Be sure you have a good seal on the housing otherwise water seeps in.
