I also added 5 homemade beer can reflectors, fresh off the assembly line lol three 12oz that fit 23 w cfls perfectly, one 24oz and one 16oz that both worked out great for a couple of my 42 watt bulbs...here is a pic of one of the 12oz...I'll be making more in the future for sure! Tested it holding a bulb a couple feet away from my bedroom wall which is white and it made a very noticeable difference with the reflector on vs without a reflector
