I am currently using an olympus 5050 in the olympus PT015 housing with Inon 180 strobe. My question is a want a good dive light that is small and powerful for daylight use and night time use. I want to mount it on my strobe arm on a retractor that I can use for looking in dark places and holes. I currently have an Ikelite, but it is not powerful enough in the daylight. I would appreciate any help in this matter.
