Gains would be a bonus and not my main goal. I’d like to convert whatever lights I can over to neutral white. I clamped the LD10 in a bench vice between rubber material. It was cut from a home depot thin floor mat. I wrapped the same material around the head and used an adjustable wrench that has teeth. Came off pretty easy. My LD01 was quite easy also. So far I have yet to get the PD35 and four sevens Quark Pro apart. Those things are stuck on pretty good. Even tried heat as other members have suggested but no go.
