I've used these on all 3 of my Juwel tanks. They just about double the amount of light being delivered into your tank and reduce the amount of light spill out of the tank into the room. The plastic clips that secure the reflector to the lamp will eventually become brittle and break, but Juwel sell replacements at a fairly minimal price. Recommended.
