I have the 1w LED
and it works well, but unfortunately for sw
enthusiasts it tends to stick quite often. Positioning can be a pain because a single lamp is just enough to illuminate a 20g IMO
. The 1w attaches by either suction cups or slide within the tracks of the aqualight (same as you would attach the legs). The 3/4w attaches by a spring clip, but I have no idea how well it positions. My next purchase, maybe, in the coming weeks will be the aqualight lunar series, which has two 3/4w LED
's. I just hope they are satisfactory in brightness compared to the 1w. Their possible downfall might be the placement of their LED
's, which isn't my preference.
