Design and Dimensions


Product advantages
①Integrated molding to achieve good waterproof performance.
②Leaving the liquid surface to quickly restore ventilation.
③The interference fit between the cover and the body solves the problem of the cover falling off.
④The cover is thin and the body is thick, and the sleeve is focused on the sleeve to avoid the risk of the cover falling off or even twisting the column.

Use 2 lamps of the same type, and the lighting time lasts 90min.
