The inventive illumination device includes a light assembly frame having a first longitudinal extending wall, a second longitudinal extending wall, a first upper beam, a first lower beam, a first wall end, a second upper beam, a second wall end, and a second lower beam providing an open top and an open bottom. A first end cap having a first rectangular shaped insert is disposed in the first wall end. A second end cap having a second rectangular shaped insert is disposed in the second wall end. A removable light assembly is positioned in the open top. The light assembly frame may be releasably engaged to a variety of supplemental support components proximate to a body of water.

A solar-powered outdoor plant supplemental light system designed to enhance plant growth in shaded areas is disclosed. The system comprises a stable base, a telescoping arm adjustable in length via a knob, and a detachable solar-powered lighting unit. The lighting unit includes a housing with a solar panel that converts solar energy into electric power, which then illuminates a plurality of LED lights directed at the plants. The system features a weatherproof LED cover, a timer dial for setting light exposure duration, a battery power indicator, an integrated battery, and a solar panel connector for additional power. A sensor adjusts the lighting unit towards sunlight and automates the LED operation at dusk and dawn. The LEDs can emit blue or red light to support different plant growth stages and/or plant varieties.
