The Rosewill RSL-113 dual-LED solar-charged lighting system is meant to illuminate small areas out-of-reach for installed light fixtures. The LED lamps on this system are not spotlights, meant to replace broad-distance halogen bulbs or flood lamps. While the dual-LED lamps may offer sufficient light for small driveways, they’re better off being focused on localized areas such as: gates, walkways, sidewalks, or an alleyway.
Each 1W LED lamp will create a very bright focused area at the center of its beam approximately 3-feet diameter, with an illuminated dispersion area approximately 15′ in diameter (dependent upon elevation from ground). The LED’s beam is similar to a single-bulb 1200 lumens flashlights, with uneven diffusion. On my installation, the Rosewill RSL-113 was placed on the dark side of my home where no other light sources reach, and when something with a heat signature comes within 30-feet of the PIR sensor then both lamps shine to illuminate an area nearly 30-feet wide with positioned beams.
Appearance is subjective, especially for a product that will likely be installed onto a home, so I’ll cover the fine points. The Rosewill RSL-113 comes in soft-white colored plastic, and with careful masking it can be painted to match the exterior of any area where it’s mounted. I choose not to paint the unit since white contrasts against the dark brown color of my roof eaves, allowing the lighting unit to act as a visible deterrent.
In comparison to glass-bulb flood lamps, the Rosewill RSL-113 kit is far more durable than traditional lighting solutions. The dual-LED system is constructed of high-impact plastic, but it’s not indestructible. If positioned low enough, the unit could be struck destroyed by vandalism. However, under most circumstances the dual-LED lighting system will survive the harshest weather conditions.
As of March 2013, the Rosewill RSL-113 Dual-Head PIR Solar Light Kit sells for $24.99 (NewEgg / Amazon). It comes with three AA 1300mAh Ni-MH rechargeable batteries, which have a lifetime of ten years or longer depending on usage and depletion, and does not require replacement bulbs. Rosewill offers a one-year warranty for the kit, just in case one of the LED lamps has problems or something goes wrong with internal electronics.
The Rosewill RSL-113 solar-charged infrared dual-LED 1000 lumen flashlight system is ideal for several practical applications, especially where no power source is available. Rubber weather seals keep moisture out, allowing the lights to be positioned in exterior location exposed to wet conditions. The lights are bright enough to shine out beyond 30-feet, but work best for confined areas light walkways or gates. The LED lamps met my expectations, and will likely serve my needs for many years before maintenance is required. I recommend the Rosewill RSL-113 solar-charged lighting kit, as it offers excellent value for the money and delivers good overall performance.
