Solar Outdoor Flood Lighting
Solar lamps can even fulfil your outdoor flood lighting needs. To do this, of course, they need a bit more power than your average solar lamp. And they need more flexibility as well to be directed exactly where you want to go. For both these reasons, the standard design for solar garden and path lights won't do here.
In that standard design, you have a solar panel forms the flat cap to a stationary light. But to power a sufficiently bright flood light, that panel would have to be quite large. And adjusting the flood light to shine in the desired direction might turn that panel away from it's source of energy, the sun.
So typically, solar outdoor flood lighting involves a larger solar panel that is separate from the light or lights that it powers. This panel can be positioned for optimum sun exposure during the day. It should swivel freely in any direction to make this task easier. It is connected to its light(s) by several feet of weatherproof cable. Such an arrangement with 20 feet of cabling should prove more than adequate for most designs.
This style of solar panel can often connect to two or three flood lights. This gives you more versatility in positioning the lamps for optimum illumination.
The lamps themselves are standard floodlights. They install in the ground via a simple stake or can be attached to walls and railings via a surface mounting bracket. Either way, these lamps should be fully adjustable so that the light goes where you want it to and nowhere else. The "bulbs" themselves will often be white LEDs to gain optimum illumination from the energy that is provided to them.
There are some solar flood lights that come attached to the panels that power them. This avoids the hassle of placing and burying cabling. A simple example will be ground mounted via a stake or put on wall or railing with a mounting bracket. The lamp will be attached to the mount and should be fully adjustable to shine in any direction. The solar panel is attached via a separate adjustable mounting to the top of the lamp. With a little work, you can adjust the lamp the way you like and then adjust the panel so that it sits on top of the lamp at the proper angle. A minor inconvenience is that any time you adjust the angle of the lamp, you'll have to readjust the solar panel as well so that it once again points in the proper direction.
Another version is simply ground mounted via a stake and has solar panels at the top pointing straight up. The lamp hangs off the side of the panels and can be positioned. to shine at various angles up onto shrubbery and trees or down onto walkways or flowerbeds.
You can even find solar floodlights hidden inside artificial rocks. This sort of floodlight lacks the versatility of the other designs. The solar panel sits flat on top and is not adjustable. The light itself is not adjustable either. Your sole means of aiming the light is by positioning the "rock".
