- 1000 lumen output
- Dusk till dawn lighting (8 - 10 hours)
- Made entirely from aluminum
- High price
MicroSolar FL5-B is one of the bet solar powered floodlights on the market as this light has the power output of 1000 lumens and it can work continuously for 8 to 12 hours but the solar panel is able to recharge the Lithium ion battery in a single day.
Looking at this fixture from the design perspective it is a real masterpiece of engineering as it is made entirely from aluminum and it has 180 LED diodes that are enclosed in a waterproof seal under impact resistant glass shield. This fixture is made from two separate parts where one is the light itself but the other is the solar panel that also has a light meter that detects weather it is daytime or nighttime and weather to turn the light on or off. The bulb head itself has the dimensions of 19.2 inches x 12.1 inches x 5.2 inches (48 cm x 30 cm x 13 cm) but the whole product weight is around 10 pounds (4.5 kg) so it is not the smallest or the lightest floodlight but considering the performance statistics it is well worth the extra space and weight. If you look at the light fixture itself you will see a completely weatherproof aluminum housing that has the IP65 rating and that means it can be used on ship decks and will work under strong water jets and it will also sustain limited ingress dust particles. At the back there is a mounting arm also made from aluminum that is attached to both sides of this light so it can be maneuvered up and down to get the most appropriate lighting pattern. This fixture is also held together with 4 screws so if anything goes wrong you can easily dismantle it and change the battery or other parts.
As the functionality goes this solar floodlight is one of the strongest lights that you can get as it will give out 1000 lumens from a 10 watt power input so that means those LED diodes give around 100 lumens per watt efficiency and that is a really great number. 1000 lumen output means that this light will be as bright as a 75W incandescent bulb and that is enough to light up your whole backyard with a decent amount of light. But the power output is just the beginning as this light also has a 8000 mAh internal rechargeable Lithium ion battery that will allow this light to work from dusk till dawn or approximately 8 to 12 hours with a fully charged battery. Because of this performance I can strongly say that this light is one of the best performers in the flood light niche because no other light can produce 1000 lumens and work all night light without reducing the light output. This Lithium ion battery is built inside the bulb head itself and it will work for at least 2 years before those charge and discharge cycles will become shorter and shorter but know that after this time you can easily change the battery and continue using this solar floodlight.
Then there is the solar panel that is a polycrystalline panel capable of producing up to 20W of power output in full sunlight. That means that this solar panel will be able to recharge your solar floodlight in no time and you will always have a fully recharged battery to light up those 180 LED diodes. This solar panel can be wall or ground mounted and it has a waterproof 5 meter wire so you will be able to mount it in a 16.4 feet (5 meter) diameter from the light fixture itself. Because this solar panel also has a light sensor it will signal the light fixture to turn off when the morning comes and you can also use the light without the panel if you disconnect it.
Overall this FL5-B floodlight is one of the best lights that you can buy and the extra price is well worth it as the performance and build quality is excellent!
