Betta500

Betta500 powerful, cost effective and rugged solar area/security LED light solution

Applications

Security gates
External parking areas
Dark areas not on the grid
Government buildings for rural areas such as clinics
Schools and border posts
Military facilities
Bill boards.

Betta500 uses 500 LED diodes and has a light distribution of 130degrees. Illumination is 50 lux at 5 meters on the centreline. As a result the demonstrated area coverage per light is approximately 300-400sqm with a distance of 25 meters.

The system makes use of 4 x 22Ah 12Volt lead crystal batteries. These batteries can handle heat of up to 65 degrees C, can be depleted 100% and will take charge thereafter, it recharge 2 to 5 times quicker than other lead acid battery technologies with a life expectancy of 10 years.

The Betta500 mounts on a 6-7 meter galvanized pole with a 76mm or 115mm thickness on the top. It can also be fitted on a wooden pole with a thickness of 155mm on top. The bracket system is available in stainless steel or mild steel and is E-coated and poweder coated against any form of corrosion.

The standard Betta500 configuration will function in most African countries – with more than 4 full sun hours per day - 2 x 80W solar panels, 4 x 22amphr lead crystal batteries, 1 x charging unit, 1 x LED light head, bracket set, 2 x battery boxes, complete wiring harness, 3 days of spare battery capacity available – all fasteners, bolts and nuts required are included.
