BATTERY CAPACITY
24v DC systems use two 12v sealed lead acid, AGM or GEL type rechargeable batteries.
Battery capacity is subject to the specification of the system.
Battery capacity is from 100 Amp/Hr to 120 Amp/Hr. each battery.
552 SMD/LED lamp with 140w solar panel is supplied with two 12v 100 Amp/Hr batteries.
552 SMD/LED lamp with 180w solar panel is supplied with two 12v 100 Amp/Hr batteries.
720 SMD/LED lamp with 180w solar panel is supplied with two 12v 120 Amp/Hr batteries.
Battery dimensions vary subject to battery capacity. Battery weight will vary subject to battery capacity.
Typical battery life is approximately 3-5 years subject to environmental factors.
Please note, if you do not install or use this product for several months the battery may discharge naturally on its own. By allowing a battery to deep discharge it may cause irreversible damage as the battery may then lose the ability to recharge or hold a full charge. Periodic charging is always recommended when a product is not being used or when the solar panel is disconnected.
For large quantity orders we offer customization of this product therefore some specifications can be changed to meet the specific requirements of a customer.
Alternative battery types, capacities and sizes may be available upon request.

SOLAR PANEL
Highly efficient polycrystalline solar panel.
Aluminum frame with anti-aging and encapsulated.
Low reflecting tempered glass.
Wattage of solar panel is subject to the specification of the system and the solar panel wattage has no effect on the illumination output of the lamp.
Wattage available from 140w to 180w and up to 290w by special order.
Standard stocked panels are 140w and 180w.
If a solar panel choice is offered select a higher wattage panel for northern geographic locations or where optimum performance is essential.
The 140w solar panel is rated at 34v / 4.2A. The 180w solar panel is rated at 34v / 5.3A.
Solar panels are typically supplied in a dual format (2 x 70w = 140w or 2 x 90w = 180w).
70w solar panel dimensions are approx. 26.5" x 36.5" x 2" (LxWxD).
140w solar panel dimensions are approx. 45" x 40" x 2" (LxWxD).
Typical solar panel life is approximately 20-25 years subject to environmental factors.
The geographic location of the street light may affect the size/wattage of the solar panel required.
The amount of SMD/LED's within the lamp head will affect the size/wattage of the solar panel required.
For large quantity orders we offer customization of this product therefore some specifications can be changed to meet the specific requirements of a customer.
Alternative solar panel types, wattages and sizes may be available upon request.

LAMP UNIT (LIGHT HEAD)
Fitted with 552 Cree® SMD/LED's or 720 Cree® SMD/LED's (subject to desired specifications).
All SMD/LED's are white at approx 6000k color temperature. Amber or white/amber or other LED color temperatures possible, via special order only and at extra cost.
Each LED has a light output of greater than 8000 mcd and approx. 6 Lux (Lumens per square metre).
Each LED is rated at 3v dc and 15mA.
Each SMD has a light output of 8 Lumens and a wider light spread.
Using a 20' (6 metre) pole, average light pattern will provide approximately 40 Lux (Lumens per square metre) or 3.7 fc/ftc.
Using a 26' (8 metre) pole, average light pattern will provide approximately 30 Lux (Lumens per square metre) or 2.7 fc/ftc.
