Led Solar Light

You might think we must utilize solar street lamps everywhere. When the power use of street lamps is 60 Watt, it requires 150 – 170 Watt solar power and 2 units 80 Ah batteries. In case the power consumption is higher, like 150 Watt, the cost will be somewhat amazing. As conventional HPS street lights, the power consumption is typically 60W, 80W, 150W, 250W or 400W. Thus, the cost is saturated in most of cases. In the past 2 years, Light-emitting diode street lights become increasingly more popular they are available at very of power eg. 30w, 40w, 50w, 60w, 80w, 100w, 120w, 150w, 180w, 200w. Comparing with conventional HPS lamps, Light-emitting diode lamps can save 50%-70% energy.

Higher power efficacy – LED street lights exceed mercury vapor’s 31 lm/w. You’ll find higher effectiveness dimension from for high pressure sodium lamps. It is simply misleading because contains wasted light that in turn wastes energy. In the market, many power efficacy of LED street lights can reach up to 80lm/w. More Lux Per Watt – over double that of the mercury vapor street light. The equivalent dimension for high pressure sodium lamps is skewed by hot spots that bump up the lux rating, but cause unwanted visibility, safety and glare issues. Since Light-emitting diode lamps are energy saving, it may reduce cost of solar kits. When the cost is low, several nations can accept them. 60W solar Light-emitting diode street lamps can replace conventional 150W HPS street lamps. If you calculate Return on investment, you’ll find it is over 30% in 2 years.
