This one has even really durchrechnen itself:
. In offices and shops lighting between 40% and 60% of electricity costs caused
With the new LED lighting technology itself could be the power consumption – and thus also reduce the Außstoß the greenhouse gas CO2 significantly. These keep the LED lamps significantly longer, do not emit UV light and contain no lead or mercury. The höreren cost
amortized depending on daily duty in a short time.
At 24 hours of continuous operation and 20 cents / kWh, a METOLIGHT LED bulb would be amortized in 150 cm after 8 months.
How to get it now?
The following statement can always understand themselves:
We compare a 58-watt (150 cm) fluorescent lamp with a 22 watt LED bulb. (Both bring similar bright light)
If the fluorescent bulb still operated with starter, then is also a ballast to limit the current connected. This consumes about 20-25 watts of power, which is converted into heat. Thus, the 58-watt fluorescent tube consumes more than 80 watts in continuous operation.
80 Watts x 365 (days) x 24 (h) x 0.20 (€ / kWh)=140,00 EUR Electricity costs / year (700 kWh!)
In contrast, we expect the LED tube with 22 watts (+1 Watt for internal driver):
23 Watt x 365 (days) x 24 (h) x 0.20 (€ / kWh)=40,30 Euro electricity costs / year so 100 euros less!
Now burn in the rarest cases, the lamps 24 hours 365 days.
Realistically for company but are 10 hours in 280 working days. This results in:
for fluorescent tube: 224 kWh / year, ie 44,80 Euro electricity costs
for the LED tube: 64.4 kWh / year, also12,90 Euro electricity costs, a savings of 70% or 31,90 Eur per LED tube
order is the payback period at 18 months
LED tubes of ASMETEC have an average lifespan of about 50,000 hours (about 17 years at 10 hours / 280 days). The light does not flicker and much more pleasant than that of fluorescent tubes.
