LED-light and motion detector
If you haven’t already done it, changing your lighting to LED can save you a lot of money in the long run, and it has huge environmental benefits. LED lighting usually last much longer than traditional light-bulbs (up to 60.000 hours) and is significantly more energy effective (90% less energy consumption.) The costs of maintenance is lower and they lighting systems are safer than traditional ones. The initial investment will take you back on the monthly budget, but both your wallet and the environment will thank you in the end.
To install motion detectors in common areas and bathrooms is an effective method to reduce energy consumption and save money as well. We have visited many hostels that have implemented this easy-to-install technology and they have had good experiences with it.
