What is the price diff in running a 70 w metal halide to a 80 w fluorescent tube ?

Hello Daithi,

We mostly deal with customer supply rather than queries as technical as the above. ESB Networks are the people for engineering queries.

Hey Una , they were no help , I can figure out price of fluorescent tube on your calculator just can't find out how much to run a 70w metal halide . If you or anyone could give me an idea that would b great . Cheers , Daithi .

Hi again Daithi,

I am still trying to get a definitive answer on this, and will have it for you ASAP.

As a unit is a kilowatt/hour then surely a 70 watt costs 1/8 less than an 80watt irrespective of what the item is - provided the wattage is constant. Could be off the wall but it's just a thought.

I know what your saying alright but the metal halides are renouned for being heavy on power and the fluorescent tubes ( which are A rated ) are supposed to be fairly efficient , don't know now !

Hi Daithi,

Thanks for your patience.

A 70W metal halide lamp will cost about 11 cent to run, over a 10-hour period if the electricity costs 16 cent per kilowatt hour. So it is roughly 1.12 cent per hour.
If it is a floodlight, a 30W LED lamp would give equivalent light at a running cost of 48 cent per hour. So if running for 10 hours a day, yearly cost for a 70W metal halide is €40.88 euro and yearly cost for 30W LED would be €17.52.

That's exactly what I said. 70 watt is 70 watt. 70 watts of anything for 10 hours is 11 cent. 0.7 kWh x 16 cent = 11.2
