The light output is 1800 lumens and you want to know how bright it is compared to an old halogen torchiere. Lumens to watts calculator it is a conversion calculator that is used to convert the luminous flux in lumens lm to the electric power in watts w. Energy saving lamps have high luminous efficacy more lumens per watt.

Similarly if you want to replace your 53w halogen light bulb with a modern led the led will probably use between 9 and 13 watts of energy. The luminous flux φ v in lumens lm is equal to the power p in watts w times the luminous efficacy η in lumens per watt lm w. Designed to replace fluorescent tube bulbs these led tubes are available in 8 and 16 watts which replace traditional 25 watt and 40 watt t8 t10 t12 fluorescent tubes. It delivers accurate results based on the values entered in the text fields which makes it an effective calculator in performing the conversions.
