Lumen equivalents of halogen floods v Led

hertzal123
I am trying to find a replacement for 300W halogen floods.A search online gives halogen 300w as 5000/6000Lm.Looking at a Luceco  led flood in electrifix

catalogue,it claims 22W is equivalent to 300W halogen,but they only give 1800 Lm,so how can they be as bright as the 300W halogen?

Thanks for any help.

                                    Regards,

    I don't know how much a halogen lamp output deteriorates with life.

     


    In some cases 100% every five minutes! ?

    I've been replacing fluorescent lamps with LEDs in several buildings. Going on manufacturers so-called lumen figures I'm either going to be suffering from burnt retinas or groping around in the half light! In practice I've just gone ahead and swapped them over and generally been satisfied. For example we've recently changed a community hall over from 14 70W twin HF fluoros to 14 single 6ft 4000k LEDs. On paper the fluoros should be about 13k lumens total per fitting, the LEDs about 7k so I'd be thinking the light levels will be reduced. In practice the lighting levels in the hall appear to be the same. I did consider going for cooler temp LEDs such as 3000k to replicate the fluoro lighting but 4000k seems perfectly okay without the blueness you get with higher temps.

    One downside I have found with LEDs is the propensity of the drivers to fail, certainly more frequently than the fluoro fittings.
