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,

    The answer is that it cant! A rough guide is that LEDS are about 8 times as efficient as halogen, so you need something like 40W LEDs. Halogens give around 10 lm/ Watt so the 5000-6000 claim is also far too high. The colour is also different so perceived brightness is better for the LEDS. I suggest you get a 40 or 50W LED fitting and show the customer the difference (safer that way!). You need to emphasise that the LED life is much better than linear halogen lamps so save money in the long run.
