LED Exterior Flood lights with PIR motion detectors

Andy From Sligo

What the score on these poor LED 'floodlights' that are supposed to replace the 400w halogen floodlights?

I mean like the 400w halogen filament ones gave out something like 8000 lumens of light that cut through the dark in the yard , but I have yet to find a LED equivalent to mimic that amount of brightness . take this one just for example here:

3000lumen output - pretty crap , whats the point in bringing out something to replace something when it performs poorer than the thing you are replacing …. all in the name of economy or modern technology or whatever it is.

So what would you have to be looking at in LED fitting like this to give out the same lumens as the 400w halogen PIR lights they used to sell? - do they even sell a LED floodlight with a 8000lm output? - i bet if they do they are not as cheap as 10 or €15 euro as you used to be able to get 400w halogen lights with a built in PIR motion sensor.

Out of curiosity is it fully charged as i have 2 other that work on solar panel but in winter they fail as not enough sun. Brighter in summer or is your mains powered.

No, this is a 20euro one Screwfix is selling, came into my email inbox . Its electrical (corded) operated no solar. it just says 3000lm.

I got a 10w LED one once (not from screwfix) and it was not a patch brightness wise on the 400w halogen filament floodlight I took down , so I put the 400w halogen one back up and just bought a 400w new halogen tube for it.

the cheap LED ones around 20eur have terrible low Lm brightness - there are ones claim to be at around 9000lm but they are around the 70euro price , not only that the 400w filament ones are warm white 2700k kelvin and these new LED ones are colour rendering of 6000k cool white or daylight or bluish white light …. thats no replacement for a warm white 400w halogen light.

Yes Halogen are bright and warm and spin your esb meter.

ah not for the few seconds or a minute the PIR Motion detector turns it on for - granted if 400w Halogen left on permantly it would more than likely eat into your electric bill.
My kettle for making a cuppa is 3000w, but its OK because its not on permanently.

Mine went faulty and would not switch off ,had to remove power to it to make it go off but got many years out of it.
