I want to replace the 500watt floodlight on my forecourt as the PIR has lost sensitivity and only activates when you are about 10 foot away despite me fiddling with the positioning.

I see on Screwfix that they are LED now but I am not sure what I need to get to replace like with like to get the equivalent 500watt luminescence?

Many thanks

DWD

10w is about 80w
20=160
30=240
50=400

If I said get this one, and you thought it was "not good" then you would blame me for a poor suggestion, colour temperature has a lot to do with what you seek too. ie a warm white will look more like the flood light you had but a cool white may be brighter.

Personally I don't like one big light i prefer to have at least 2 smaller ones, as you can place them better, and if (when) one fails you still have the other one.

As an aside, the 500w is how much energy the lamp uses, not a measure of its brightness, that is measured in LUX

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

yes i prefer 2 or 3 then with separate switches you have several light combinations with say a 10 a 30w and a 50w
at 3 locations then with combinations have 10/30/40/50/60/80/90w

I have had a 50W LED floodlight outside for about a year, its very bright :shock: and as said its a white light, it illuminates an area of about 30/40 Mt and thats with what I would call a bright light, its mounted on an upstairs window cill :? For the new house I will be using two smaller ones 30W as my land is larger. The first one did have a electrical failure after about three months, I bought from "Amazon" so a refund/ replacement was quickly offered, so I picked a different manufacturer, to be honest they are all made in China so I think it pot luck in your selection.

Thanks chaps, I see now I need to look for a mid range, say 20 or 30 watt. It really is just to click on and illuminate my drive on entry as it is pitch black at night where we live. Also it it is for security so the PIR needs to be more sensitive than how my existing lamp is and pick up movement a bit further away. The brightness and power of the light is not so important so the lower watt range might suffice. I want to stick with one light as my electrical skills are naff and I should be able to swap over a similar to similar connection (I hope)

Thanks all

DWD

Hmm, I just have seen a YouTube video of a 20w light and it seems a bit weak. I think I will go for a 50w one instead.

Bear in mind that what you are watching is what a camera sees that you are looking at on a monitor, not the actual thing.

I have faith in you, that you can add another light.
