LED PIR floodlights or halogen?

Supercell

I have an existing halogen floodlight on the back of the house which gives great light but doesn't have a PIR
I want to replace it with one that has a PIR for security reasons and convenience.
I see that there are now LED ones with far lower wattage. I was thinking of something like this through parcel motel
Given that the floodlight is rarely on for very long I'm not really concerned about wattage to be honest but more about lumens.
I would imagine that leds last longer than halogens but maybe I'm wrong.
Anyone have any experience with led floods and any caveats with them ? Can I get one with a decent amount of lumens? Thanks.

I have a LED floodlight, and as far as I am aware, the biggest downfall with them is that the entire unit needs to be replaced once the bulb is gone. There are no replacement bulbs, just have to replace the entire thing.

Yeah- but their expected life is huge -

Yep, true, I just wanted to make the point in case this came as a shock to him when it breaks in 2030...

Thanks, if it lasts five years or more that will be acceptable, the current one is rusted to bits anyhow.. I'm leaning towards this 100w led one which hopefully will light up the place well.

I purchased a cheap LED one and it lasted about 4 months up before the LED panel went in it.

I was putting up flood lights for a family member a few weeks ago on a new house they moved into and decided to go for Halogen, one LED flood light from the whole salers was coming in at €75, where as I got fairly decent quality halogen ones for €25 each. Also the wholesaler threw in 2 300W bulbs, as I was worried the 500W would be too much.

It was hard to justify the additional €100 for the LED ones, as they are PIR for the amount of time they are on (1 minute here and there) the additional power will be negligible. I find in general 500W halogens are too bright for most back gardens, you'll get the same from a 300W light and not annoy anybody too much.

I also have 2 spare bulbs now, although there's some PIR halogens I installed 20 years ago still on the original bulb.

Those cheap led flood lights are crap and they let in water easily too,if placed in direct path of rain,best to install a flood light right up under the roof overhang where it has at least some protection from wind and rain ingress.
A better alternative is to remove existing flood light and wire a stand alone robus or steinel pir off that cable,then run a length of 1.5 nymj or artic flex each side and install 2 black plastic bulkhead lights.Fit an LED bulb into each unit and you now have a reliable security light system that gives good light,is reliable,wont rust away,wont let in water and wont use up a lot of power either.

Halogen lamps use very little power when switched via sensor. On average about €1 per bill. The light off a halogen is far better than LED IMHO.

Not trying to be smart,but, it will use the same amount of power when it's on regardless how it's switched. The value of a pir is in not having to remember when to switch it off.
The cost per billing period will still be governed by how long it was on for and that average will vary by how often the pir is activated and the duration of time it's set for.

Do you write vcr manuals for a living?

Cost of running light x how long its on + cost of light. I think we get it. Depends on how you use the light.

€1 = 5 units = 5kwhr = 10 hours (for 500W) or 18 hours for 300w.

Its hard to see how a pir light could be on for 10 hours... So I'd guess the cost is much less than €1

In the end I decided to get a cheaper halogen. The savings of led didnt stack up when as pointed out its not going to be on very much.
