Potential PIR woes
Having bought 4 CFL lights, I found them unsuitable for security lighting, since they take so long to warm up. The value of security lighting is to startle whoever it is. And if I need it myself, the chances are it is too late once it has warmed up. But this would be a good light for leaving on.

I replaced them with the best quality 500w lights I could find; and because they are only on for a couple of minutes at a time don't use much electricity.

BUT, my other problem is that the lights are placed too high (6m up), which makes the PIRs cover too wide an area, and they get set off I assume by bats, birds and who knows what else that I can't see. And don't get me started on the pluming from our boiler.

Also, because they are too high, and can't be angled far enough down, they annoy the neighbours.

So the morals of the story are:

1. Never use CFLs with PIRs (so don't get the Smartflood with PIR).
2. Site PIR units out of reach, but not too high.
3. Make sure that the light units can be angled down adequately.

Thanks for the feedback, Chris. I’ve not had quite the same experience, myself, though. I don’t use my PIR lights to startle intruders. They’re primarily used to light the area well, rather than surprise people by coming on suddenly, so I’ve found the combination of PIR and compact fluorescents works well for me. Different strokes, I suppose.

As to the Smartflood PIR combination, if the ‘startle’ effect is not the primary concern, then I’d definitely have to disagree with you ;). I’ve a farmer friend who has these around his cattle sheds and he absolutely swears by them.

For PIR siting I’d entirely agree. For most homes a combination light PIR is good and very convenient to fit. But where you’re trying to light a big area, then siting such a unit high can certainly be a problem, and I’d recommend having separate lights and PIR, with the PIR trigger sited lower down, and well designed tiltable lighting set high - this would be the best combination. This might mean getting an electrician in rather than DIY, but it would in the long run prove the bets bet.

Thanks for the useful feedback, and hope you’ve found the site useful.

Portico + steps light
We live in flats in a large, converted Victorian house with a columned portico at upper ground floor level, reached by a flight of steps from the street. Can one install lighting in the portico ceiling that would reach down the steps, with perhaps a separate PIR fixture? We were previously blinded, at street level and up the steps, by an 'orthodox' security light+PIR.

outdoor lighting
Would the Eyelid light be OK used in a covered outside porch, as an over head light? We only have power in a ceiling position and finding it difficult to locate a light to suit overhead, to light as we approach door and look better than the existing ugly dead insect collection vessel there at mo.

The Eyelid probably wouldn't suit this location. The PIR detector is very small and I've found that in enclosed areas it doesn't work as well as I'd like. I'd suggest that you have a look at this one instead . . .

I've recently fitted one for my wife's workshop and have been very happy with it, and the PIR detector is very good.

Great Site
I got my lights from e-tradecounter.co.uk. Really cheap and so easy to fit.

I really love reading up and keeping my house green, and If you’re looking for lights you get them from there. Only heard good things about them.

Good luck people!

Thanks Alister. It's always good to hear about another good supplier. Their eyelid lights look pretty good . .

security lighting
Great website - good info!

"I'm not personally a fan of dusk-to-dawn lights, as it seems a shame to have lighting when it's not actually needed."

On a police advice website it suggests that, at night, constant low-level light is better for crime deterrence. The site claims that by the time the PIR lamp triggers, the burglar is already committed to the task....

I'm planning to use photocell, low energy luminaires to keep the visible, but dark, areas of our home lit overnight when we're away. The cheapo PIR units will then be switched off.

Confusingly, there are contradicting reports of all-night lighting having either no impact on reducing crime, or actually increasing it.

See the 'Campaign for Dark Skies' site for more info about Lighting and Crime:

Good luck with your lighting, though, and glad you found my site helpful.

Solar-powered security light
I am currently looking for a security lamp and have found this model on-line and was wondering if you knew of it or had any thoughts? It is a solar light using leds which is very good for cost efficiency which is what I am looking for.

Here is the model: SF03 Solar 'Enforcer' Security Floodlight With PIR Detector at solarilluminations.co.uk

Solar powered lights are, in principle, a good idea, as they use renewable power and don't require complex wiring to set up. In addition, because LEDs aren't as bright as conventional bulbs, they don't repeat the mistake made by halogen security lights which are simply far too bright for average domestic use. Instead they provide just as much light as you really need without blinding everyone who lives nearby.

As to this model, it appears as though the light unit itself is not a very good cut-off. That is, if the light is aimed badly much of the light will simply be wasted into the sky. However, if you are careful to aim it downwards then it looks like it'll do the job for you.

If you're trying to light a big area, though, you may be better with 2 or three smaller solar powered lights dotted around the area you want lit. That way all lights can be kept pointed down and you'll still get good lighting. A model I've been looking at recently and hope to review shortly is the Solar Powered Courtesy Light

A friend of mine has bought several of these to put along his home, and seems happy with them. They're not over-bright, and they only switch on when needed. Worth a look.
