I know you can get a floodlight for this sort of money at most places but the are several hundred watts whereas this is only 24 watts so it'll keep your electric bill down with all those false activations lol. The bulb life span should be around around 8,000 hours.



* With motion sensor and twilight sensor
* Adjustable light duration up to (mins.): 12
* Adjustable sensor range up to (m): 12
* Sensor detection angle: 200°
* Includes energy-saving ESL R7s 24W light bulb

Are these easy to install?
What's the power, battery or mains?

it's just that ours doesn't work anymore, so would be nice to get rid of the rusting light and replace it with this one

Good deal as it includes the special bulb

As easy as wiring a plug and drilling a couple of holes in the wall. Yes it uses mains power.

Yep, they are around £8 on their own, but do last a very long time.

Good deal, it will take a bit longer to warm up than a halogen though and will produce a blueish rather than yellow light (I have a 42watt one that is switched rather than PIR).

I belive this 24W energy saving floodlight with R7s lamps provides the equivalent of a 300W halogen lamp - 90% less consumption.

it uses a big version of the energy saving bulds we see in the home.

Im not sure how long it takes to get full brightness though so if it for a alleyway which is short and often peopel may want to consider the tradditional one. Flooding a back yard for the evening this would make £££ sense!

Presumably you can just swap out the energy saving bulb for a halogen version anyway though. I've got an old halogen lamp on the back of our house and the screw holding the bulb compartment shut is rusted solid and the screw-head is worn... I can't even drill the sucker out. This would make a decent replacement, I reckon, but seeing as it'll be on for only 30 seconds at a time or whatever as we dive out the back door to ditch some stuff in the bin, I'm not too bothered about the energy saving aspect!

Thanks for the reply guys. Now I just need to hack off the old one since the screws have rusted away, and use the same wiring for this. Nice

Try drilling the old screws out with a dremel or similar small tool which work well in limited access areas, if you know someone with one, they can prove so handy.

Does that mean the burglars have about 20 minutes before the bulb gets bright enough?...sorry couldn't resist.

I bought a couple of these from our local electrical factor to illuminate our parking and workshop frontage. They were under £10, so I don't think these Lidl ones are especially cheap (although probably cheaper than B&Q etc).
The R7S 24W lamps are OK, but definitely not as bright as a 300W halogen and they are a bit sluggish to warm up. They need a minute or two to reach full brightness. Halogen is definitely better, but obviously uses more energy. If the lamps are to come on only occassionally then stick with halogen.

Good deal. I've been looking for energy saving replacements for my security floodlights for some time now. The LED ones tend to be quite pricey and not that bright, but this looks good.

This makes me wonder if they are any use as a deterrent. If they really do take this long (and I have some ordinary CFLs that are dim for a long time before brightening, so I could well believe it) then anyone skulking around will either have gone past the zone of illumination by the time they'd become noticable, or seen it, been warned and disappeared - which might be just as good. However, having a light coming on when there's no-one "caught" by it means you'd quickly lose any interest in investigating and just assume it was a cat or soemthing.

Looks like a good buy. So could i just replace the bulb with a Halogen bulb only it would be pointless if i had to wait for it to warm up for a few minutes.

Thanks,

Nice environmentally, but defeats the point. Will illuminate gently, slowly revealing good hiding places and places not to stand, without catching anyone off guard, so perfect for thieves..

..if using as a security light, I mean

Mind you, if using to say, illuminate a car port, you're in out anyway.. can't see many scenerios where its useful

How much under £10?

regarding the alleged warm up time. When I get mine I will be wiring it up that morning, I will make a video of it coming on once it's dark to show this warm up time stuff. I really cannot imagine it's that bad at all.

I have no idea whether the two bulbs would have the same fitting, but even if they do, this would be a REALLY BAD IDEA.

Energy efficient bulbs waste less energy than traditional halogens, and that wasted energy is effectively shed as heat. The energy efficient bulb here may be shedding about 15W in heat, which is significant, but not a huge amount. If you swapped that for a 300W halogen, which is MUCH less efficient, then that will probably be shedding 250W+ in heat. That's a lot of heat in a small volume, and unless the fitting is specifically designed to cope with it then it will probably burn..... Just be careful.

btw, aside from the issue of start-up time on the energy efficient bulb you also have to consider premature aging on the bulb if it is switched off and on a lot. Whilst the bulb is probably specied for a very long continuous operation (perhaps 5-10 years) it won't last nearly as long if it is switched on and off frequently. That's because these bulbs use a high level of power/ionisation to start-up, and that strips the phosphor coating from the inside of the bulb (which steadily degrades the light output).

Just some food for thought.

if you do, you must make sure that you fix the cameras exposure and set accordingly otherwise it will look like the thing reaches full brightness straight away.

Anyway, as above the one thing that kills fluorescent lamps is the on / off cycle so as others have said these will be fine for lighting outside at night but IMO not as good as Halogens as a deterrent.
I am thinking about one of these for my garage actually and maybe bypassing the PIR!

Great ,bargain . I'll be getting a couple of these . I was going to buy a special bulp for these security lamps from ebay awhile back for £8 , so these are a good deal . These lamps are handy for putting inside your garage , so when you open the door and drive in the lamp comes on automatically .

As suggested above, these bulbs will last about a tenth of the rated time if repeatedly switched on and off (as will happen in this situation). The amount of electricity used by a normal bulb is negligible if it's only coming on for 5 minutes or so, and the normal bulb will be at full brightness instantly (required here). This is the wrong application for this type of bulb!

Been Looking for one of these Bargain

I had an energy bulb in a lantern style light with a pir, lasted about 5 years. These bulbs are designed for this so I think your talking out ya elbow.

Is it difficult to make this switchable instead of PIR?

Are you saying that low energy bulbs don't react very well to being switched on and off frequently? Our internal ones are always being switched and no probs there.

I would have thought it would be quite easy. It's unlikely to be a sealed unit. Open it up and disconnect the pir from the main lighting wiring and walla.

How much would his cost to run on standby all day and night?

Thanks

As good as nothing, the same as all pir security lights.

Where can I find the more powerful versions for around this price and/or a version like this without the pir?

More powerful? 300 watt one's?

I went to Lidl in Bournemouth and they didn't have any.

If anyone gets a spare, let me know. I'll give you a tenner for it.

Rod, they're out on the 14th as per the thread title, so keep your money in your pocket until then

Unfortunately the winter will not make things any better, the cold weather makes these lamps slower to reach their intended brightness, a great money saver for a light that remains on for some time but not ideally suited to being switched for short periods with a pir, still a great buy though at £7.99
