outside lighting

Oct 21, 2015 20 Replies

Hello,



With it getting darker earlier, I'm thinking again about outside lighting. I did ask before about LED floodlights but went off the idea because they seemed too blue in colour.



I remember someone here saying that rather than have a PIR-controlled bright light, it was better to have a dim dawn-to-dusk light. I am thinking about that. I don't want to add to light pollution but I think a dim light sufficient to see where I am treading and to see the keyhole would be enough.



The only problem with that is that I think I would like a brighter light for when I want to do more than see where I am going. Unless I use a dimmer, I would have to have two light fittings. I suppose that would not look excessive, but I was hoping to just use one.



I have seen hi-lo lights that are normally dim and go bright when the PIR is activated but these use incandescent bulbs so I imagine it is expensive to have these on every night from dawn to dusk.



Are CFL or LED hi-los available and are they any good?



My experience with a PIR, light sensor, and lamp all in one unit is that it is always a bit of a compromise.



What material is best for an outside light? Brass would be too expensive and would stainless steel look too industrial? I have had painted aluminium lamps in the past but after a couple of years the aluminium has started to corrode. To be fair these were just cheap lamps from the like of Toolstation; perhaps I should buy a dearer make for more longevity?



I see you can get polycarbonate which would not corrode but does it look too plasticy?



Interestingly most outside lights use ES bulbs. Why is this? I know it would allow international sales of the same model but the same argument would apply to indoor lights, yet they make ES ones for abroad and BC ones for the UK?



Thanks, Stephen.


Now put it on a PIR and eliminate most of the run cost

Hello,

I have an Aldi, painted aluminium, Quartz halogen, 300w floodlight that's been on our back wall for 10 years and its showing no sign of corrosion. My favourites though are the two ex MOD "airfield lights" I have wired via a PIR covering the drive and parking area. Although I only have 32w quartz halogen bulbs in them the reflectors are so good they give as good a light as the 300w flood.

Airfield light.

Does that really much matter for outside lighting?

I've recently replaced 300w halogen outside flood lights as they were falling apart.

Got 30w LEDs from Lidl at approx 25 quid each. Nicely made.

They ain't as bright as the halogen, and 'cooler'. Subjectively, looking out of the window at them when it's dark, I'd say the colour looks like dusk on a cloudy day. So not unpleasant.

Well the OP could fit a warm white LED floodlight if it matters that much.

LED come in various colour temperatures BUT you are fitting it outside and not in your living room. I perceive that my cold white/blueish LED floodlights of 10 and 20W cut through the gloom/mist a lot better than the warmer halogens that I've had in the past.

I'm sure that I've seen the hi/lo type with LEDs. Possibly is one of the CPC glossy pamphlets.

Most LEDs are bolted directly to the metal housing which acts as a heat-sink.

I've not really looked, but is there the same choice for fittings with non replaceable LEDs as with domestic LEDs?

You can certainly get some LED floodlights with different colour temps. A quick glance at a CPC flyer next to suggest some are about 4000K, others about 6000K

Unfortunately not - but they are available. I do not know if it is just marketing or just because people believe that colder coloured LEDs are brighter than the warm colours or a mixture of both.

Generally, they're right. 'Cool' LEDs are - or were - more efficient than warm. If you go back to the early days of LEDs, white was more blue than white. And when warm arrived it was a bilious shade of green.

Believe or perceive? I've tried 3W 320lm lamps at 4100K and 4W 400lm lamps at 2700K in the same fitting in the same room (the lamps have very similar spread) and the 'cooler' ones just seem to be better. The room is 'warm' decoration. Conversely, in a 'cool' room the 'warmer' lamps seem to be better.

You can now see why I do not wish to get rid of my front dusk till dawn operated floodlight for an LED. I always use a Philips MASTERColour 35W CDM-T lamp in it (not sold in Poundland).

The lamp need replacing every two years - it still works but I can see that the output it is not as good as it used to be.

The back and side of house lighting will get replaced for LEDs the next time their CFLs fail (both are also dusk till dawn).

Wouldn't that be the other way around? After all fog lights are red to go through fog rather than blue?

Thanks. I did not want to use filament bulbs for this reason. If a hilo cfl existed, I would try that. I was hoping that being on from dusk till dawn should give it time to warm up and avoid any of the problems caused by cfls in cold temperatures.

I presume just as dimmable cfls need special dimmers, you can't just put a cfl bulb into a hilo light sold for filament bulbs?

Thanks, Stephen.

That's not so bad then. I was afraid they would be very blue.

The fixtures designed for LEDs tend to have proper heatsinking and bespoke built in LED arrays bonded to it. Seem to be available in warm white, blue white and these days colour changing varieties.

I was thinking more about filament/cfl/led builbs in traditional design: GLS?

The 30 watt LED floods I got from Lidl have a separate power supply inside the connection box. Similar to a ballast for a florry or whatever.

Much more sanitary way of doing things than building it in to the bulb.

Not really. Other comparison might be moonlight. But rather brighter. So OK to me.
