LED Floodlamps

[Adam]

Hi, has anyone got any experence with the above?

I have a pir sensor at my back door coupled to 3 incandesent outside lights with a combined wattage of around 300w, i would like to replace them with something more efficient.

Thanks ad

Hi Adam - are the lamps the type with the long thin halogen bulb (150W)? If so, the only thing I've found are these compact flourescent bulbs. I'm yet to be convinced that the £9 price tag is worth the energy saving...

well think again pphilpot,the hideous wastage caused by 500watt halogens is criminal.Our company refuses to fit them;but have had good results with a 24 watt l/e similar to the b&q product;and baulking at investing £8?you cheapskate!

[Adam]

Theres no halogens, just 2 bulkheads 1 corner lamp.

500w halogen lamps should be banned on enviromental grounds, anyone that has no knowlege about the efficiency of these lamps buy them because they are so cheap, 2 years ago our neighbour had most of his farm buildings burn down because a bale of hay fell against a 500w lamp .........................Rant over!

My pir unit is a stand alone type (not fixed to a lamp) and was an expensive unit, as most cheap unit's switch on in the slightest breeze often in daylight too .

I have tried cfl's, their ok when warm but they take an age to warm up in cold weather, not really looking for replacement bulbs more like replacing the lamp with somthing like this http://cgi.ebay.co.uk/LED-Floodlight-beamer-light-lamp-ceiling-spotlight-new_W0QQitemZ380078119729QQcmdZViewItem?hash=item380078119729&_trksid=p3286.c0.m14&_trkparms=72%3A1301%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318  or something cheaper.

Short thread here a couple of weeks ago.

We bought the higher and lower power and took the higher power(42W) one back. 26W is fine, in fact we tried to find an even lower wattage bulb to fit (but couldn't)

Oops!.....looks like i've just duplicated a thread

Is your cfl ok with the cold? have you got it wired to the Pir?

I have a old 70w SON sodium floodlamp with knackered balast, have removed the balast & choke and fitted a 26w ES cfl, works great on a time switch and throws loads of light out but it's very dim when cold so no good for pir

Hmmm, the forum is becoming a little tense lately...

...FWIW my halogens are 150W (x2) so £16 for a few minutes on-time here and there is a non starter to me.  Cheapskate? Nahh, just being sensible.

I tend to use normal bulbs as they are never on for more than a few minutes and the CFL is only just getting birght enough by then especially when there's a foot of snow outside.

I have the led flood sold by that seller (but the smaller one) & another, the area immediately outside a door is nicely lit but not like a 500 watter (obviously) however provides ok working or avoiding obstacles light in a fairly restriced area.
I'd personally go for the larger size next time, but frankly get whatever is available cheap at the time.
comes with a 2 pin continental plug so needs an adaptor plug, has an outside of lamp transformer (handy for a cooler lamp) & a water resitant screw connetor.

 very good overall, my sparky friend is having major problems getting hold of them at the wholesalers, so don't expect to see em in the mainstream over here fro another 18 months I reckon

Mr Gus,

I have a 1kW security PIR at the front of the house - I need it for security and also for lighting up our treacherous steps at nighttime. It's only on for 30seconds at a time, so doesn't use massive amounts of power, but I'd gladly swap it for some LED version. Can you please tell me if it provides a wide-angle of illumination like a conventional floodlight, or does it provide a small pool of light?

[Billy]

Depends how they are set up,

the replacement for the vertical filament all round light on boats is to have wide angle leds (high intensity I think), four vertical rows on a tower of four high.

If the array were to be designed right, or one made it to fit into the fitting you have, it would be a very acceptable alternative.  I haven't seen one yet, but the electrionic boys could knock one up in a jiffy I bet.  The dark arts are beyond me  (where's my hammer?).

The only downside is the cost, thirty odd quid to replace a six jobby, but if your techy mates .......  Ultraleds or something, leds on a circuit board.

Hi

something like that one 30 watt as a replaceement for a 300 watt spot should be easy built yourself  (perhaps as a 12 volt solution)

this one uses angles from 6°, 30°, 45°, 110° led

Smallish pool of light Ivan, I did actually (in a previous thread) mention the manufacturer that the german guy on ebay is getting them from, they have quite a few different size models...(about 15 as I recall) ..my main use is as a good loft light & to light up the dogs run etc (avoiding dog bombs)
I'll have a look I'm sure it's in my 200+ favourites
