Can you straight swap LED for Halogen - IR motion flood

[Vipersan]

Obviously LED lamps are more energy efficient ...but never tried this before so advice needed from someone who has ..
150W exterior IR motion detector Flood lamp ...uses short halogen ..
But these are always failing and energy greedy ..so wondered if I could pay a little more and straight swap the halogen bulb for a LED variety ?
Dont want to have to take down the flood lamp ...so bulb replacement is preferable.
Next question ...
the short halogen I think is either 100 or 150Watt ..so what is the LED equivalent ?

VS

Just free thinking here. You may find that an equivalent LED replacement is not available size for size for the halogen bulb. Obviously there are PIR controlled LED lamp assemblies but I think they are purpose designed.

I'd be happy to be proved wrong though.

There's this kind of thing VS that are supposed to retro fit into an existing 118mm 150watt halogen lamp, they are rated at 9watts. Whether it will physically fit inside your existing fitting ??.
They are around £16, might be less hassle to replace the old one with a 10watt led flood or pir/flood for similar price.

Does the LED replacement use the same voltage as the halogen one? In fact what voltage is the halogen lamp? Probably mains but worth checking.

Yep tis rectified mains usually switched through a Triac by the PIR ...
So I assume you can just retrofit the flood with a 240v Led array ...as it is DC .
I figured they were available but thought it best to ask first.

Los viejos detectores halógenos que tengo de 500W máximo, tienen un relé de 6Amperios que puede controlar fácilmente varios focos de led.
Normalmente tendrá la placa de control IR y detrás la que comento con el relé de control.

Puedes sacar alimentación a 230Vac para unos focos led externos extras o meter uno dentro del foco (los que tengo de 15x11'5cm), el de foco led 10W entra bien (11'2x8'3cm) OK.
De 10W..... 9€.....Ebay: 381442505806
De 20W.....17€
De 30W.....25€
De 50W.....38€
Foco 10W led + PIR = 14€...Ebay: 351554515400

Modificar el foco halógeno para meter led sale mas caro por el tema de la disipación de los led.
Si tienes disipadores gratis lo puedes hacer, de otra forma no merece la pena.
Led de 10W + power....3€.....Ebay: 261740252784
De 20W.....5€
De 30W.....6€
De 50W.....9€
De100W....18€
Recuerda, el disipador es muy muy caro en general.

Los viejos focos en la finca los tengo asi (3x10W led), después del verano actualizare con unos detectores de microondas que pondré en cajas estancas (1-12 metros).
---------------------------
The old detectors 500W halogens have maximum 6Amperios have a relay that can easily control multiple LED bulbs.
Normally have the plate IR control and behind that comment with the control relay.
You can take food to 230VAC for some external LED lights extras or putting one inside the focus (which I have to 15x11'5cm), the focus 10W LED goes well (11'2x8'3cm) OK.
10W ..... 9 € ..... Ebay: 381442505806
20W ..... 17 €
30W ..... 25 €
50W ..... 38 €
Focus 10W led + PIR = 14 € ... Ebay: 351554515400

Change the halogen bulb to put out more expensive led by the issue of dissipation of the LED.
If you have heatsinks free you can do it, otherwise not worth it.
Led 10W + power .... 3 € ..... Ebay: 261740252784

De100W .... 18 €
Remember, the sink is very very expensive in general.

Old light bulbs on the farm so I have them (3x10W LED), after the summer will update with microwave detectors in sealed boxes I will (1-12 meters).

Tema mosquitos y otros bichos segun la temperatura de la luz.
2700K-3000K sin mosquitos, luz calida.
5000K-6000K con mosquios, luz fria.

En el porche todos de luz calida y uno alejado de luz fria, van todos los bichos, tambien las mantis religiosas que se ponen las botas.
En la Sierra de Madrid (1000 metros de altura) tenemos de todo.

Los viejos tubos de ahorro de luz fria/azul (15-20W) con 2 vasos de plastico amarillo dejan de tener / atraer bichos.
Son como los blancos desechables, en la seccion de camping los suelen tener.

Si quieres difuminar la luz de los led (10W led duele), los vasos de 6x7cm son ideales, con una gota de loctite en el borde se pega bien, si no pasa de 50ºC de temperatura los led, duraran años, si sobrepasas esta temperatura, duraran menos al quemar sus 50.000 horas de vida estimada (1 año +/-).
----------------
Topic mosquitoes and other bugs according to the temperature of light.
2700K-3000K without mosquitoes, warm light.
5000K-6000K with mosquios, cold light.

On the porch light all warm and one cold away from light, go all the bugs, also praying mantises put the boots.
In the Sierra de Madrid (1000 meters) we have everything.

Old pipes saving cold / blue light (15-20W) with 2 cups yellow plastic stop having / attract bugs.
They are like disposable white, in the camping section usually have.

If you want to blur the light of the LED (10W led hurts) vessels 6x7cm are ideal, with a drop of loctite on the edge sticks, if does not exceed 50ºC temperature leds, would last years, if you exceed this temperature wil least 50,000 hours burn their estimated life (+/- 1 year).

Loads of them on ebay.
