halogen replacement with led

[petulia]

Hi,
I have a eldiss 115 2015, the halogen bulb, which is from the small spotlight under the cupboards in the bedroom area, manual says they are 12v mr11 bulbs 1.2w, I have just purchased the exact equivelent in a Led but, it is about 5 times the light less that I had with the halogen. Not sure if any one has the model/year and have replaced the bulbs, as these ones I have purchased are not bright enough, so something is not right.
If any one could help on this subject, I would like to hear any advice.
Electrics are not something i have had much experience in hence the question of help
Many thanks

What W did you have ? What W have you now got ?

35w is the normal max in MR11 and these should do the job as a quality item.

Seems very low wattage for a halogen, 10w is more the norm. Is there a value printed on the original bulb or check another one. There are plenty of MR11 LED lights that should give you the equivilent light output with less current. Generally halogen was rated at 25 lumens per watt, so a 10 watt lamp would be around 250 lumens. That being the sort of figure I would expect for a lamp of that type. Halogens are no longer available .

Hi,
thanks for advice, the originals clearly have been in a long time, we have just purchased the MH, there was no wording anywhere on the original bulbs, I have just gone from the manual I have, will look in to these options and see if they work ok, i expect I have halogen transformers, so I am hoping they will be ok, fitting led in to them, many thanks

thanks for information, will look at getting the led's for the new bulbs, as I said to one of the other members, I expect I have halogen transformers, so hopefully will be able to put in the led bulbs without any problems ?

Look at Aten lighting they are good

have you swopped polarity

Try turning the lamp round in the holder through 180 degrees. They are supposed to detect reverse polarity and switch, but we had three that gave an extremely poor light output. I turned them round so positive was on the correct pin and they have been fine since. As mitzimad highlights, LED's are polarity dependent.

I have the same lighting set-up in my Elddis and replaced them with these MR11 12v LED 9 LEDs 11-18v AC DC replace 10w - 20w Halogen

I think what you mean by a halogen transformer is one of those transformer bricks that changes 240V AC mains in a house into 12V DC that a typical halogen bulb will run from. If that's what you mean, then you should be aware that they are not used or required in the habitation section of a motorhome, because the power source is already 12V DC from the battery. Probably the halogen bulbs are connected directly to the 12V battery - through a fuse and switch, of course.

LED bulbs produce about 8 times more light for the same watts power consumption, compared to halogen bulbs. A halogen bulb wastes a lot of power as useless heat. So an LED uses about 8 times less power, and runs cooler too, as a bonus.

The link in Landy Andy's post is for a 4W LED bulb, equivalent in light output to a 35W halogen bulb. It lists the actual light output in Lumens as 345 lumens, quite bright I think.

The other thing to consider is the 'colour temperature'. As something heats up and starts glowing, it goes from red, orange, yellow, orangey-white, white, cool bluish-white. LEDs can imitate this - a colour temperature of 2700K to 3000K is 'warm white', equivalent to a halogen bulb. You can get 'cool white' or 'cold white', at a higher colour temperature, which many people don't like for a living area but like in a kitchen or utility room.
