    12v Mini Downlights Basic Question

    Appreciate the comments on the Quartz lamps. Do have animals (cats), so definitely worth bearing in mind. Not found any transformers/power supplies of any sort yet.........

    GU5.3 12v or 240v - how to identfy

    That appears to be the case. Probably, but that doesn't mnean that they are the only options available. Indeed, and I think I suggested that. You obviously could do that, but you could also just change that one transformer/SMPSU to one that was LED-friendly. Yes, you could do that if/when there...

    Dimplex Opti-Myst fires

    I thought i would share my experience: Purchased a Opti-Myst fireplace back in Dec 2019. Ran for a week or two, noticed the bulbs (and the water tank) get very hot during use! After reading somewhere (may have been on here) they suggested changing the 50W halogen bulbs for 30(35?) watt bulbs...

    Electric lock tripping PSU

    Hi All, I have a 240v Access Control Power Supply which outputs 12VDC / 3A via a built in relay, connected to a 12VDC electric lock (which has two solenoids & a 1n5408 diode in parallel across the terminals) and a 12VDC RFID keypad. I purchased these as a project to help me learn about RFID and...

    Changing from Halogen to LED bulbs

    First of all thank you very much for you help in the past. This problem involves a en-suite shower room in a 16 year old house ... we have only had the house for 2 years. At some point 3 modern flush fitting MR16 halogen lights were fitted and a forth one in the centre of the ventilation fan...

    WIll downlighter bell housing cause fire to insulation above

    Conks - you aren't going to be able to fit these lights, not legally anyway. The work is notifiable (see http://www.diynot.com/wiki/electrics:part-p), and since it is notifiable, there's no way you're going to be able to get Building Regulations contraventions past the BCO. It isn't just...

    GU10 LED lamp on 12V Driver Transformer possibility

    1) Although I am sure you will find 12 volt LED GU10 bulbs they are clearly not as easy to source as GU5.3 bulbs and to use non standard bulbs is asking for problems. 2) Although the pins of a GU5.3 bulb with 50W or 4A seem to fail with 0.8A there is really no problem. 3) The LED low...

    If starting from scratch what lighting would you get?

    What on earth leads you to think it is either? It is a statement. I will make this as simple as I possibly can: The lights you suggest are intended for non-domestic installations. Which part of that do you do you consider is incorrect? The lights you suggest are intended for non-domestic...

    12 volt LED lamps what is the voltage range?

    Thank you "mikely" yes using those drivers clearly will work but "leeco" link is typical GU10 voltage range 85 - 265 volts MR16 just 12 volt. Not tested white LED but know red one has a 1.2 volt drop across it often used to raise the output voltage from a 7812 voltage reg to 13.2 volts. So...

    84 LED Bulbs so Expensive at £350!

    Since the low heat output bulbs hit the market I have found quality and price and make have no relation to each other. I though Philips was a good make and swapped the light fittings to hold more bulbs and got 16 CFL for living and dinning room. These started to die rather quickly so my wife got...

    Quick turnaround EICR certs

    ...says I do seem to remember some thing about access to loft spaces, but it states "carried out without dismantling" and I know many remove MR16 lamps to check if hoods fitted or earths fitted, as to "with partial dismantling" it really does not make sense, to my mind you need to remove the...

    Suppliers 12 volt LED advert and advice.

    With the quartz bulb the filament is thicker at 12 volt than at 230 volt so it takes longer for the thickness to vary enough for it to rupture, also the whole idea is to maintain a constant temperature too hot and it burns out, and too cold and the tungsten is deposited onto the quartz rather...

    GU5.3 12v or 240v - how to identfy

    It has been an interesting read. Personally I only have 4 x GU5.3 12 volt MR16 lamps, all the rest are GU10. They (the 4 GU5.3's) are powered by a single toroidal transformer. In real terms they were a fad and not required, but filling in the holes in ceiling would be a pain. So PoundWorld did...

    Spotlight help

    It would seem the lamps are being changed from 12 volt which yes is extra low voltage and would if separated (SELV) have no earth or functional (FELV) where it could have an earth or protective (PELV) which will have an earth. And supplied from a device which transforms the supply from 230 Vac...

    Lighting a house - ideas please

    The lighting of any room is complex. So think it is as simple of looking up size of room seeing how many lumen is required and fit lamps with that output. However colour in the room and direction of light from the lamp plus spread of light leaving the lamp are all important. At my bed head I...

    If starting from scratch what lighting would you get?

    My apologies - I mistakenly thought that this: was a criticism of me suggesting that lights "intended for non-domestic installations" could be used in a domestic environment, not an agreement. My apologies - I mistakenly thought that it was OK to use them in a domestic environment even if...

    Recessed spotlight spacing

    There is a huge difference between recessed lighting and spot lights. The typical MR16 or equivalent has a angle of light which varies from bulb to bulb including how shape the cut off is. Using a angled spot light aimed at a white wall will light the room far better than one shinning down on a...

    Halogen to LED downlights ??

    I find cost quartz to LED is rather hard as they are not straight like for like. With 12 x 35W = 420W that is a lot of heat, so one would be looking at air conditioning units to remove that heat. Do you include the cost of the AC in the calculations? likely not, but you will likely include the...
