Low Voltage LED Lamps vs GU10 LED lamps

June 3, 2010   
12v-vs-gu10

Why use Low Voltage rather than GU10?

This is a bit of a thorny issue as there’s plenty of misinformation out there. To cut through the fog you need to understand a little of how an L.E.D light works. Basically almost all LED’s work at around 12v which means that a GU10 type lamp needs to have a transformer (240v

Hi Marcus,

Please follow this link: http://www.yourwelcome.co.uk/led-bulbs-uk/mr16-mr11-led-bulbs/maxilux-zenigata-4.5w-mr16
These lamps are very adaptable to fitting and replacing existing lamps directly, an extra wide beam angle and a nice white light perfect for bathrooms and kitchens.
Just replace your existing lamps with these, they are a retro fit and come with a 3 year guarantee.

I have changed my 12V GU10 halogen with GU10 LED and they seem to be working fine. My question is how do you know the polarity of the LED when replacing the bulbs as LED work on DC whereas halogens filament work on both. Also can I use a Radio Spares 12V 3A transformer to run two GU10 LED bulbs.
Thanks

Hi,

The polarity on LED lamps is sorted out with the electronice circuit within the lamp itself so there is no user polarity to check. You can try the 3A driver, it may work, you need a constant current unit rated for LED lamps as the current is very low, you may experience flashing or no light at all with this driver.

Hi Brian,
Thank you for your enquiry. Are you considering LED Lamps for your bathroom? We have a good range at http://www.yourwelcome.co.uk these will save you up to 90% of your energy compared to equivalent halogen lamps. You can install mains GU10 LED lamps, no need for transformers, just ensure the metal fitting is earthed. You can install shower rated fittings, which have a safety glass in the bezel, these are necessary in Zone 1 and 2 areas, above the shower or bath and if you can touch them whilst in either, depends how high the ceiling is. Cool white colour temperature lamps work better in bathrooms as they appear brighter and are usually higher in Lumen output than warm white. 1 fitting per square metre is a good guide to coverage, unless you already have cut outs in the ceiling or it is vaulted etc..
If you have any other questions you can email me directly on mitch@yourwelcome.co.uk, anytime.

Hi Dean, Yes there is a good choice at http://www.yourwelcome.co.uk look under the LED Bulbs UK category and GU10 LED Bulbs, these are all for the mains 230v ac.
