Rated 4 out of 5 by from Halogen straight replacement Took a punt on these to replace original halogens that generate loads of heat and eventually degrade the wiring and lamp fittings (and are pricey to run wouldn’t have been my first choice but they were pre installed in the house we bought!) can report that without changing the transformer they are compatible with the fitting and all 4 dim with existing switch (although not with as much range as the halogens) there were 5 in the box which is good value compared to others I looked at which means I can buy another box of 5 and with the spare can replace the remaining 6 halogens in our dining are cannot comment on long term reliability as I have just installed them but looking OK so far!

Rated 4 out of 5 by from Early days but seem good bulbs Hard to gauge reliability on a new purchase, but all bulbs tested seemed to work (and dim convincingly) which was a good start and not to be assumed these days sadly. Fitted easily to replace halogen MR16/GU5.3 downlighters. Run fairly hot, but I understand that is typical even of LEDs, since their efficiency is still not brilliant, but that's a technological limitation. Just something to be aware of if cramming into ceiling cavities.

Rated 4 out of 5 by from Very good halogen replacement Have just moved into a house that had Halogen everywhere and am working my way through replacing these with LED. These are are great replacement with an even spread of light and seem great value for money so far

Rated 1 out of 5 by from Flickering Issues Unfortunately these did not work well for me. I bought a few packs as I needed to replace all the halogens in my flat and these were the cheapest MR16 LEDs I could find (mistake #1). After installing a few of them I realised some of them flickered. I thought maybe it was a voltage issues so I bought a much better quality Osram as a test and no flickering at all.

Are these 12v or mains voltage

A number of reviews indicate these are 12v but I don't see that in the product details. Looking for confirmation.
Asked by: Exos
Hello, Thank you for your enquiry. To clarify these will require a transformer. Hope that helps. Thank you for using Q&A.

Do I need a different transformer as I have standard Mr16 bulbs and looking to upgrade to led or will au-60 transformer suffice already installed

Asked by: murf71
Hello murf71, If you have halogens and are looking to upgrade to LED's then yes, you will need to change your transformers. Thank you for using Q&A

Do you sell a corresponding transformer to use the dimmer feature (on LED MR16) without flickering.

I have tried these LED bulbs (have Screwfix LED dimmer switches) on a number of fittings around my property, but they all flicker. Please provide an answer specific to allow for the dimmer function. Thanks
Asked by: Rick97
Hi Rick97, In order to achieve flicker-free dimming, apart from selecting a suitable dimmer, you also require a dimmable LED driver. Unfortunately the LED drivers that we currently stock are both non-dimmable (Product Codes 4338T and 2107T). Thanks for using Screwfix Q&A. JT

which dimmer switch would be suitable to stop low light strobing?

Asked by: azazazazazazanvmrtcbch
Hello, Thank you for using Q&A. If you type 'Dimmer' in the search bar on our website and then scroll down the page you will see one of the filters down the left hand side is entitled 'Suitable for LED'. However, if you are in any doubt for your particular needs we always recommend speaking with a suitably qualified tradesperson. Hope that helps. MH

This bulb is described as 345 lumens and '35W equivalent wattage'. The equivalent GU10 bulb (4898V) is also 345 lumens but '50W equivalent wattage'. How can this be the case? I assume 'equivalent wattage' is a measure of how bright a bulb is, as is lumens

Comparing LAP GU5.3 MR16 LED LIGHT BULB 345LM 4.6W 5 PACK (6557V and LAP GU10 LED LIGHT BULB 345LM 5W 5 PACK (4898V).

MR16 12v bulbs are brighter and cooler in colour than GU10 240v bulbs for a given wattage. These bulbs are equivalent to an mr16 35w which would be almost as bright as a gu10 50W.
