AGOTD MR16 GU5.3 12V LED Bulbs 7 W, 50 Watts Halogen Equiv, GU 5.3 Fittings, Aluminum Casing, Energy Saving, High Compatiblity,Brightness, 560LM, 38°Deg,Warm White 2700K, Pack of 6 [Energy Class A+]

Used these LED lights to replace traditional halogen bulbs in our kitchen. The bulbs being replaced were a mixture of 20W, 35W and 50W. The LED bulbs are easily as bright as the 50W bulbs and cast a very refreshing cool light around the kitchen. They are definitely 'brighter' (cooler) than the bulbs they replaced. For a kitchen, that works well. You might want the warm white ones for a living room. They feel like they are well built and have a pleasingly solid metal body.I had to change my transformers to use these bulbs. The previous transformers (also called 'drivers' online) were rated to around 60W (they were designed for halogen bulbs). When I attempted to use the old transformers with these LED bulbs, they flickered horribly. This is not a fault of the bulb - the manufacturers are very clear that they may not be compatible with regular halogen transformers. I am now using transformers designed for LED bulbs made by LED Hive rated at 12W ( NEW! LED Driver Transformer 240V - 12V with Terminal Blocks, 0.5 to 12W / 240v AC to 12v DC-AC / ZERO Interference with Dab and Wifi ). They work perfectly. It's quite easy to change them over, though do remember to shut off the lighting mains circuit before you try it!! You may also want to buy new light fittings (the bit the bulb sits in) - I found that our old ones were a bit grubby and burnt/broken in some cases. These are also available cheaply:  (6-Pack) MR16 Lamp Socket, 16CM Connector Adapter New MR16 GU5.3 Ceramic LED/CFL/Halogen Lamp Female Base Socket

These were a bit of a gamble as not so cheap and I have bought quite a few really rubbish LED spots. However, these are really smart-looking, quality construction and clean and bright. A perfect substitute for the lamented, old-type banned halogen ones. In fact you can't tell the difference as the focus is sharp and the strong brightness and slightly warm colour is the same. Had them for a couple of months now and they are all working fine. Recommended.

Don't want to overly punish this product and seller... but I had return them because the light was too "cold" in terms of colour temperature. My 3 year old actually said "we have blue lights!". The beam is also extremely narrow. 4 of these went into my halway and it made it look like an enterance to a night club! All dark around with just a super narrow spot light beaming down.The description clearly states these are cool white and 38 degree beam but I was surprised to the extend of both parameters I ended up buying the Philips ones which are warm white and have a 36 degree beam but apparently much much wider than these (https://www.amazon.co.uk/gp/product/B01KI4E5PS/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1)5-stars for the seller which took the product back and refunded me without hassle.

I ordered these on expedited delivery. They were delivered on time but I didn't realise my electrician was on holiday over the Christmas period. He came today to change them from another make which was giving very poor lighting. What a difference! When my electrician unpacked them he said they were very good quality. The lights give a brilliant light, no shadows and flickering like the last lot! I have no hesitation in recommending these, in fact I am going to order more and change the ones I have in another room, which are giving poor shadowy light. let there be light! wonderful product and so far, the service as equalled the product.

These work perfectly with my existing transformers with no flickering or noise. They're very bright, and I'm glad I chose 'warm white' as even so the light is whiter than the halogens they replace. Anything 'cooler' would have been too white for me. The ribbing design of the outside made them a bit fiddly to get into the spring holders on the fittings as the ribs kept catching the ends of the clip, but with a bit of patience they fitted securely. Only just installed, so no information on how long they'll last, but so far very happy.

Pretty good overall. They don't have quite such nice accurate colour (RI) as some more expensiv emodels, and they don't like dimmers designed for halogens. However they do work with my non-dimmable halogen transformers and they are flicker free. Considering the price these are pretty good. If you want better you have to pay quite a bit more.

I switched from 12v halogens to these using the Lemonbest Wire Connector Socket For Mr16 Mr11 G4 Halogen Led Light Lamp Bulb Holder Base Plug Converter Pack Of 10 and LED Driver Transformer 240V - 12V with Terminal Blocks, 0.5 to 12W / 240v AC to 12v DC-AC / ZERO Interference with Dab and Wifi. All in all in took maybe an hour to convert 5 lights, and it was a simple job. The light is a bright white and there is a slight delay when flicking the switch, but I am very happy with the overall result.

These were purchased as a direct replacement for halogen bulbs in a bathroom. They fitted in the existing holders and operated flicker-free without a change in transformer. The brightness is similar to the previous halogen bulbs with a slightly 'warmer' colour. They have been operating for approximately two months without problems.The bulbs were packaged robustly and delivered rapidly.
