5Pack Philips Halogen 12V MR16 50W GU5.3 36D 4000Hrs Dimmable Halogen Dichroic 58845100

Just what I needed to replace failed bulbs and they arrived so quickly after ordering and at a great price. Now we are illuminated brightly in what was a dark place.

Fitted a few in the years since bought and they are great. I've had some problems with these downlighters over the years, but it turns out it's not the bulbs blowing (after I've replaced quite a few erroneously) It's the actual fitting in the light where the 2 prongs go into the electrical hole on the fitting. These are poor quality in terms of the making the contact, but by moving the bulb it will often make contact. So the bulbs are fine but I have to replace my downlighters now.

I bought these bulbs my ceiling spotlights. The fixtures are officially rated 50W, but they end up overheating and the bulb burns out in a month or two.

Just what I needed

Halogen spotlights are becoming increasingly difficult to get hold of. I Saw these items (Good named brand) which I really needed but was struggling to source them from anywhere. Bought five at a very reasonable price so now have a couple of spares until I can find time and the extra money to convert to LEDs.

Did the job for bulbs that had gone out in the bathroom.

The lights work for a long time. I use them for hall and lounge lighting.

Longevity depends on how many times you use the switch, fluctuation of current, how good your transformers are, and so on. The rating should not be there. You need to rate this after a few months years and check if the expectancy life of the product has been achieved. Mission impossibly. - I won't count the hours! Energy efficiency - is rated a B, A is the best, so I scored a 3 It was a good value for money.
