VINSUN® MR16 LED bulbs 3W - 25W halogen bulbs - warm white - 250lm, MR16/ GU5.3 LED, 12V - Pack of 4 [Energy Class G]

Good warm light to replace my 20w halogens. Did work ok on my legacy magnetic 12V AC transformer (which gave 12.5V when loaded with the LED spots), but I bought a 12V DC LED driver for less than £5 to get maximum efficiency and reduce the risk of voltage spikes shortening life. Great value and working as expected.

Bought to replace halogen, working ok so far, no issues to date. Runs/emits less heat than halogen bulbs as expected.

These are fabulous bulbs. I bought these bulbs for a display cabinet in our lounge. The halogen beam angle always gave dark patches. The beam angle on these is perfect; it is 110 degrees and the difference is unbelievable. There is a big BUT though; the write up is not the full story for changing to these cost saving bulbs. You will need to change your transformer to a driver/transformer. This eliminates any flickering. Once you have done this they then give you the wonderful LED light you want and the cost saving they promise.

The lights mostly worked, but made a buzzing noise and, some blinked when powered.

I bought these to save a bit on energy replacing some 20W halogen bulbs. They weren't cheap, but at least I felt I was doing something to help the planet, and save some money in the process.They fit nicely into the fittings with no problem and provide a comparable amount of light to the halogen bulbs they replaced, with a similar warm colour. All good so far.A couple of years ago one of them started flashing intermittently, and it eventually died completely. Now another has died completely.This is dissappointing because I thought these were supposed to be long lasting. They may well be long lasting (6 years) compared to regular light bulbs, but the Halogen bulbs that I still have installed went in well before these and are still going strong (9 years). So compared to halogen they are not long lasting.So - beware. They may be energy saving, but may not be particularly money saving. Now I need to get two replacement bulbs and I am honestly considering going back to halogen bulbs. So I feel I can't recommend these I'm afraid.

They impressed with the bulbs. We have replaced 25 bulbs at 20w each for these 3W leds. We are looking forward to lower energy bill as a result.The bulbs are slightly dimmer but not an issue at all. 10 of the bulbs are used 60 hours a week at our shop and they work perfectly fine, well they have been ok until now, four weeks they've been installed.The only negative is that the bulbs don't kick out much heat so you might need a jumper! Also they do make a slight noise when it's quiet but again, not an issue for us.Well worth it.

Okay, admittedly I purchased these in 2016 and only just got round to using them but zero out of 4 worked. I mean, not even a flicker. My lamp is fine as other manufacturer bulbs work perfectly. Just one of those cautionary tales of, if stocking up then test them first. I know it's too late to do anything about it but seriously disappointed. Won't buy this manufacturer again.

Decided to replace all the bulbs in my house with an LED equivalent and the savings so far are incredible.Bulbs do exactly as you'd expect and seem a fraction brighter than my previous 20w Halogens. Very Happy.
