Best one yet,
Amazon Verified Purchase(What is this?)
This review is from: 5w 80LED Energy Saving GU10 bulb 380 Lumens 50w brightnessI have 12 50W halogen GU10 bulbs on my kitchen ceiling, so have been looking for some sort of energy saving version for ages, however, all the LED ones seem to be too dull or don't spread the light correctly. I'm a bit too fussy on this as I like the room to be very bright.
Looking at these, it says they are about 380 lumens, and I think a normal halogen 50W is about 500'ish lumens, so I expected these to be slightly lower in brightness. However, this one was one of the very few that were "brave" enough to actually state the brightness which gave me some confidence. Also, as it has 80 LED's in each one (as opposed to some with just 3 very bright ones) it should spread the light out nicely.
N.B. Beware of bulbs of all different input wattage advertising that they are equivalent to 50W. How can they be? I've seen 3w LED bulbs and 4W LED bulbs stating this - someone is not telling the truth!
So, anyway, I bought one of these, and it worked fine. The brightness is very slightly lower than a 50W halogen, but not too noticeable. The spread of light is just a good as the halogen. So then I bought 3 more to see and make sure (as buying another 11 in one go is a bit expensive), and I'm still happy with the result 4 weeks later.
I would recommend these. For me, firstly, I was burning up 600W and the kids were always leaving the lights on, and secondly, a halogen bulb was always blowing every few weeks. I give this 4 stars (instead of 5) because the brightness is very slightly less than the normal halogens, but for the two reasons above it is definitely worth it. If there was, say, an 8W or 9W version of this 80 LED bulb, this would be perfect. I will eventually over the next few months buy the other 8.

Regarding input wattage & output lumens, LED lights are all different. 3 watt bulbs can give very different number of lumens because technology is constantly changing.
Read details of bulbs VERY carefully before buying.

Yes, however the efficiency of LED bulbs are generally between 80% and 90%, so I would expect a small variation, but certainly not a bulb of 3 or 4 watts claiming the same as a 6 watt one (especially when they don't state the Lumens).

One really needs to know at what height below the light the lumens are measured to do a true comparison. It all seems a bit vague.

To clarify on the equilivence to 50W bulbs.
50W is a measure of the power used. This power is made up of almost entirely heat and light.
Conventional halogen bulbs are very hot when switched on, therefore consume a lot of power.
LED bulbs are cold to the touch when switched on, hence they comsume far less power.
Therefore the watt rating of the bulb may not a good indicator of how bright it actually is.

There is an industry standard, which ensures that quoted lumens are always measured in a comparable manner.
