3.0 out of 5 stars Philips MASTER LEDspot MV vs B&Q Halogen Eco 16 Jan 2014
Vine Customer Review of Free Product (What's this?)
Imagine replacing all the GU10 Halogen bulbs in your home with new LED bulbs that use just a seventh (14.28%) of the energy and last 40 times as long. Not only would your electricity bill be significantly lower, you wouldn't have to get up on a step ladder to change your bulbs as often. LED bulbs have certainly come a long way in the last few years, so is it finally time to make the switch?

To answer this question, I thought it would be useful to compare this 4W Philips MASTER LEDspot MV bulb to a standard 28W (35W equivalent) B&Q GU10 Halogen Eco bulb. What I discovered is that the technical characteristics of each bulb, printed on the packaging, cannot be trusted.

Colour temperature (measured in K or kelvin) is something to pay attention to when buying LED bulbs, because they typically give off a cold, blue, clinical light. But, if you can find an LED bulb that matches the colour temperature of a Halogen bulb, then theoretically it should look the same, right? Well, this Philips bulb has a colour temperature of 2700K and is labelled as "Warm White". However, the light it gives off is actually bluer than the light from the B&Q bulb which, at 2800K, actually has a higher colour temperature! That's not to say the Philips bulb looks bad, but the ambience it creates isn't quite as relaxed or as cosy, compared to a standard Halogen bulb.

Beam angle is something else to pay attention to when buying LED bulbs. This Philips bulb has a beam angle of 40˚, whereas the B&Q bulb has a narrower beam angle of 36˚. So, naturally you'd expect the Philips bulb to illuminate a wider area, right? Nope. It turns out the Philips bulb is the more focused of the two, with a narrower beam that limits light to a smaller area, creating sharper shadows.

4.0 out of 5 stars Much more expensive than other LED brands 20 Feb 2014
Vine Customer Review of Free Product (What's this?)
I received this free through the Amazon Vine review programme

I can honestly say that I would not have paid this much for a single lightbulb, LED or otherwise. I have replaced lots of lightbulbs in my home with LEDs - both dimmable and non-dimmable varieties and over the last couple of years have noticed clear improvements in the technologies.

The warm white colour of this bulb isn't as warm as the light output by bulbs I had purchased from another brand, but is noticeably on the yellowey side of the spectrum. It's a decent bulb and over a few years would pay for itself (had I purchased it).

However, there are less expensive LED halogen replacements (including dimmable ones) on the market. These too switch on immediately, generate warmish white light at roughly comparable levels to traditional halogen bulbs, yet use far less power. The only significant difference I can find between this bulb and ones costing less than half the price is in terms of projected lifespan. The Philips bulbs are rated for around 25 years of life, whilst my cheaper bulbs are rated for around 20 years. Given the rapid improvements being made in this area of technology, I think I'll stick with buying the less expensive bulbs for now.

4.0 out of 5 stars One of the better LED lamps 5 Feb 2014
Vine Customer Review of Free Product (What's this?)
I’ve tried a number of LED lamps – GU9, GU10 and others. This is one of the few that I've been happy to continue using. With others, the output often doesn't match the claim, the light characteristics are unpleasant, or they’re too big. This one is far from perfect but I find it acceptable and like the fact that it’s dimmable.

Philips claim 275 lumens and 35W incandescent equivalence; I’d put it closer to 30W, which the light meter in my camera seems to confirm when I photograph objects under it.

Some people complain that the light it produces is too cold but I like it, especially for task illumination – reading, sewing, etc.

The size is fine – it replaced a halogen in a downlighter without any problems (but NB some older transformers may be unsuitable for LED lamps).

It’s expensive. Will it pay for itself? Probably, but only over several years. Let’s say it really is 35W-equivalent. The 31W saving vs. halogen means 1kW saved in about 32 hours. If it’s switched on for an average of 4 hours/day, that’s 46kW p.a., which, at current rates (no pun intended), means about 6 per year. Even ignoring the cost (and hassle) of replacing halogens every so often, you get your money back in three years or so, and it will last 20-30 years, if the claimed 40,000-hour life is correct (not that I’m likely to be around, to find out!).

If you’re keen to save money, long-term, or just cut your carbon emissions, do buy one of these to try.

5.0 out of 5 stars Excellent 31 Dec 2013
Vine Customer Review of Free Product (What's this?)
Excellent build quality and look very smart. I have normal Halogen spots in various places in the house, and they consume quite a bit of electric, get very hot, and seem to blow regularly. These LED spot bulbs answer all those questions, consuming some 85% less electric, do not get excessively hot and have a life expectancy of 15 years.

This is the 4W (equivalent to 35W) warm white (2700K) version. It's incredibly bright, don't look directly at it. I would say it's brighter than a 35W Halogen, but the light beam is more focused, so you get much more of a `spot' compared to Halogen. The warm white is a yellower shade than normal halogen spots, and are the ideal replacement for the existing standard Halogen bulbs in my bedroom, I found it too yellow for the living room.

They do dim, but I'm using a standard, cheap and cheerful dimmer, rated at 60W min, I tried dimming with a 6W and 3x4W LED bulb (so 18W total), and it only dimmed on the first 5 clicks of the 15 click range, providing 5 big steps from very dark to full bright. Adding two 50W Halogens to the same 4 spot rail, the dim range increased to 7 clicks, indicating the LED bulb load was too low for the dimmer to work correctly. I probably need a more advanced dimmer, but these are generally quite expensive.

This bulb claims to have a better dimming range, compared side by side with the older bulb, but still using the cheap dimmer, I saw no difference in dimming performance.

All in all, a great bulb, especially for bedrooms where the colour is right, but remember to consider the still limited dimming.
