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.Read more ›
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.
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.
What you get for your investment is a very well made an elegant looking bulb that fits directly in to an existing 240V GU10 halogen bulb fitting with no modification needed. LEDs are low voltage devices but this is a "chip on board" device that steps down the mains voltage internally without the need of a separate transformer. The bulb runs cool and the light output is indistinguishable from my existing halogens - a point that impresses me greatly. The perforated ring around the lens is a grey silver colour, whereas most folks have white ceilings and white fittings. I wish the ring was white so it did not stand out quite so much. The ring is there for cooling by the way, and it's a common misconception that LEDs do not heat up. They do, but a lot less than halogen. Lack of cooling can over time cause an LED bulb to fail prematurely or the light to gradually change colour from warm to cool blue, so clear any stray insulation directly behind your fittings.
Overall this lamp is superb, and I'm delighted the era of viable LED lighting is here at last!Read more ›
