Philips Master LED GU10 Spot 4W : Brilliant LED (with no lag)

Energy-Saving Bulbs
1

Brilliant led (with no lag). I’m planning on gradually replacing all my old gu10’s with these, they are solid and even though they are models that are slightly different in look they all are exactly the same size. They overall look different from the slightly older led bulbs so in spot lighted fittings you can see the difference in look, even if they shine just as bright. Another thing which is great is there is no ‘lag’ from when the switch is flicked and the light turns on, in fact i reckon even i could fulfil ali’s boast by flicking the switch and be in bed by the time the light turns on (compared to the older generation of led). The prices of the individual bulbs may shock slightly and they most probably will gradually creep down as they get more popular. There are many different types so its worth looking at all the specs to make sure you’re getting what you want, but i’ve now tried out five different ones and they all work brilliantly and are mostly the same light and intensity.

As good as halogen but with the energy saving potential. Most led bulbs have to some extent a very much ‘whiter’ light than halogens, which are typically very yellow, or as some people describe it, ‘warm’. This has been a problem for people wanting to replace halogen bulbs with led bulbs for the cost savings, but not enjoying the whiter more clinical light. This bulb however has a very similar ‘colour temperature’ ( how white/yellow the light is) to a halogen bulb. Compared to my other led halogens it stands out as being much much more yellow. I imagine this took a lot of technical work to achieve, and it does feel like it brings led bulbs much closer to being mainstream. Light output is also very good and the spot size / brightness mimics a halogen well. In summary, this will appeal to anyone who wants an energy saving halogen and is offended by the usual whiteness of led bulbs.

Clean bright instant light, but horribly expensive still. It’s a little hard to justify the extremely high price for these bulbs. Yes they are bright, equiv about to a 35 watt halogen and bulkier and heavier too for ceiling fixings. Early adopters will love them; but they are likely to drop dramatically in price over the years (like cfls did)so you would be unlikely to ever re-coup your purchase price, unless you have these on all day long – then its worth considering. One interesting thing most people do not know about these bulbs,is they may be ‘dimmable’ but the effect is totally different from ordinary bulbs when dimmed. A ordinary bulb ‘yellows’ as it is dimmed (light spectrum output changes, ie the measured kelvin becomes lower)leds do not do this; so the cosy effect of dimmed lights is totally lost. In fact its more like squinting your eyes and wondering why it seems darker. I do not like that feature at all and neither does anyone i’ve tested this onso the premium cost for dimmable leds seems rather pointlessif you use them for a few minutes at a time, they will last a long time; but you will never re-coup the initial cost. However there is no figures on the life longevity to the electronics caused by switching on and off regularly (heat stresses components and the solder joints). Fluorescents terminate their lives much much earlier if constantly switched on & off. Here are the specifications for the Philips Master LED GU10 Spot 4W:

  • Philips Energy Saving LED Spot Light Bulb
  • 4 Watt GU10, 2700K Warm White, Dimmable
  • 275 lumen output, 900 candela, 40 degree beam angle
  • Delivers a warm, halogen-like accent beam suitable for spot or general lighting
  • 80% energy savings compared to 35W halogens. 40,000 hour life minimises maintenance cost

Plenty of light, no warm-up time and lower energy costs. I am gradually replacing all of the standard gu10s in my house with their led counterparts – not initially because of the energy saving but because i was tired of seemingly constantly replacing standard gu10sthe philips units have worked well so far, with no failures, and the light that they give is bright, smooth and certainly not a stepback from a normal gu10. One thing i have definitely noticed is that the fittings are a lot, lot cooler to the touch with these led units – my old kitchen spot fittings had been discoloured by the heat of normal gu10s, heat that is literally a waste of moneymy only reservation is that these are a lot more expensive than a standard gu10, but they are cheaper to run and a lot more convenient as they haven’t so far needed to be changed at all.

Alternative to halogen bulbs. We have spot lights in our kitchen, three lamp-fittings with three spot-lights on each. Until now we have used halogen bulbs and have been disappointed because they don’t last long and we have had to replace at least one of them every couple of weeks (which works out fairly expensive and on average the bulbs seem to be lasting about 5 months each). I was pleased to see that these led energy-saving bulbs have the same fitting so i am trying one to see whether it lasts any longer. As the cost of this bulb is 6 times as much as the halogen bulbs i am expecting not to have to replace this one for nearly three years. The light it gives out is clear and bright. We don’t have a dimmer switch so i can’t comment on what happens on this setting.

Reviews from purchasers :

  • Good light output
  • Good quality light
  • Light ok, but not instant on

Brilliant but a bit too costly at the moment. . I’ve got a fair bit of experience with led bulbs now trying a number of different brands and also a few different philips ones. The philips ones are brilliant i can’t praise them enough, clean and bright light, just as good as a halogen but with long term cost savings on electricity, they give off much less heat and the bulbs have a much longer life cycle, years. So yes the initial cost is very expensive but the savings you make over the life cycle of the bulb would more than cover that. However that said i think i will still wait until they are sub £10 before i replace all the bulbs in my house.

Much more expensive than other led brands. I received this free through the amazon vine review programmei 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.

Light ok, but not instant on. Light is fine, but it turns on like an old florescent tube, i. E there is a couple fo second delay before it comes on. Previous version of this bulb was instant on so have returned.

Dims very well with qubino zwave dimmer, dims very low. For some 2700k might still be too white, for me it is perfect in my modern house.

Much nicer light quality than the others. It is also very economical, considering the light quality. Has a slight delay in turning on, so i recommend placing it in fixtures where they are all the same type.

Provides wonderful light, pretty much indistinguishable from a regular halogen bulb but without the heat. If it lasts as long as other master leds, this might outlast the lamp the bulb is in.

Philips master led gu10 spot 4w (35w) – good compromise from the old yellow bulbs. Slowly replacing my yellow lights. I find this bulb a good compromise from the old yellow to the new harsh white lights out there. I used to like the relaxing tone of my dimmable yellow lights and found the new ones i tried out there very harsh cold clinical white. With replacing them slowly one by one (4 lights on one dimmer) the new lights look much better and even though they are only 4w equivalent to 35w they are quite bright, whilst still being able to dim very low. Upon replacing the 4th bulb in the dimmable set we found the 4th one flickered a little but we have found out that we need a different compatible dimmer switch. Philips sent us a list of compatible dimmer switches which states how many bulbs etc each different dimmer switch can handle etc. Really happy with these bulbs and im sure my electric meter is too 🙂 once it balances out the cost of the bulbs.

Great replacements for 35w gu10 bulbs. Great replacements for 35w gu10 bulbs. Usable in most applications, they provide a good light very close in colour to traditional halogen bulbs. Don’t forget that you may need to change your dimmer switch to one that is compatible with led bulbs and can be adjusted to get the full range of dimming. Uk/gp/product/b00c14mxxk but there are others available.

Due to the fact that i work in the construction industry & in particular electrical engineering it’s a widely recognized fact that when installing lamps of any variety, it’s a far better idea to spend a little extra on a reputable brand as more often than not you will save money & this lamp would appear to be the perfect example. I’ve sometimes chucked a super-market or diy store branded lamp into a fitting only to find it blowing far sooner than it should & occasionally had lamps actually damaging an expensive light fitting – having installed these philips spots in a john lewis kitchen fitting i’m more than pleased with their performance & additionally, the design is fantastic & even though you only really see the front face they look wonderful set into the fitting. Unless something proves me wrong in future i’d definitely opt for these lamps. At the right price of course.

Changed a 4 bulbs to these led one,s not the most prettiest lamp on the market. But the fact they only use 4w compared to 35-50w halogen ones and are still dimmable is great. Hopefully they will last a lot longer than the halogen ones. So far other led ones have been going for 1 year and not blown, there on for about 4 hours a day.

One of the better led lamps. 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). Probably, but only over several years. Let’s say it really is 35w-equivalent. Halogen means 1kw saved in about 32 hours. If it’s switched on for an average of 4 hours/day, that’s 46kw p.

Philips led bulbs are the best. They are the perfect replacement for power hungry halogen bulbs. And now they’ve gotten even better.Can’t say i see much more light output but the quality of the light is perfect and virtually indistinguishable from a halogen bulb. Just check if your dimmer switch needs replacing.

Philips master ledspot mv vs b&q halogen eco. 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.

If you look at the price of this against a standard bulb then you won’t buy itbut if you look at the length this bulb will last and also the fact it is 4 watts instead of 50 watts so the electric saving is phenomenal then you will buy it i have replace half my kitchen with these as the normal ones blow and you can’t tell the difference in light, the only thing you notice is less heat from the bulbs and also how i am now not having to change bulbs anymore. Very strongly recommended, think longer term and make the investment.

Very difficult product to review, it works as it should although this product should last a lot longer than normal gu10 lights so time will tell, i will certainly update this review in the future once it does eventually fail. Normal gu10’s seem to last about 6 months in our fittings.

Excellent replacement for halogens. Led lights seem to have come of age. Ok these are expensive to buy but when you work out the numbers the energy saving is so great that it easily pays for itself. If you have halogen lights or are installing new lights then i would suggest to anyone that they pay for these as they are so much better than halogens, cfls or incandescent lights.
