Good functional bulb at a price. I can confirm that this bulb is roughly equivalent to a 30w-40w halogen. The colour spectrum i find to be a little whiter that a conventional bulb but would still consider it to be fairly warm. . Not too harshthis fits fairly well in standard gu10 halogen spotlight fitting, however it is worth noting that it is slightly longer than a standard bulb meaning it’s not perfect. I can’t comment on the dimming range as i’m using it in a non-dimming installationoverall i’m quite happy with this item & would certainly consider changing all by halogens for this led. If only it was much cheaper. At the time of writing £26 rrp per bulb seems very steep so loses a star.
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.
This bulb certainly has a premium build and finish, and feels weighty and robust. It fit snugly into the light fitting, and gives a nice quality of light. Slightly paler than a standard halogen but good coverage and perfectly bright. If the energy saving and lifespan are as claimed then this should pay off over it’s lifetime even though it is expensive.

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.
These philips led gu10s are among the very best on the market. The warm white (2700k) variant produces a superb quality light, bright with a hint of warmth. If anything slightly better than the halogens they replace. This 4w bulb is equivalent to 35w halogen and is really too dim for use in the kitchen in my opinion, with a 50w equivalent being a better choice. In a bathroom or dining or living area however they are perfect, giving a bright useable light without being too brash and blinding. These lights feel highly engineered with their silver parts and ventilation holes. That doesn’t really matter when they’re up in the ceiling, especially as they should supposedly last for years. Brilliant quality lighting and the final nail in the coffin of the halogen gu10.
Reviews from purchasers :
- Good light output
- Good quality light
- Light ok, but not instant on
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.
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.
