Philips GU10 Spotlight LED Bulb Dimmable DimTone 3.7W (35W Eqv) Warm White

Philips MASTER DimTone LED GU10 spotlight light bulbs are designed to mimic the behaviour of dimmable halogen and incandescent spotlights, while eschewing their lack of efficiency and minimal lifetime.

Traditional light bulbs have a tendency to shift towards a warmer colour as they dim while LED traditionally maintains the same colour. DimTone technology successfully mimics this behaviour while delivering all the efficiencies and reduced maintenance costs associated with LED.

Running at maximum output, this mains voltage GU10 spotlight option emits a standard warm white beam, equivalent to a 35W light bulb. This changes to a much warmer white as its output reduces under dimming, making it a popular choice for environments that require a warm and relaxed ambience such as bars, restaurants and so on. The amount of energy consumed by the light bulb, though already minimal, also reduces under these conditions.

This particular example is compatible with a broad range of dimmer switches and retrofits directly to existing GU10 fixtures. It diffuses its light within a 36° beam angle.

This spotlight lamp is traditionally known as a PAR16 with a GU10 2-pin twist and lock (10mm apart) base.

Here at SimplyLED, we want you to be able to buy with confidence both in ourselves and the products we sell. With this in mind, a number of our bulbs carry a specific warranty that ensures you can do exactly that.

Any LED or LED Smart light bulb bought from SimplyLED carries a 24-month warranty.

If you should purchase an LED light bulb from SimplyLED and have it fail, break or develop a fault at any point within the timeline stated above from the date of purchase, we will happily replace the item or offer a full refund, depending on your wishes.

In instances where large numbers of bulbs fail within a relatively short period of time, we may ask you to return them to us so that they can undergo testing to identify any potential issues.

What doesn't our warranty cover?

In any instance where your bulb has developed a fault, we will do our utmost to replace it or offer a full refund (provided the item is still within its stated warranty period). However, if it becomes apparent that the product has been misused, tampered with or modified in any way, we will view this as having voided its warranty.

'Misuse" includes, but is not limited to, incorrect operation by the user, use of non-dimmable bulbs on a dimmable circuit or connection to or operation with an unsuitable power supply. 'Tampering' or 'modification' can be interpreted as any activity designed to alter the product in such a way that it can be used in a manner that wasn't intended by its original design. This can include rewiring, removing plugs, home repairs or changing components. Unfortunately, we won't be able to replace any item that has undergone any such process.

If you have any further questions about our Warranty or Returns Policy that aren't addressed on this page, please feel free to contact us.
