## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect condition
*by K***Y on 7 September 2020*

Great product fits perfectly and has a nice white/warm colour to it came in perfect condition

### ⭐⭐⭐⭐⭐ Excellent cool-white bulb
*by C***M on 3 September 2020*

I received the 2.5W cool white 4,000K version for review. It’s a very good compromise between warm and daylight white – just right for reading or task lighting, without any tendency towards blue. We’ve used it in a bedside light. It does seem as bright as a 25W incandescent. The CRI of 80 isn’t the best but is fine for most purposes.This is made in China, just like nearly all the LED bulbs you’ll find. I feel, though, that with a western brand I can at least trust the specs. Osram doesn’t seem to be suggesting unrealistic lifetime or exaggerating the CRI. I’m very happy with this and would buy again.

### ⭐⭐⭐⭐ A good money saving alternative to tungsten or halogen bulbs
*by M***K on 8 September 2020*

LED's have very much become the standard for light bulbs over the last couple of years and for good reason too - they are so much cheaper to run than conventional bulbs and last so much longer too. For example, this bulb uses 2.5W of power and has a stated light output of 250 lumens. To achieve a similar light output from a tungsten bulb, you would need a bulb with a power rating of 17W. As such, this bulb will save 14.5W of power for every hour of runtime.If it is assumed that electricity costs about 18p per unit (kW/h), this means that this LED bulb will save about 0.26p for every hour it is used. Whilst this might seem tiny, it very quickly mounts up i.e. £2.61 over the course of a year (assuming 1000 hours of use per year), at which rate, the bulb should last 15 years. Accordingly, the initial investment of this bulb should be very quickly recouped and very quickly provide significant savings.As mentioned, this bulb is equivalent to a 17W tungsten bulb and as such, it is quite dim, probably only suitable for ambient lighting. It is also quite similar in size to its tungsten equivalent (3.5cm in diameter x 10.0cm in length) and as such, it should be suitable as a like for like replacement in most circumstances.One consideration which is relevant to LED bulbs which wouldn't have been relevant to tungsten bulbs is the colour temperature. There are broadly three main colour temperatures which LED bulbs are produced in, these being 2700K (warm white), 4000K (cool white) and 6500K (daylight white). This particular bulb has a colour temperature of 4000K (warm white) and personally, this is slightly cooler than I would like but still perfectly acceptable.Whilst in use, the bulb remains reasonably cool to the touch and given that heat is probably the biggest cause of premature failure in LEDs, this provides reasonably confidence that the 15,000 hour lifespan should be achievable. Clearly, this is not something which I can confirm as yet (otherwise my review wouldn't be available for quite a number of years).As a final point, the title of this product makes reference to this bulb as having a colour temperature of 2700K (rather than 4000K). Whilst a version of the bulb may be available with this characteristic, it is incorrect for the version of the bulb which I have received. Accordingly, make sure you chose the correct option on the Amazon product page, to avoid getting a bulb which is different than expected.
