Philips 71400300 - Lampadina LED PHIL CorePro line

This is not bright enough for the purpose I bought it for replacing a Halogen bulb, understandably this is 2000 Lumens on the box so it probably is correct to spec. I wish Phillips had a 3000 Lumens version, I combed through Amazon but could not find a phillips LED R7s 118mm with 3000 Lumens. I bought a 3000 Lumnes LED (Luxvista R7S 118mm LED Light Bulb Dimmable) from a random manufacturer here on Amazon at the same time I bought this one and it is very bright and to the standard I wanted for the purpose of the lamp. I was sceptical of buying an LED from a random name manufacturer due to horror reviews I have seen here on Amazon where some of them burnt out into a smoke. Will be good for amazon to stock brighter versions of the phillips LED (hence 1 star less).Lastly, thanks to Amazon reviews I found out I could replace my halogen bulb 240w for my upright standing lamp with these LED 14w bulbs ....JUST WOWWW! It is ridiculous that sellers (aka John Lewis in this case) do not give this information on their page when you purchase the lamp and only give recomended bulb as the halogen 240w power guzzling bulb, same goes for the manufacturer's docs.

I have a beautiful pendant uplighter in my kitchen but it has always been quite energy-hungry with three R7s bulbs. Over the 14 years that I have had it I have gone from using 200W halogen bulbs to 160W, to 120W. When the 120W bulbs gave up the ghost, I was keen to find some low energy LED replacements. Having had some poor experiences in the past with LED bulbs from unknown brands, I was keen to go with a reliable brand like Philips. I am very pleased with the results. These work very well and are extremely bright at full power - incredible for just 14W!I had to replace my old dimmer switch as both the switch AND the new bulbs buzzed noisily when dimmed. After some research I bought a Varilight V-Pro JQP401W dimmer switch, which goes from 0-120W, so fine for using with three of these 14W bulbs. The new dimmer works very well with these bulbs, with no more buzzing from the dimmer or the bulbs. It also has a very good dimming range from very low to full power. The dimmer switch has various programmable settings, but I found it worked perfectly with the default settings. (Note that Varilight has several different series of dimmer switches, but it's the V-Pro series you want if you're looking for no buzzing.)Overall, these bulbs are certainly not cheap, but I'm very happy with them. The quality of light is great for a kitchen/dining room, and the energy saving over equivalent halogen bulbs is fantastic. I'm expecting these to last at least 5 years, which will make them more cost effective over their lifetime.

Depending upon where you look, the spec of these tube replacement varies...which makes it difficult to be sure about what is being purchased. However the main points are that it is a 118mm tube replacement, well made, quite heavy, it IS dimmable and is quoted as a 120W replacement. The two I bought easily replaced the two 120w tubes I was using so in terms of running cost, 240w down to 28w...pretty decent. But very expensive. Payback on an intermittent use basis is unlikely but if you take the capital cost on the chin, the ongoing running cost saving is real.Depending upon your light fitting, the thing to be aware of is that the led lights are not all the way round. I’m not sure what the coverage degree is...looks like say 270 degrees and because the LEDs themselves are arranged in lines along the length of the bulb, and there’s a space between rows, the light isn’t radiated around the full 360 degrees like a halogen tube. The fitting design will affect whether you can take advantage of the full 120w the bulb says it produces. In my case, not all the rows of LEDs shine outwards so I guess the effective light output is less than 120.But having said that, the light still works very well. It dims reasonably smoothly and the quality of light produced is certainly as good as the previous halogens. So although not perfect in my case because of the light radiation angles, it’s still pretty good and I don’t regret buying them. I think depending on your situation, they are worth 5*. I would buy them again.

Not quite as bright as claimed, but OK. The dimmer function does work, but there is a slight hum if it is not off or fully on.

This bulb does not last as it says - and when asked to replace an obviously defective product the seller just simply ignores the message. Avoid this item, avoid this seller.

Bought the 14 W Philips CorePro LED Linear lamp to replace a 200W halogen lamp in an uplighter. Given that the rated output of the 14W LED is equivalent to 120W of incandescent/halogen lighting, I expected a drop in light output - and so it has turned out. This isn't too much of a hassle as I rarely had the uplighter on full output when fitted with a halogen bulb, preferring to dim it down to roughly half the output. However - the lamp buzzes loudly when dimmed, so now its all or nothing.The light output quality is OK - it's claimed to be warm white, and I'd suggest that it is on the cool side of that, but not unacceptably so.Obviously the main reason to purchase this lamp is to save on electricity costs, and I'd say this ticks the boxes without excelling in any way. Build quality seems very good, by the way.

Almost lasted 3 years. Throughout its life cycle however, it did buzz if you didn't give it full power, which was really annoying because it is audible in a decent sized living room.
