Philips Ultra Efficient - Ultra energy saving lights, LED light source, 40W, P45, E27, Warm White 2700 kelvin, clear

Does what it says on the box.Was perfect for my outdoor porch light.Good price, looks great with a warm glow, low energy consumption and a good estimated lifespan.

Nice light and more efficient

These replaced four older 4w bulbs in dusk-dawn outside lighting. Even though that are almost half the energy usage the seem brighter than the old ones! Quick calculation says each bulb use 8.3 KW/h less energy over a year (on average 12 hrs every day), which is ~£2.5. So they will pay for themselves in ~3 years! And if multiple bulbs fail significantly before ~10 years (50,000 hours) then back they go for a full refund because that's what they were sold as - life expectancy 50,000 hrs.

Used in my lamp for months, it has a very pleasant hue but does not stay as bright as other bulbs I own. I presume this is a byproduct of the energy efficiency.

verry energy efficat and means that i save a lot of money once it is on

Value for money, durable and cost effective.

Changed the old ones with these ones and are really good for saving energy.I was having similar ones as LEDs. These ones improved the savings with roughly 10%.Of course, it depends on usage.I should have chosen the 8W(60W) ones due to reduced lightning.Anyway, I am very happy with hem.

Fabulous bright bulbs would definitely recommend
