LED bulbs

LED bulbs are not what they seem to be. I have bought G9 LED bulbs online hoping to get higher wattage, brighter bulbs. However on measuring their current consumption claims of 9W or even 11W are actually nearer 2.3W or 2.9W

LED's use less current (and therefore £) than normal bulbs.

for the equivalant W, the idea is to give the same light output, but cost less to run.

I recommend you buy minisun G9 LED (available on ebay)

How are you measuring the current? I'm not sure what method LED bulbs are run on, but if it is a rapidly pulsed current, that could fool the measuring instrument and make the readings inaccurate.

Why did you buy LED bulbs hoping they would consume more electricity?
:huh:

Which G9 LED bulb did you exactly buy that was rated at 11W? :huh:
Most of the G9 LED bulbs I can find online are in the range 2-4W

Light output is measured in lumens.

The main difference I noticed when I changed all lights in my house (3 bedroom semi) to LED's is that my electricity usage reduced (on average) by 2 kWh per day so about 730 kWh in a year. This was a noticeable reduction in my electricity bills of approximately £100 per year. I also started to use a tumble dryer not long after the LED's were installed so my savings are actually probably higher than £100 per year as a result of switching to LED's. Therefore, they do make a difference in terms of energy efficiency and they have made the house look more modern so personally I am pro-LED.

In terms of lighting, the warm LED's are not as a bright as my previous standard lightbulbs but nothing significant and I quite like that they are not as bright. The cool LED's in the bathroom and kitchen are noticeably brighter and part of me wishes I got warm LED's in the bathroom now.

If you're buying cheap LEDs off eBay, Banggood or similar, then it's pot luck what you are going to get. The manufacturers realise that most people will never test the lamps, so they can get away with shipping ones of much lower power than claimed.


If you want anything decent, buy a named brand from a reputable retailer.
