I tried LED GU10 some years ago and the results were disappointing so went to cold cathode however over the years this has faded and gone yellow so was replaced with a standard quartz unit.
Then my wife went to Pound World and came back with some GU10 and MR16 0.58W spot lights which on seeing wattage I laughed at. However stuck them in and was surprised how bright. Using as bedside lights they were good enough to read by.
In the bathroom 4 x 50W MR16 were replaced and the results were a rather dim room as one would expect but good enough and since a rather old system using a transformer not an inverter no real problem.
Next was a visit to Lidi and I got two candle type E14 bulbs to use in desk lamp next to key board. Finding one of the 8W globe type bulbs had blown I used one instead in main living room light and was rather surprised at the output. It seemed brighter than the 8W CFU that it replaced but only 1.4W. I aimed camera at the bulbs and 1/30 second F3.5 ISO 140 was shown with both lamps 8W CFU and 1.4W LED and the LED does not have a soft start. I did wait 1/2 hour before measuring.
This was rather a surprise I had considered LED and CFU to be on par so question are my CFU all faulty or are LED lamps better?
I compared at my desk the folded 11W florescent and the 1.4W LED and as expected the 11W is giving far more light out. If I had just one bulb in living room I would have blamed the bulb but 10 in living room and 8 in dinning room the dinning room is a different make and slightly brighter bulbs but this does to me raise the question in general are LED lamps better than CFU?
I also did the CD test tilting it to see the colour spectrum and the CFU gives three well defined colours where the LED there is a gradual blend between each colour likely better for my photography.
I did after look on internet and I do see claims that LED lamps are near half the wattage to CFU to give same light output.
