LED Tubes Light Output?

[imroberts]

I've been looking at LED tubes to replace my fluorescent kitchen lights. They're 1500mm T8 fitting.

I've fitted LED bulbs throughout my house and am very happy with them - I find the light much nicer than either traditional incandescent and especially more so than conventional energy saving bulbs which I find very fatiguing.

However, when looking at tubes, the quoted light output seem drastically different to fluorescent tubes. A 36W fluorescent seems typically rated at 5200lm whereas the 22W LED equivalent is a mere 2000W.

Is the difference really that stark or are they actually ok?

off topic a bit, but LEDs are so cheap to run, and in the standard sizes will be increasingly cheap to buy, that I think the cost advantage of 'tubes will go into reverse. If you buy a fancy LED "imitation fluorescent" today, when something about it goes wrong, it will cost more than if you had a few BC or SES lamps of standard conformation.

Those lamps designed for little halogens will soon be in the skip.

Are you sure about that? I see a 58W 5ft fluorescent tube of 5200lm

Or an 24W 5ft LED tube giving 3200 lm

58W of these LEDS would be 6.3 of them. Six would total 4836 lumen, which is near.

Though I find that LEDs seem brighter than their lumen rating would suggest.

I replaced a 5ft 58W fluorescent with a 22W LED purchased from LED-Hut. It wasn't cheap at just over £18 inc delivery. It is equally as bright as the fluoro it replaced, and does not have the annoying switch-on flicker.
