led lighting vs floresant lighting

[rooster31096]

i have a 55 gallon planted tank 4' x1'x2' dim. i would like to know if the led are better for my tank than flo.lights if they are had tell how many led lights i need. i have a homade 4 strip t8 flor. 128 total watts. can any help me.

i hv seen marine tanks using LED lighting, quite impressive, got the 'shimmering' effect some more.

i think it might be a good idea to try, less heat, less power consumption.

i saw it at aquamarin, corals growing well. should be also applicable to plants

Hi,

I've hear that for growth of aquantic plants, florencent(hope my spelling si right) lightings are better than LED. Is this true? Any advises from any brothers out there? Thanks

well, without knowing the lumens that the LED is emitting, its very difficult to gauge.

Hi bro, for flo. lights the 4 feet consume ard 38W each, normally a standard 4ft LED T8 tube consume only 18W which contribute to around 1800lm which is sufficient for a fish tank. Reason why ppl feel that LED T8 is dimmer then traditional flor.tube is becos LED lights travel in straight line and it does not works like traditional T8 that have a light angle of 360 degree.

but if you going to replace remember to remove the ballast and starter.

i am not sure if i am able to post here but admin pls let me know if i had to remove the link.

Hi bro, indeed is the truth, Flor. tube emitted ultraviolet rays which is like sunlight which help in the growth of plant. Flor. put out more light in general, but a large amount of light in spectrums that arent used in photosynthesis. So by using red and blue leds in the 660 and 450 spectrums creates just the right lights for what they need.

Here are some simple basics for (I would dare say ) all plants:
Leaves (or the green parts; ones that have chloroplast ) of plants need Carbon-dioxide and water to produce its food with Oxygen as a by-product. I would like to repeat that it occurs only in the cells containing chloroplast.
Roots consume this food; thus it OXIDIZES this food; releasing energy within the plant. This oxidising occurs in the same manner it occurs in every living cells that I am familiar with: by burning. So it needs oxygen (Also a good reason why well drained soil is a must with most potted plants ).

When there is light, the plant produces food, when there is no light the plant only consumes. But the point here is that even when there is light, the plant still consumes food thus uses oxygen!
The roots are in the dark and they need oxygen to be able to burn food and produce growth.

I believe the basic thing we are after here is to have the plants 'grow'.
Thus: have no worries that in a completely closed environment the plant shall manage to live pretty well without a need for CO2 additives.

There are very ground reasons to why producers do not invest in any carbondioxide supplements. Until new series of tests prove to be completely contrary; the basic rules of growing plants are based on the facts stated above.

One could argue over the green rooted vegetables most commonly propagated in closed environments. But as far as I know it: none the less the ground rules still apply.
