But I guess you have to look at it as an investment since LED's last a long time. So yeah the initial investment is nice...But the running costs and bulb change outs would probably make LED cheaper.

I saw some beast LED randomly while browsing unrelated merch and these things were like 2k.

What about your basic t5 (non-HO) light bulb expectancy?

Yeah I read and you should get 20k hours...Not the 4k db said. Maybe the shit brand I have lasts 4k lol. But still its pricier than metal halide considering those last twice as long. They do run cooler ill give them that.

Called those GREEdy cunts about where the fuck my warranty is at.
How these fucks gonna gimme less than what I paid for the unit?
I cant even find a 30pint dehumid for 144. Them cheap ones at walmart are 150.
I asked the bitch how they came yp with that #. Oh they use a average throughout the country and are unsympathetic to those who paid more.
Figure theyd use the MSRP value and id make out better.
Stupid chinese made.products.

Yeah because red algae will start to grow and their expensive corals die.
I did about 3 hours of research on photosynthesis last night. Was a tough fucking read. I felt learning what spectrums each pigment that is part of photosynthesis can absorb light at was the first step.
Chlorophyll A and B like blue and red light since their pigment is green. Peak absorption at 665 and 465nm for A and 640 and 450nm for B.
The carotenoids and other antenna pigments are yellowish orangish redish colored and can absorb greens and blues.
Was reading that past the 650nm mark these electrons can fluoresce and lose energy when they turn from an excited state to a ground state thats reemitted as photons of light. Intact chloroplasts generally do not re emit energy but will instead absorb it in a phosphate bond as ATP and NADCH2 or whatever.
This was an article from the mid 90s. I found a newer article related to weed that said all energies are stored as ATP or NADCH2 which help the plant create cellulose from glucose. Glucose is a string of 6 carb molecules CH2O(6) which is produced by ATP and NADCH2 from photosynthesis.
Shit makes my head spin.
I had to look up like every other word. Fuckers talking about eukaryotes and prokaryotes and symbiogenesis theory linking organelle found in eukaryotes to a symbiosis relationship of multiple prokaryotes(single celled organisms).
Was an interesting read.

oh and conjugated bonds...those mother fuckers make it all happen.
then electron clouds resonate and expand and absorb light energy.
fucking hydrophilic and hydrophobic structures and amphipathic natures that make reaction center pigments (Chlorphyll A) join antenna pigments to better facilitate photosynthesis by using light that isnt otherwise absorbed by Chlorphyll A but is by other pigments but still powers chlorophyll a tbrough energy transfers.

Yeah...and lumen loss. But i think that happens with all bulbs

I apparently went deep.
I heard they are making algae lamps. Apparently the chlorophylls absorb 150-200 times more co2 than chlorophyll found in trees and something about the biolumenescence of the algae release a glow that can be used for street lamps.
Be a good step towards reducing the co2 in the atmosphere.

Yes, @polyarcturus mentioned mv being the only real source of uvb long ago. Or his choice anyway.
