Sigh.
6500K is the spectrum of light which the bulb is running.
LED and t5 are both either red or blue. You pick the spectrum.
Red for color, Blue for growth. An equal balance is desired of both from plants.
6500K is white- Blue light.
3000K Is Red spectrum.
LED will last longer, and be much more expensive.
T5H0 you will need to replace the bulb at least once a year. 10$ each a bulb in my town.
(Even if it comes on, doesnt mean its still running at max efficiency.)
I dont have any experience with LED. However, the experience that I do have is buying a 400 Dollar rig
for my salt water corals, only to have it not be enough light and become a waste of space. Others report success with
LED, However I simply do not like them one bit.
ps- links are fine.
PSS - it will be Extremely difficult, if not nearly impossible to grow Nepenthes
with just 2 t5h0 bulbs. You might get away with beginner species, but the picker ones are much
more hungry. The same for dews. The more light you dump on them, the happier, larger, and more colorful
your plants will be.

I own 4 of these. ^ Generally about 50$ at home depot. (2-Light 14-Watt White Fluorescent Grow Light) (one foot bulb)
I use them STRICTLY for overwintering plants. I tried growing my nepenthes with them,
but they do simply do not get the job done. They will keep your plants alive, but they wont flourish,
or color up. They eventually stall out, get weak and wither away. (And you practically have to have this light directly on top of the plants for it to actually do anything.)

And this is one of the 2 monsters in my Lighting army that keeps my Vivarium chambers alive and growing.
Ive kept them in 90+ humidity for basically years on end, and are very sturdy workhorses. IMO
The bare minimum for growing ANY plant species. yearly maintenance is 40$, just the bulbs.
They ALSO include reflectors behind the bulbs, making them at least 35% more efficient.
The home depot ones do not have reflectors of any kind.
(IF you think about it, the second light is twice the length of the first one, with 2 more bulbs and REFs. In my book, that makes them 1/4th as cheap as the alternative, and much more of an economical choice.
In my book, You should bite the bullet and buy the expensive lighting fixtures right off the bat instead of the cheap ones, because it really sucks when you have to go back and spend even more money on lighting,
after discovering you wasted money on something that barely works.
