I am curious about the LED lights lately since they are starting to get more mainstream.
I have a t5 tek light fixture that I use....it's output is rated at 10,000 lumens and uses 110w of electricity.
Anyone have any idea what size LED fixture in terms of power consumption would be comparable?
Far as what LED fixture I would like.....most likely the 7 band ones.
From what I have read the benefits are longevity and allegedly canopy penetration but one would think the wider spectrum may be beneficial as well.
However nowhere can I find a brightness comparison..very few LED fixtures I have seen list this...meaning if it takes a 225w led fixture to put out the same light as a 110w pl t5 ho tek lamp then I really do not see a benefit for this application at this time for me.

No problem. You need to check out: www.ebay.com/itm/Pro-7-Band-Hydroponic-600w-Hydro-LED-Plant-Grow-Light-Flowering-IR-UV-/201127408319?&_trksid=p2056016.l4276 I have had a 240W with the exact same specs growing my collection of rare neps in my highland chamber and it produces lots of PAR. Photosynthetically Active Radiation. This is wave-length of the light from the Sunshine in which plants use to do different things at different stages of life. The above link I have given you is a 600W version of what I have been using. I just got the exact one in the mail. I have researched these LED lights for months before I came to rest on this blend of colors of the spectrum.
Lumens vs. PAR readings and electronic instruments. If you have an instrument which measures Lumens, then forgive my bluntness, but I am afraid it is worthless to your plants but great for if you need to take a photograph.
Consider how our (human) eyes cannot see infrared light and we need special cameras to see that so, what these LED lights do that no other grow lights do is they utilize only the spectrum of the sunshine that plants need to grow - eliminating all other parts of the spectrum which are useless. The metal halides, sodium, CFL, and FL lights output tons of worthless spectrum for plants, wasting energy, creating lots of heat, and increasing energy bills like crazy. For a perfect example: I have 2 5000 Lumen 85W CFL lights I am and have been using to grow some non-carnies. When I first got my apogee meter, I tested these lights and it was only when I was literally touching the sensor to the light did I get a reading comparable to what the LED hits at about 2 feet away. When I measured at plant level, it was darker PAR than there is on a thundercloudy day of 18 PAR!
The LED light above is BLINDING, MONSTEROUS, extremely powerful and the company selling them: well, I have been monitoring them on eBay for a couple months now and it appears that as a result to not being able to sell, literally, any of these lights; they are now putting some up for auction! DO NOT LOSE OUT ON THIS DEAL. This light is worth WELL over $600!!!
A word of warning though, work your plants into this light, otherwise you may sunburn them as I did my little N.Villosa!

plantguyty1: Does anybody need pollen? I have N. Miranda it's the first time it flowered for me so I do not know if its sterile or a good candidate. Is there anybody with an active female that would like to give my pollen a shot?

thatoneplantboi: Hey guys, I'm new to growing nepenthes, I'm getting a mini indoor greenhouse to grow them in. What kind of light should I use for them? Also, if you could provide a link to a product, it would be very much appreciated

borneo: Yes, they work superbly. But you don't need expensive lights, cheap ones work well too.
