Late to the party, but I figured I'd offer some pointers.
I acquired a similar one than what you had in the original post. https://www.amazon.com/gp/product/B07WV ... UTF8&psc=1
to be precise. It is "underwhelming" to say the least. I have it for a mini fish bowl terrarium, and the bulbs even at full power need to be within 6" of the plant or it doesn't do anything for the plant. Better than nothing, but only marginally.
Wanting to upgrade, but not go big, I tried one of these https://www.amazon.com/gp/product/B07NN ... UTF8&psc=1
and I'm pleasantly surprised. It's a heavy bulb, and it puts out some light. I started off putting it in a desk lamp https://www.amazon.com/gp/product/B07R5 ... UTF8&psc=1
but the bulb was too heavy (the lamp kept falling over) and it kept it too close to the plant. So I put it in a standing floor lamp I got at Lowes. I was able to put 3 different 1020 trays of plants under that light, about 3' away, and the plants seemed to love it.
Just recently I decided to try and upgrade to a "real" grow light. Most of my carnivorous plants don't need a TON of light, but I'm building up some indoor hydro plants too, so more light is preferable. I was really close to getting either the Mars Hydro https://www.amazon.com/dp/B07PLYR5HG/?c ... _lig_dp_it
or the SypderFarmer https://www.amazon.com/dp/B07TVD1Y3K/?c ... _lig_dp_it
, but ended up going with a light by Florawave light by Carnivero instead (https://www.carnivero.com/collections/f ... 9017689201
). I wanted my dollars to support a fellow Carnivorous Plant enthusiast, if I could.
I can tell the Florawave light works great for carnivorous plants, but doesn't have the power the MarsHydro or SpyderFarmer would (it's also half the price, for what that's worth). I also won't be able to continue to grow my hydro vegetables and my carnivorous plants under the same light much longer. I have to put the Florwave light about a foot or 18 inches above my plants in order to get enough light for the celery I'm growing, but at that height some of my nepenthes are starting to blush. But we'll see. Maybe I'll get a MarsHydro at some time in the forseeable future.
But I think a MarsHydro would be a bit of an overkill for a dorm room with a VFT. Just my two cents. Personally I'd go with the GE bulb I mentioned. Get a cheap light fixture (or a swivel shop light fixture) from HD or Lowes and it'll provide plenty of light for about a dozen VFT or Sundews.
I hope that helps!
