I tried to catch up on this thread but it's just going too fast so I only made it about half way so sorry if someone's already covered this.
We talk a lot about sf but we never talk about
viparspectra. Other than the fact that they're made in china and the lights don't have uv, I really don't see anything wrong with their full spectrum lights. I would honestly rather a
viparspectra light than a
hlg at right now. (I have a small tent so I can't say anything about the bigger lights.) They're the only small light to have actual heat sinks. They have a good number of diodes/w, they have good diode spacing, spectrum... And if anyone's curious if all that stuff makes a difference, I have an xs2000 and the diodes and driver hardly get warm.
I'm really curious why people don't use them.
