I'm trying to learn some basic modeling in blender, working on a long concrete hallway. there are supposed to be fluorescent lights on the ceiling of said hallway, and i made those out of emission+glossy shaders in the mesh itself. but this is resulting in an extremely noisy render, even at 1000+ samples.
I've tried changing clamp, filter glossy, caustics, nothing seems to be effective. might just be my pc, not sure.
here's the .blend file: https://mega.nz/#!LUdUGIaB!QFpdxi3DafcFbm5hpdU-qgo8K-LmMP5TZKD1lagCrK0
OS: windows 10 pro 64-bit
CPU: AMD Athlon II x4 640
Motherboard: MSI 870-G45
GPU: MSI NVIDIA GeForce GTX 650
it might just be too dark i dunno
