We could install some Fluoricent lights just as work lights. But florescent light (TL) have also ver mediocre color rendering if you have the cheap/wrong ones. For judging the health of plants, we'd have to have lights with a high CRI (Color Rendering Index) of 90+. Normal cheap TL have around 60 witch translates into lousy color. Incandescent haloogeen lampen are actually better even. Their CRI is 100. Since we only would use halogeen for inspection, it might just be ok to keep doing that.
