1000 lumens is very bright. In fact, it's so bright that it can be uncomfortable to look at for extended periods of time. To give you an idea of just how bright 1000 lumens is, consider that a standard 60-watt lightbulb emits about 700-800 lumens. That means that 1000 lumens are about 25-30% brighter than a standard lightbulb. It's also worth noting that the intensity of light decreases as you move away from the source. So, if you're standing close to a 1000-lumen light, it will seem much brighter than if you're standing further away. In general, though, 1000 lumens is very bright and should be used sparingly.
