I am going to use it with my metal grinder and wonder if it's OK to have "open" design with halogen light or It's better to go for a real dust proof/water proof machinist light?
60% off! But, I don't like those parallel-arm lamps - they just don't seem to stay in the right place for me. I much prefer the goose neck style. It has a "J" type halogen bulb, which is probably the long, skinny kind. If so, I find those bulbs to give uneven light patterns. Or, maybe it's the lights/reflectors I've used.
Also, I find 50W (halogen) to be plenty for task lighting.
I've had an open light on my grinder for 30 (40?) years without a problem. I've never heard of a problem with them.
