I have some of those lights. They are OK. I like them for the wide light output and they were the first lights to introduce me to this type of light. However, I prefer this type
They are about the same price. Owning both I almost always use the type I linked to instead of the other style. I find the ones I cited to be a bit more comfortable, they have a longer run time, I think they produce a bit more light overall and finally, the headband under the COB lights gets a bit warm in the first type. I gave both types to my mechanic friend as well. Based on seeing which he uses more I think he agrees with me.
