Not all led's are made the same, and if you have an led thing from a walk in store that says it has 100 led's... or even just more than a single LED inside of it... it's just a bunch of project lights and a marketing gimick. Look for things with a 3W cree LED and such if you want real power. About 300 focused beam lumens is good for the average egg, but thick dark shells are often going to be a beast if you're on a lighting budget. The hardest part about lumens is getting them to all go in one direction.
