I just have to put in a plug for my new high-powered flashlight. It is 100 lumens and 6 LED's. It cost about $20 at Lowe's and I'm pretty sure you can find something similar at HomeDepot. It put's my my mini-mag to shame! I candled all 51 remaining coturnix eggs in my incubator when I took them out of the auto-turner, and I was amazed at how well I could see the air sac level and dark area of the egg vs. the clear or murky ones. I can even see through my dark green EE eggs with this thing. If you're going to candle coturnix, I highly recommend getting one of these! We made a one inch paper cone that DH taped to the end of this small light in order to narrow the opening even further for the quail eggs. The tip about the candler came from Mahonri's post when he was hatching marans eggs "Well, we went to Home Depot and bought a light that does 105 Lumens... it has a caution sign on it as it can damage human eyes!, so we could see through EVERY egg, including the Cuckoo Marans!"
