There are a lot of candling lights on the market, and most are designed for and used by auto mechanics. Although they may be functional for checking under the hood, nothing says “snake” like the stems of those long black candlers.
Frightened birds, scattered and scrambled eggs, and severed candlers are generally the result. Ours features a cool to the touch bulb for safer observation of delicate embryos.

This is not just a “flashlight”, it's a medical diagnostic light with a “no heat" cool to the touch bulb. A standard “flashlight” will actually cook an egg before you have a chance to observe the embryo.
