That looks identical to one that I have that I've used in the past to build qrp ham radios (these are small radios with tiny discreet parts). That is a substantial magnifying glass that should reveal the day old larvae's smile. ;) I'm not sure about the light, though it is florescent I recall it does put out a bit of heat...you'd have to take care not to dry out the larvae and jelly. There might be enough natural/ambient light to use it without electricity. If I ever decide to try grafting I might just have to try mine out.
