BoliOptics 10W DC 12V Oval Incandescent Microscope Light Bulb Replacement BU99011111

I welcome back to ELLs yes we're gonna go over how to change a bulb today we're actually in a high school right now and they're taking a test next door so I got to talk a little bit quietly so this microscope has the bulbs are down and they were kind enough to label that for us so the first thing you want to do is make sure it's unplugged in the back a lot of times I'll tell you what both you need this one needs a 12 volt 20 watt halogen bulb g4 style a lot of times on the bottom there's gonna be a access panel here you can use a flathead screwdriver or sometimes it's just finger loose so it open this door there's the bowl make sure it's not hot obviously it's not because it's dead take our new bulb and the important thing is to not touch the bulb because the oils from your fingers can decrease the life of the bulb so we're going to open it and just grab it by the packaging stick it in
