Nice light bulbs!

Cool! The reason why those bulbs are rated for 130V is so that when you power them with 120V, they aren't at full capacity making them last longer.

3:52 They do make those MR16s in 120V. They have GU10 bases instead of GU5.3. 4:18 There is some sort of relationship between bulb shape and the amount of light it gives off for a given wattage. I’m not sure why, but you’ll notice that specialty bulbs are typically dimmer than regular A19 bulbs. So an A19 40W bulb might be 450 lumens and the A15 and B10 bulbs like you showed were 375 and 350 respectively. 5:00 NSP stands for narrow spot 5:38 Wow, that halogen bulb must not be modified spectrum, since it doesn’t have a reduced lumen output. Notice how the GE ones at 7:01 have a reduced lumen output, they have a coating that modifies the light spectrum they emit to make it warmer. First time I’ve seen a Sylvania non-modified spectrum one in the A19 shape. 7:31 Nope, at least not for the US market. They were banned from first-hand sale in the US not too long ago. 11:58 Wow, those are some very late 60W incandescent bulbs if they have the lighting facts on them. That was introduced in 2011, and 60W incandescent bulbs were banned from sale in 2014.

4:18 This could be because not as much light can pass through the frosting.
