This "Lamsky BA15D Dual Contact LED Bulb Bayonet AC110-130V, 4W 6000K Daylight, 40W LED Halogen Replacement Bulb" replaced the 15W incandescent bulb in my Fantom handheld vacuum that blew out a long time ago. It's sold as a 40w replacement but as it only draws 4w that's a lot less than my 15w bulb so I ordered a 2 bulb kit for the price of a single bulb. The specs indicated the tension was fine, but I wasn't sure the diameter of the base - the part that fits in the vacuum - was correct. It was right there. And the light is brilliant - definitely no less than the 40 watt halogen equivalent. Even in a well-lit room, the light illuminates what is in front of the vacuum cleaner. Particles on my hardwood carpets literally bounced up in front of this light - and I thought the carpet was clean. I just cleaned the vacuum filters to get it working as best as possible. The superior light was the reason I could see the particles. I would give this lamp 10 stars if I could. And I have a second lightbulb if I ever need it. Not sure what "warmth" means, but the light from this bulb is bright white - perfect for a vacuum cleaner. However, make sure your app protects your eyes. The omnidirectional light from 51 LEDs is dazzling.
