COOSPIDER - I purchased my first Coospider UVC lamp (w/ozone) 1-1/2 years ago for $16 and it is still working. Of course the usage has gone up since the virus. I bought it to remove the dog odors from my room and it worked great (w/ozone). Now the prices have gone up 3 fold just because of demand I'm sure. I bought a generic one and it failed after maybe 72 hours of use. Coospider has put their name on their product and states an 8000 hour warranty that's about a year of 24 hours a day use. I recommend using a fine tip sharpie and putting the date you received it on the base just in case it fails. I just ordered a second (no ozone) one a few minutes ago. I put one at the bottom of the stairs. I have roommates upstairs so I'm hoping this will be a virus curtain to keep anything they drag home away from me. And I already bought a second (W/ozone) because I loaned the first one to my chiropractor and he won't give it back. Get an off delay timer to use with the ozone model as you don't want to enter the room until the ozone has cleared (bad for living things) like this one BN-LINK [2020 New Version] Smart Digital Countdown Timer with Repeat Function. Review: Works well, no need to buy base, screws into a regular lamp base. - Purchased prior to virus outbreak this year for a mold problem from leaking roof. Easy to use in my large home. You can smell the UVC worked so it is easy to feel confident bacteria is killed. I now use it to disinfect the heaviest use rooms. Make sure you have the yellow UV wrap around protective glasses to keep your eyes from injury. (Mine were previously purchased for use at a rifle range & outdoor construction.) No need to buy a base. Use a table lamp turned on with extension cord in separate room. Close door, then plug safely into an outlet in the other room you are that is not being cleaned. Unplug when time is up. ## Features - 【Size】 Tube Diameter 1 inch (2.54cm); Full length (include pins): 18 inch (45.7cm); Base:G13, 4-pin Double-ended.【please measure and confirm the bulb size is fit before placing order】 - 【 365 368nm wavelength】For better performance, we suggest ro replace bulbs every 4-5 months. - 【 Warm Tips 】When replace the bulbs: Pay Attention to the machine remaining-high-voltage-electric shock, use a screwdriver or scissors to touch the grid to discharg at first. - 【 WARRANTY 】 We provide high quality bulb, 8000hours warranty. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KYVRVX7 | | Accepted voltage frequency | 100 to 120 Volts and 60 Hertz | | Average Life | 8000 Hours | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #1,822,492 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3,770 in Compact Fluorescent Bulbs | | Brand | COOSPIDER | | Bulb Base | G13 | | Bulb Shape Size | T | | Color | 15w-1-packs | | Color Rendering Index | 80 | | Control Method | Push Button | | Customer Reviews | 4.3 4.3 out of 5 stars (1,067) | | Date First Available | November 29, 2018 | | Indoor/Outdoor Usage | Indoor | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 5.1 ounces | | Item model number | 25wE26 | | Light Color | Blue | | Light Source Type | CFL | | Light Source Wattage | 15 Watts | | Light Type | Fluorescent | | Manufacturer | Coospider | | Material | Glass | | Model Name | 15W-1PCS | | Number of Items | 1 | | Part Number | 25wE26 | | Power Consumption | 25 Watts | | Power Source | Corded Electric | | Product Dimensions | 8.5 x 2 x 2 inches | | Shape | Globe(G) | | Size | 1 Count (Pack of 1) | | Special Feature | Long Lasting | | Special Features | Long Lasting | | Specific Uses For Product | Lamp | | UPC | 656699838198 | | Unit Count | 1 Count | | Voltage | 110 Volts | | Wattage | 15 watts | ## Product Details - **Brand:** COOSPIDER - **Bulb Shape Size:** T - **Light Type:** Fluorescent - **Special Feature:** Long Lasting - **Wattage:** 15 watts ## Images ![COOSPIDER 15W U/V BL CFL Compact Light Bulb for 30W Electric Zapper Replacement Straight Tube T8 F15 18 Inch Blue Light - Image 1](https://m.media-amazon.com/images/I/415z6Vr4UtL.jpg) ![COOSPIDER 15W U/V BL CFL Compact Light Bulb for 30W Electric Zapper Replacement Straight Tube T8 F15 18 Inch Blue Light - Image 2](https://m.media-amazon.com/images/I/41sU3NtmcFL.jpg) ![COOSPIDER 15W U/V BL CFL Compact Light Bulb for 30W Electric Zapper Replacement Straight Tube T8 F15 18 Inch Blue Light - Image 3](https://m.media-amazon.com/images/I/51egUqE8crL.jpg) ![COOSPIDER 15W U/V BL CFL Compact Light Bulb for 30W Electric Zapper Replacement Straight Tube T8 F15 18 Inch Blue Light - Image 4](https://m.media-amazon.com/images/I/51znN34LqHL.jpg) ![COOSPIDER 15W U/V BL CFL Compact Light Bulb for 30W Electric Zapper Replacement Straight Tube T8 F15 18 Inch Blue Light - Image 5](https://m.media-amazon.com/images/I/61ro2xgrSJL.jpg) ## Questions & Answers **Q: does it penetrate obstacles like wood and plastic? I mean, does it sanitize behind the tables, big cups and kitchenware?** A: No, the UVC light only can sanitizer the objects which exposed to its light. it can't penetrate the obstacles **Q: can i use this in a mechanic's trouble light fixture to sanitize objects by hand?** A: If your trouble light has an E26 or E27 (common in the US) base (socket) it will fit. It will protrude 7 and 1/2 inches so if your trouble light has a cowling make sure you have enough space to insert and tighten the bulb (8 or 8 1/2"? ) If you plan to sanitize by hand, protect your ski and eyes. The light may not seem very bright but that's because we don't see in that spectrum. **Q: Any proof this item actually works/is effective?** A: UVC and OZONE are some of the best ways to sterilize "things". Both of these lamp options (Ozone and Ozone free) both produce Ozone. They are made in China. You get what you pay for. If you want a 100% surefire way these will work, you must go the T8/T12 tube lamp route. They will work in your common fluorescent fixtures, but they will burn out in short order as they somewhat NEED a more specific ballast which is more costly than a regular ballast that would come in a regular fluorescent fixture. **Q: It is advertised as uv-c, but the bulb states only uv which is it?** A: UV bulb is a general term for ultraviolet light bulbs, UV bulbs can be divided into many types depending on the wavelength, UVC: 100--280nm, UVB: 290--320nm, UVA: 320--400nm, the wavelength of this bulb is 254nm, so it is UV-C bulb, UV-C bulb can use to kill bacterial virus dust mites. ## Customer Reviews ### ⭐⭐⭐⭐⭐ When they put their name on the product it means something.
