Review: Great Kit, One Minor Deficiency, High Intensity Broad Spectrum UV-A - 2023-08-17 update: photos added after walls painted. Shorter wavelength UV delivers more energy and will cause fluorescent and phosphorescent paints to glow more brightly. These LEDs are 385 - 400 nM, compared to others that Only list 400 nM. They draw 12 watts per 20 feet, and come with a 24 watt power supply for a 40-foot strip (2 x 20-foot strips) with a power splitter cable. Yeah - I'm running 48 feet on one power supply (29 watts) - but all seems well. - The only detractor? The kit only includes 12 attachment clips for the entire 40 feet of LED strips. This is only one clip every 3.3 feet, not enough (and the sticky tape was NOT labled 3M). In my application, I needed a clip at both sides of the U-Turn, as well as the beginning and the end of the LED strip. Fortunately I had an accessory pack with extra clips - but this kit should have contained 20 clips. _ Not withstanding, still probably one of the best kits available. I used 2 of the 40-foot kits to run 6 x 12 foot lines (3 x 24 foot lines, 2 on one power supply, the third on the second). All lines are equally bright. Waiting for my artsy wife to add the UV flowers on the opposite wall. Will update when wall has been painted. Phosphorescent paints attached. My Score 86 rating. - Had I seen this, I might have saved 8 bucks (still not enough clips) and My Score 82 rating (4 less). https://www.desertcart.com/TigQiang-Flexible-Non-Waterproof-Fluorescent-Birthday/dp/B098DBK1T7 - My Score = 5* + 4* - 1* ## Features - Adjustable LED Strip: This 40ft LED strip light has 720 LEDs that can be adjusted to your desired length and cut without damaging the strip. - Easy Installation: The black light strip has an ON/OFF button and strong adhesive tape that makes it easy to install on walls and floors. - Safe to Use: The LED strip has a wavelength of 385-400nm that is harmless to humans and works with a 12V power supply. - Versatile Applications: This black light strip can be used for decoration, lighting projects, body paint, and more. It's perfect for Halloween parties, clubs, bars, and more. - Quality Guarantee: If you have any questions about the product, contact us within 24 hours for a prompt response. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0848RRB15 | | Additional Features | Linkable | | Best Sellers Rank | #36,887 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #60 in Black Light Fixtures | | Brand | YAYIT | | Brand Name | YAYIT | | Color | Black | | Color Temperature | 385 Kelvin | | Control Method | Touch | | Controller Type | Button Control | | Customer Reviews | 4.6 out of 5 stars 5,465 Reviews | | Form Factor | Strip | | Included Components | 2 x 6m / 20ft Black Lights Strip, 1 12V Power Adapter, 12 Fixing Clips | | Indoor Outdoor Usage | Indoor | | Indoor/Outdoor Usage | Indoor | | Item Length | 12 meters | | Item Type Name | nightlights | | Item Weight | 0.26 kg | | Light Color | Multicolor | | Light Source Type | LED | | Manufacturer | YYT | | Manufacturer Part Number | 40ft LED | | Manufacturer Warranty Description | 1 | | Material Type | Plastic | | Model Number | 40ft | | Number of Items | 1 | | Number of Light Sources | 720 | | Number of Packs | 2 | | Occasion | Congratulations | | Power Source | Corded Electric | | Product Style | Modern | | Special Feature | Linkable | | Theme | Music | | UPC | 781621106233 | | Unit Count | 1 Count | | Voltage | 12 volts_of_alternating_current | | Water Resistance Level | Not Water Resistant | | Wattage | 24 watts | | hanging_pattern_layout | Linear | ## Product Details - **Brand:** YAYIT - **Color:** Black - **Indoor/Outdoor Usage:** Indoor - **Light Color:** Multicolor - **Light Source Type:** LED - **Occasion:** Congratulations - **Power Source:** Corded Electric - **Special Feature:** Linkable - **Style:** Modern - **Theme:** Music ## Images ![40 Foot Led Black Light Strip Kit, 720 Units Led, 12V Flexible Blacklight Fixtures, Non-Waterproof - Image 1](https://m.media-amazon.com/images/I/81WRXClnHBL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is it two 20 foot pieces or one 40 foot?** A: A set of products is two 20ft. **Q: How long is the power cord?** A: Power adapter wire 4ft. **Q: Can you remove these after sticking them down and will they remove paint from a painted wall if stuck there and removed?** A: Since the double-sided adhesive on the back of the product has better adhesion, if it is stuck to a place where the paint is easy to fall off, the paint may fall off when removed. **Q: I purchased a set of these but need longer. Can I connect another strip to the red and black wires at the end?** A: Connecting a longer light strip will greatly reduce the brightness of the end of the light strip due to the problem of voltage drop. So we do not recommend you to do this. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive Illumination: YAYIT 40 Foot LED Black Light Strip Kit Review *by A***A on May 6, 2024* The YAYIT 40 Foot LED Black Light Strip Kit has impressed me with its exceptional illumination and versatility.
