Review: Bright (but not "4800LM"), work great - Bought these on a whim to compare them with the excellent DDM bulbs I've had in my Volvo backup lights for a little over 2 years now. Those have been an incredible improvement over the stock bulb, and I was hoping I might find something even brighter. Despite the ridiculous claim of 4800 lumens in the listing for these HSUN bulbs, they are still very bright and right on par with the DDM bulbs (listed as 800 lumens). However, these are a bit cheaper which is nice, and they seem to work just as good as the DDM. The bulb shell is pretty much identical between the two, only the LED chips are different, and since this bulb style is limited to 3.5w I suppose you can only get so many lumens/watt out of an LED. These are definitely worth purchasing and fit right into the original socket with no problems. Review: Great led bulbs. Let's see how long they last. - These bulbs are being used as turn signals and do not have hyperflash or bulb error codes on my 2010 Audi so far. They're also brighter than the old halogen bulbs. ## Features - Chip Type:Each 64136/BAY9S/H21W bulb includes 16 pieces High Power X B-D Chip,Beam Pattern:360 degree angle,Valtage: 12V-24V,Size:1.7(inch)/43.2(MM)*0.49(inch)/12.42(MM) - Extremely Bright: 4800LM High lumen Extremely bright white color lighting output,color temperature:6000K - Fit: BAY9S/H21W socket.It is the same socket as the BAY9S/H21W socket,you can use it with confidence if it is a [H21W] socket model of your car original halogen bulb - Easy to install: Built in Strong Canbus Function error free in 95% cars (High Power), just simply plug and play in 95% cars - pls check the original halogen bulb base/socket in your car before purchase. - Warranty:We offer 1 year free replacement warranty with Friendly customer service responses within 7*24 hour ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TMDBMVZ | | Auto Part Position | Center | | Best Sellers Rank | #155,297 in Automotive ( See Top 100 in Automotive ) #91 in Automotive Back Up Light Bulbs | | Brand | HSUN | | Brand Name | HSUN | | Color | White | | Color Temperature | 6000 Kelvin | | Customer Reviews | 4.0 out of 5 stars 90 Reviews | | Fit Type | Universal Fit | | Item Package Quantity | 1 | | Light Source Type | LED | | Manufacturer | HSUN | | Manufacturer Part Number | HSUN-001-BAY9S-021412 | | Number of Items | 2 | | Operating Life | 50000 hours | | Package Quantity | 1 | | Part Interchange Info | replacement | | UPC | 745610569270 745610569126 | | Unit Count | 2 Count | | Voltage | 24 volts | | Wattage | 21 watts | ## Product Details - **Brand:** HSUN - **Color Temperature:** 6000 Kelvin - **Item Package Quantity:** 1 - **Light Source Type:** LED - **Wattage:** 21 watts ## Images ![HSUN H21W BAY9S 64136 LED Bulbs,High Power X B-D Chipsets 4800LM Extremely Bright Bulbs with Canbus Error Free for Indicator, Backup Light and More,2 Pack,6000K White - Image 1](https://m.media-amazon.com/images/I/51rRSmP45cL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bright (but not "4800LM"), work great *by C***S on May 19, 2021* Bought these on a whim to compare them with the excellent DDM bulbs I've had in my Volvo backup lights for a little over 2 years now.
