What was the revenue growth rate for the wireless connectivity products in the first quarter 
all over to Tyson.
Tyson Tuttle -- President and Chief Executive Officer
Thank you, John. We are pleased to report record first quarter revenue. The pandemic has led to an accelerated digital transformation creating market opportunities we've been able to seize through organic growth despite unprecedented global supply chain constraints. The revival of economic activity stemming from the recovery signals greater market growth ahead and we are well positioned to continue to capture share in 2021. Our opportunity pipeline continues to be robust at $15 billion and our design win lifetime revenue achievement in Q1 was up 8% year-on-year. Bookings have been very strong in recent months with the semiconductor industry poised to deliver an excellent 2021.
Turning to our IoT business. Wireless connectivity products continue to see surging momentum posting greater than 40% year-over-year growth in first quarter revenue. In Q1, we saw strength across our entire wireless portfolio with robust and consistent growth in all of our major wireless connectivity protocol. Security continues to be critical for the IoTs expansion and Silicon Labs has established a clear and unique leadership position in protecting IoT devices against bad actors.
In March, Silicon Labs became the world's first Silicon innovator to achieve PSA certified highest level of IoT hardware and software security. Our Secure Vault technology sets the standard for IoT security, effectively protecting against hardware and software attack. We've made strategic investments to ensure security as a core strength. Becoming the first company to achieve PSA level 3 certification is strong validation of our leadership role in securing the IoT.
In addition to delivering superior security in our high performance parts, we provide strong security in our battery optimized devices like the xG22, which just became the world's first wireless SoC to earn CCEF Level 3 Certification using the Diabetes Technology Society's DTSec security protection profile. DTSec sets the security standard for protecting personal and confidential healthcare data transmitted through connected devices.
In addition to becoming more secure the IoT is becoming more intelligent in areas such as motion detection, sound recognition, image classification and preventative maintenance. Developers innovating for these solutions faced obstacles and linking their machine learning models to real-world information. To help overcome these challenges, we have partnered with Edge Impulse to enable the integration of their tiny ML solution into our SoCs and MCUs. This is just one example of the ways that we are bringing the power of machine learning to developers of wireless edge devices.
Smart lighting continues to be a key growth driver for IoT business and we have a strong position in the lighting market, to enlarge part to our unique combination of best-in-class SoCs, and industry-leading portfolio. Our 15.4 mesh and bluetooth low energy products are deployed throughout the smart lighting industry, which is growing at a CAGR of 30%. A great example of this is our work with Yeelight, we recently launched a new smart LED light bulb with our BG21 Bluetooth SoC. This smart lighting products enables users to connect and control smart home devices directly from the Google Home app without the need for any other apps or software.
The exceptional user experiences our technology helps deliver are influencing the broader IoT ecosystem which will help more and more IoT products become mainstream. We are world leader in providing wireless connectivity solutions for the smart home, pushing the envelope to improve simplicity and ease of use. We recently collaborated with Allterco, to create the Shelly Motion, a new WiFi motion sensor with the world's lowest power consumption in mass production today.
Shelly Motion features up to 3-year battery life before recharging and is ideal for a wide range of motion sensing applications like lighting and security. Shelly Motion is another great example of our relentless focus on designing produc
