The Gemini Lights IRIS Rear Light 180L is one of the most affordable and high-performing rear lights on the market. Pumping out an impressive 180 lumens, this light has a running time of between 1 - 12 hours, ensuring that if you do forget to charge it, you’ll still have enough juice to get you home. Full recharge is even possible in just 90 minutes, meaning that you can charge it at work via a USB cord!

Gemini Lights IRIS Rear Light 180L

The Gemini Lights IRIS Rear Light 180L is a great choice for any rider looking to enhance their visibility and safety in low-light conditions. Providing 180 lumens of power, 10 different levels of beam and a run time of between 1 - 22 hours, the IRIS might be the best rear light out on the market at this price point.

Gemini Lights describe the IRIS as a confidence booster, and we wholeheartedly agree. When you’re out on the bike and worrying about whether a motorist can see you, you take it easier and tend to take your ride a lot more cautiously, but with a light so functional and performance friendly as the IRIS, you can be safe in the knowledge you’re seen from afar.

Weighing just 42g, you know this light isn’t going to affect your efficiency or aerodynamics. The subtle rubberised strap fits around most seatposts or using the clip mount, you can attach it to your saddlebag if it has the necessary clip.

Four modes including low flash, high flash, low pulse and high pulse are also all evident within the IRIS, whilst the hard anodised aluminium construction has been used to enhance durability, ensuring this light stands the test of time.

When you’re running low on power, simply connect it to your laptop via the handy USB cord provided in the pack and after 90 minutes of charge, it’s ready to go with full battery.
