The helmet decision: coverage, eye protection, or lights
You need a helmet that fits your head size, your riding style, and the conditions you ride in. The four adult helmets here span a wide price range, from a simple road/MTB shell to a commuter helmet with more equipment. Some riders only need a lightweight shell for weekend rides; others want a helmet that includes extra equipment so they don't have to buy it separately. A third group needs visibility for street riding, and one of these helmets is designed specifically around that.
Quick take
The four helmets here split into three use cases: two PJT models, an ultralight road/MTB shell, and an ILM commuter helmet with built-in lights. Your first move is to decide whether you want extra equipment on the helmet or a simpler shell. The price spread means there is room for both a budget-oriented build and a feature-heavy build in the same comparison.

Product notes
PJT Lightweight Cycling Helmet Magnetic Goggles Lens Adult Bike Helmet 56-61cm (12 Black-White-Gray)
The PJT helmet is a half-helmet design for adults, with 16-20 air vents and a 56-61cm head-size range. A magnetic-attraction goggle lens lets you switch the lens without removing the helmet. The shell combines a PC outer layer with EPS material, and the colorway is 12 Black-White-Gray. Choose it if you want a lower-priced helmet that includes integrated eye protection rather than a separate pair of glasses. The one-size 56-61cm fit is the main constraint, so it is not aimed at larger head sizes. If your head falls inside that range, this is the simplest way to get a goggle lens as part of the helmet itself.
PJT Lightweight Cycling Helmet Magnetic Goggles Lens Adult Bike Helmet 56-61cm (Carbon Fiber-B-T)
This is the second PJT helmet in the comparison, with the color changed to Carbon Fiber-B-T. Like the other PJT, it is a half-helmet design for adults with a one-size 56-61cm fit, and it shares the same shell approach. The visible difference is the finish: Carbon Fiber-B-T instead of 12 Black-White-Gray. Choose it if you prefer the darker carbon-fiber look and want to stay in the same PJT helmet family. The fixed 56-61cm fit range is the limitation, meaning it targets average adult head sizes rather than very large or very small heads. For riders who like the PJT feature set but want a different visual tone, this is the version to compare.
Ultralight Adult Bike Helmet Road MTB Cycling Helmet White Dark Blue
This helmet is aimed at road cycling and mountain biking, with a white and dark blue finish. It uses a PC shell with EPS foam and weighs approximately 205g, making it the lightest of the four helmets by listed weight. It is marked as size L and fits 57-62cm, the largest head-size range here. Choose it when you want a simple, low-weight shell and need a bit more room at the top end of the fit range. The trade-off is that the fit starts at 57cm, so it is not designed for heads below that threshold.
ILM Bike Cycling Helmet with USB Rechargeable LED Front and Back Light Men Women
The ILM helmet is a unisex adult model in Matte Black with a detachable tinted lens. It has a USB rechargeable front and back light with four lighting modes and 10 vents for airflow. The helmet is eyeglass-friendly, and the lining uses a breathable mesh fabric to keep you dry. It is the only helmet in the group with a built-in rechargeable light system, making it a natural option for commuters who want visibility without a separate light mount. The item weight is 0.8 lbs, so it is not the lightest option here. If you ride in traffic or at dusk, the front and rear light setup is the clear reason to look at this one.
Final recommendation
Here's how the choice breaks down by use case. For the lowest listed price, the PJT in 12 Black-White-Gray at USD 18.48 is the straightforward pick. If you need a larger fit band, the Ultralight Adult Bike Helmet at USD 18.99 covers 57-62cm. For a visibility-focused setup, the ILM at USD 69.99 brings a USB rechargeable light system and a detachable tinted lens. Between the two PJT colorways, the Carbon Fiber-B-T version at USD 27.97 exists for riders who want that darker finish at a middle price point.
