Klein Tools KHH56220 Hardhat Headlamp / Magnetic Work Light

The KHH56220 uses a bracket that attaches directly to Klein hard hats, so there is no strap and no zip-tying it to the shell. That is the trade-off to know before you order: it is built around the Klein hat brackets rather than a universal elastic band, so if your crew wears another maker's hat, plan on checking that bracket fit before you standardize a whole crew on it.

Three AAA cells, included in the box. Spotlight mode runs 6 hours at 150 lumens; floodlight drops to 50 lumens and stretches to 10 hours. For a full shift in a dark mechanical room or crawlspace, flood gets you through the day, spot does not. Carry a spare set of AAAs if you plan to work in spot the whole time.

Yes, the back is magnetic, so it sticks to a panel door, a strut channel, an enclosure, or the side of a ladder stabilizer and works as a hands-free work light. At 3.4 oz it is light enough to hold on painted steel without creeping. The 62 degree tilt lets you aim the beam down into a box or across a ceiling without moving the magnet.

The KHH56220 is rated for 6 foot (1.8 m) drop protection and is water and dust resistant, which covers the normal way one of these dies: knocked off a hat onto a slab, or left out in the rain on a site box. It is an ABS housing, not metal, so treat 6 feet as the design limit rather than an invitation.

It carries ETL and UL Listed marks, which is what a hospital, school district, or government MRO buyer usually needs on the paperwork before a tool goes on the approved list. That listing plus the LED source is the practical answer when someone asks whether it can be spec'd into a facility tool standard.

Operating range is 32 to 113 F (0 to 45 C), with storage from 14 to 131 F (-10 to 55 C). So a freezing loading dock at exactly 32 F is the bottom of what it is rated to run at, and a summer attic can easily exceed 113 F. It survives sitting in a cold truck overnight down to 14 F, but let it come up before you expect rated runtime.

Different jobs. Spotlight throws 150 lumens down a long run, a conduit chase, a trench, a corridor you are trying to see the far end of, and gives you 6 hours. Floodlight at 50 lumens washes the area right in front of you, which is what you want inside a panel, a junction box, or under a sink where a tight hot beam just blinds you off the metal, and it runs 10 hours. Most electricians live in flood and reach for spot when they need distance.

Small: 2.5 inches long, 2.25 inches high, 1.7 inches wide, and 3.4 oz. That is roughly a matchbox on the front of the brim, so it clears the top of a panel or a joist bay without catching. The weight matters more than the size for an all-day wear, and at 3.4 oz you are not fighting a front-heavy hat.

Klein Tools KHH56220 is the part number for the hardhat headlamp and magnetic work light. It is a single configuration, no finish or size choices to specify, and the 3 AAA cells come with it.
