Klein Tools 56040 – Frequently Asked Questions

1) Will the Klein 56040 flashlight hold on a steel panel or conduit for hands-free work?
Yes. The 56040 has a magnetic end cap, so it sticks to an electrical panel, enclosure, strut, or conduit and leaves both hands free. At 5.3 oz (151 g) and 5.98 inches long, there isn't much weight hanging off the magnet, so it holds on a vertical panel door without creeping. The aluminum body is 0.98 inch in diameter, so it also drops into a pocket or pouch between uses.
2) How long does the Klein 56040 rechargeable flashlight run on a charge?
Two settings, two very different runtimes. High is 350 lumens for 6 hours; low is 125 lumens for 12 hours. If you're pulling a full shift and want to charge once a day, run it on low and step up to high only for the panel work. A battery gauge warns you before it dies, and it recharges over micro-USB with the cable in the box, so nothing to buy and no cells to swap.
3) What is the red laser on the Klein 56040 flashlight actually for?
Pointing at things you can't reach. It's a Class IIIa red laser, 630 to 670 nm, 5 mW maximum, and the practical use is calling out a specific breaker, a conduit run overhead, a ceiling grid penetration, or a piece of equipment across a plant floor while you talk someone through it. It is a sighting and pointing laser, not a measuring or leveling tool, so if you need distance or a level line you want a laser distance meter or a line laser instead.
4) Can I use the Klein 56040 flashlight outdoors in the rain or in a dusty crawlspace?
IP54 rated, so it handles dust and water spray from any direction. That covers rain, a damp crawlspace, drywall dust, and a wet mechanical room. It is not submersible, so don't drop it in standing water and expect it to survive. Rated operating range is 32 to 104 F (0 to 40 C), which matters if you're working a job in freezing weather, the lithium-ion cell is not spec'd below freezing.
5) What comes in the box with the Klein 56040, and do I need to buy a charger?
You get the rechargeable flashlight and a micro-USB charging cable. No wall brick is included, so it charges off any USB port you already have, a truck adapter, a laptop, or a phone charger. There are no batteries to buy for it, the lithium-ion cell is built in.
6) Will the Klein 56040 survive being dropped off a ladder?
It's drop tested to 10 feet (3.04 m) with an aluminum body, so a fall from a step ladder or off a scaffold plank onto concrete is inside what it's built for. Combined with the IP54 rating, it's specified for jobsite handling rather than glovebox duty.
7) Does the Klein 56040 have a spot beam or a flood beam?
Both, you choose it on the fly. A twist focus bezel takes it from a concentrated spot for looking down a conduit run or into a deep junction box, out to a wide flood for lighting a work area or an attic. That's the difference between this and a fixed-beam light: one tool covers the tight inspection and the general area lighting instead of carrying two.
8) Is 350 lumens enough light for panel and troubleshooting work, or should I get something brighter?
350 lumens focused into a spot is plenty for panel interiors, junction boxes, device backs, and equipment nameplates, that's the work this is built around and the focus bezel concentrates all of it on a small target. Where 350 falls short is lighting a whole dark room or a large open bay, for that you want a work light or a stand light rather than a handheld. The 125 lumen low setting exists because full output is too much in a tight enclosure and it doubles your runtime to 12 hours.
9) Is the laser in the Klein 56040 compliant for use on a facility or government jobsite?
The laser is built to IEC 60825-1 and FDA requirements, which are the standards that govern laser product safety and classification. The tool also carries REACH, RoHS, CE-EMC, and CEC. If your facility's safety program requires laser classification documentation on hand tools, Class IIIa with a 5 mW maximum output is the figure to put on the paperwork.
10) Will the Klein 56040 clip to a shirt pocket or a tool pouch?
It has a removable pocket clip with a lanyard hole in it. Clip it to a shirt pocket or pouch edge, pull the clip off if you'd rather it ride loose in a bag, or run a lanyard through it when you're working aloft. The barrel is 0.98 inch in diameter and the light weighs 5.3 oz, so it isn't dragging a pocket down.
11) What size is the Klein 56040 flashlight, and will it fit in a standard tool pouch?
Overall it runs 5.98 inches long by 0.96 inch by 1.57 inches, with a 0.98 inch barrel diameter, so it drops into a standard flashlight loop or a pouch pocket without a fight. The 1.57 inch figure is the widest point, that's the head and the clip. Weight is 5.3 oz (151 g).
12) What is the Klein part number for the rechargeable focus flashlight with the red laser?
Klein Tools 56040. That's the number to give a purchasing department or to standardize on if you're buying these for a crew, one model, one charging cable type across the fleet.
