Description
Headlamp HF4R Core is a slim, extremely lightweight basic headlamp for everyday use. For dog walking, camping or routine tasks it provides optimal near- and far-field illumination via two light sources, plus a red front light when reduced glare is preferred. The continuously pivotable lamp head adds aiming flexibility, while the individually adjustable narrow headband keeps the unit secure and comfortable on the head. An integrated rechargeable battery recharges simply and quickly through the Magnetic Charge System. Practical extras include a transport lock and clear battery and charge-level indicators, so readiness is easy to check before work. Supplied as a single piece from manufacturer Rettberg, this Ledlenser HF4R Core model suits laboratory, workshop and field settings that need reliable hands-free lighting without bulk. Dual light sources support clear visibility at different distances, and the compact form factor keeps weight low for extended wear during inspections, sampling or outdoor preparation.

Questions about Headlamp HF4R Core
What is this article?
Headlamp HF4R Core is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Cold light sources & lighting, inside Microscopy & histology, in Lab instruments.
A cold light keeps the heat of the lamp away from a living or a melting specimen, usually by a fibre light guide. It is the illuminator for a stereo microscope. Colour temperature matters when the image is photographed. A hot lamp over a dissection dries the sample.
A light microscope forms an image with glass lenses and transmitted or reflected light. A stereo microscope is the lower-magnification instrument for dissecting and for looking at a surface. Fluorescence needs a light source and filters matched to the dye. Histology is the preparation that makes a tissue readable: fixation, a cassette, a section, a stain. The objective's magnification and numerical aperture decide the resolution. The slide and the cover glass decide whether the section sits in the focal plane. Stains and dyes as substances are identified on PubChem. Papers on the methods are on PubMed.
