Frequently asked questions

Is this a genuine product with a valid warranty?

Yes. We are an authorized dealer for Klarus and TrustFire, so every light we ship is genuine and carries the full manufacturer warranty, handled by us. Flashlights bought through unauthorized or grey-market sellers are usually not covered.

How fast do you ship, and what does it cost?

Orders placed on business days leave our Port Charlotte, Florida warehouse within 24 hours. Shipping is free on US orders over $49. We hold our own stock, so if the site shows it in stock, it is on a shelf here.

What is your return policy?

Returns are accepted within 30 days through a simple return process. See our refund policy for full details, or email us first if you are unsure whether a light is the right one and we will help you decide before you buy.

How many lumens do I actually need?

More than most people expect to hear: usually fewer than you think. 200 to 500 lumens covers everyday tasks, 500 to 1,500 covers work and duty use, and above that you are buying reach rather than usable working light. Runtime drops sharply at maximum output on every light ever made.

What is the difference between lumens and beam distance?

Lumens measure total light output. Candela measures beam intensity, and that is what determines how far a light throws. A tightly focused 1,000-lumen thrower will out-distance a 3,000-lumen floodlight, which is why reflector design matters as much as the headline number.

Which battery does it take, and do you sell spares?

Most of our lights use a built-in or removable lithium-ion cell such as a 14500, 16340, 18650, 21700 or 26650. The size is listed in the product specifications. We stock protected cells in all of those sizes plus a multi-chemistry charger, so you can keep a charged spare ready.

Can you help me choose between two models?

Yes, and we would rather do that than have you return something. Email Customersupport@brightlightled.shop or call 941-273-3209, Monday to Friday 8am to 5pm EST, with the two models and how you plan to use the light.
