9 Ways to Avoid Getting Ripped Off on Battery Lighting


Read the aisles or page of almost any home improvement or lighting shop and you will find an overwhelming array of battery-powered LED lighting solutions. Each maker makes bold claims regarding durability and brightness, but will the claims be trusted? And more importantly, can you identify which product will fulfill your expectations BEFORE you place your money on the counter? Here are some quick and easy tips for preventing buyer’s remorse on your next battery light purchase. A number of these tips apply primarily to white LEDs and rechargeable batteries, the most frequent battery and bulb kind in these goods, but you need to be able to use the general principles to nearly any battery lighting product.

1. Know what you need. Little batteries imply small, mobile products, but if portability is the key concern the product ought to be one you use intermittently or you’ll have to accept shorter battery life. If you require long battery life in a item which gets a lot of use, start looking for a product using a bigger battery size; essentially a bigger gas tank. As a general rule, each step up in battery size, triple-A to double-A etc, slightly more than doubles battery capability. If you require high light output and a long battery life, look for products with a greater number of larger batteries. Knowing your priorities will help you decide what tradeoffs you’re willing to make.

2. Compare the number of LEDs and also the number and size of batteries within your prospective purchase. The higher the total battery quantity to LED ratio, the brighter it is likely to be and more it’s very likely to last. Regardless of what the marketing states, six triple-A batteries will not induce a twelve LED light bar for very long with all types of brightness.

3. For example 3 double-A batteries are preferable to 7 triple-A’s although the theoretical capacity is nearly identical.

4. High quality LED products should have at least three batteries. Regardless of their capability, triple-A’s, double-A’s, C’s, and D’s all supply 1.5 volts originally, gradually dropping to.9 volts over the life of the battery life. This means an LED running on a single battery needs a unique circuit to increase the voltage. Therefore unless small size is a top priority, start looking for three or batteries and you’re going to get these 3 volts from begin to finish.

5. LEDs and 9-volt batteries don’t mix. When there are ways around it if small size is a priority, for the large part 9-volt batteries are not well suited for LED applications. Even if the product designer has put in the proper attempt to coordinate with the requirements of the LED into the output of this battery, 9-volt batteries have less capacity than the usual double-A battery of the same chemistry.

6. Don’t get taken in by peak operation. Batteries really operate slightly above their top rated functionality for the first few hours. It depends somewhat on the product, but you should expect the in-store presentation or the fresh-from-the-box functionality to be somewhat brighter than your normal encounter as the batteries output decreases over time. If the first brightness just just meets your requirements, it may disappoint you down the line.

7. Beware of products without a Samsung 40T 21700 battery life claims or extremely substantial claims without justification. It should raise a red flag when the product doesn’t make any claims about battery life. Good battery life is a key selling point, and whether the product does not make any claim it may be hiding something. On the reverse side, if the item claims an extremely long battery life make sure that the product has a good number of large batteries to back this up. Otherwise the product must be operating at a lower light level (that you may decide is acceptable for your application) or it was quantified past the point where many users would consider the batteries dead.

8. Don’t presume a high wattage LED is really running at full power. While this may change under new labeling regulations, there’s presently no guarantee that a product advertisements high watt LEDs is actually providing maximum brightness by providing them with complete power. Unfortunately there’s no way based on the packaging to assess whether the item actually puts the most wattage through each LED. Just keep in mind the wattage rating of the LED is not a brightness case.

9. As much as we may wish otherwise, batteries and LEDs doesn’t equal magic. If you want bright light and/or long battery life you’ll need a large battery count and size. There is just no way to win against the math.
