Browse the aisles or webpage of almost any home improvement or lighting shop and you will find an overwhelming array of corded LED lighting solutions. Each maker makes bold claims about durability and brightness, but will the claims be reliable? And what’s more, can you determine which product will live up to your expectations BEFORE you put your money on the counter? Below are some quick and easy tips for preventing buyer’s guilt on the following battery light buy. A number of these tips apply primarily to white LEDs and rechargeable batteries, the most common bulb and battery type in these goods, but you need to be able to use the general principles to nearly any battery light product.
1. Know what you need. Small batteries mean small, portable products, however if portability is the key concern the product ought to be one you utilize intermittently or you will need to accept shorter battery life. Should you require long battery life in a product which gets lots of use, look for a product using a bigger battery dimensions; basically a bigger gas tank. As a general rule, each step up in battery dimensions, triple-A to double-A etc, slightly more than doubles battery capability. If you require high light output and a very long battery life, start looking for products using a greater number of larger batteries. Understanding your priorities can help you decide what tradeoffs you are willing to create.
2. Compare the amount of LEDs and also the quantity and size of batteries within your prospective purchase. The higher the total battery volume to LED ratio, the brighter it’s likely to be and more it is likely to last. Whatever the marketing states, six triple-A batteries will not drive a twelve LED lighting bar for quite long with all types of brightness.
3. Bigger batteries are better than more batteries. For example 3 double-A batteries would be more preferable to 7 triple-A’s even though the theoretical capacity is almost identical.
4. High quality LED products should have at least three individual batteries. Regardless of their capacity, triple-A’s, double-A’s, C’s, and D’s most provide 1.5 volts initially, slowly dropping to.9 volts over the life span of the battery life. For maximum brightness white, green, or blue LEDs need 3 to 4.5 volts. This means that an LED running on a single battery needs a unique circuit to increase the voltage. Unfortunately, using one battery to do the job of three naturally reduced battery lifetime by two-thirds. So unless small size is a high priority, start looking for three or more batteries and you’ll find these 3 volts from begin to finish.
5. LEDs and 9-volt batteries don’t mix. While there are ways around it if small size is a priority, for the most part 9-volt batteries aren’t well suited to LED applications. Even if the product designer has put in the correct attempt to match the demands of the LED into the output of this 20700 Battery , 9-volt batteries have significantly less capacity compared to a double-A battery of the same chemistry.
6. Do not get taken in by peak operation. Batteries really function marginally 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 slightly 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 with no battery life claims or exceptionally high claims without rationale. It must raise a red flag when the item does not make any claims about battery life. Fantastic battery life is an integral selling point, and whether the product does not make any claim it could be concealing something. On the reverse side, if the item claims an extremely long battery life ensure that the product has a fantastic number of large batteries to back this up. Otherwise the item must be operating in a lower light level (that you may decide is acceptable for your application) or it had been quantified past the stage where many users would consider the batteries dead.
8. Don’t assume a high wattage LED is really running at full power. Though this might change under new labeling regulations, there’s presently no promise that a product advertising high watt LEDs is really supplying maximum brightness by providing them with full power. Unfortunately there is no way depending on the packaging to assess whether or not the product really puts the maximum wattage through each LED. Just keep in mind that the wattage rating of this LED is not a brightness case.
9. Maintain realistic expectations. As much as we might wish otherwise, batteries and LEDs doesn’t equal magical. There has to be a balance between light output, battery capacity, and battery life. If you’d like bright light or long battery life you’ll need a large battery size and count. There’s simply no way to beat the mathematics.
