Fluorescents, LEDs go head-to-head: a comparison chart.
Lumens are the new unit of measurement for light bulbs. For decades, we’ve been buying light bulbs according to wattage. But as energy efficient, low-watt light bulbs like CFLs and LEDs have become readily available, watts have become an unreliable metric for selecting bulbs. Instead of focusing on wattage, which measures power or energy use.LED equivalent wattages to traditional light sources can only be approximate, as they will vary depending on the colour temperature and quality of the bulbs being compared. When comparing different light bulbs and lamps, it is better to compare the lumens that each bulb produces, in order to gain a true like-for-like comparison.Cost Comparison Equivalent Wattages and Light Output Comparing the Features Choosing an LED Light Bulb CFLs are a temporary solution to energy-efficient lighting, arriving on the market when first generation LED bulbs had a narrow and focused light beam and cost too much for many consumers.
LEDs are still the most expensive type of light bulb you'll see in the shops, but they do have advantages over the other types of bulbs. LEDs are the most energy-efficient bulbs. LEDs claim to be ultra long lasting - lasting for 25-30 years, depending on which one you buy and how you use it.You are assuming that each of these leds have perfectly identical IV curves. The stated specs are nominal, typical figures, and there will be variations. One LED may be 10mA at 1.9 VF, but another may be 8 or 12 mA or different at the same VF. That's not even taking brightness into account.
Power Consumption of RGB LED Strips. This guide will help you in estimating the power consumption of your LED setup. I’ve tried to keep it as straight forward and simple as possible on the one hand, but on the other hand didn’t want to limit it to only specific strips.
