Many LED PAR38 lamps are brighter, which is great for accent lighting. If you're looking for a lower-output PAR38, you may need to consider a different shape (like a PAR20) or a compatible dimmer. LED equivalents to metal halide lighting offer similar energy savings as over sodium lighting – around 50%. Metal Halide Light Bulb Wattage

As you can see, there are many benefits of LED bulbs over HID bulbs, traditional incandescent light bulbs, metal halides and High Pressure Sodium. He said: “LEDs use less energy and cost you a lot less in the long run. There is not a huge difference in price, they last longer so you won’t need to keep buying replacements. It makes complete sense to buy LED bulbs.” You may be more familiar with light bulbs being measured by their wattage, with watts being the primary unit of measurement for standard light bulbs. However, many manufacturers are now stepping away from wattage, which measures the power of a light bulb, and instead label their bulbs by lumens. Lumens are an accurate measurement of brightness, and all energy efficient light bulbs, such as LED light bulbs, are now labelled by lumens accordingly. I'd say it's wider than your area but probably slightly shorter at a guess. Actually it might be about 15m long thereabouts but the width of the garden, and i'm guessing again, could be 20-30mtrs. LEDs were designed to be more energy efficient, which means they have a lower wattage for a similar light output. Wattage used to be the main factor in brightness. The higher the wattage, the more light would be emitted from the bulb. Now, LEDs have lower wattages to save energy, so it's no longer a good determination of light levels.

Lighting terms to guide your LED purchase

CFL (compact fluorescent lamp) light bulbs were the first real energy-efficient alternative to incandescent and halogen bulbs, using much less energy and lasting for much longer. LED light bulbs take energy efficiency to another level, using around 40% less energy than CFL equivalents. CFL Light Bulb Wattage

An LED under similar conditions lasts 10,000 hours upwards, for 10 years or longer. Saving money with LED bulbs At this point, it’s important to note that if it is a halogen transformer,this maximum load applies to halogen light bulbs only. For example, if you have a 40VA transformer for halogen bulbs, you should not install 40-watts worth of LED light bulbs. This would overload the fitting and potentially cause a safety issue. Bulbs that operate on a lower voltage than 230-240V must be used with a compatible transformer when installing on UK mains circuits. The transformer converts mains voltage to a lower voltage suitable for the bulbs, ensuring they function as designed and preventing damage to the bulbs and/or light fittings. Yet it is the versatile LED bulb that is leading the way in efficiency, durability and versatility, too. Why buying LED bulbs makes senseNatWest, Royal Bank of Scotland (RBS) and Ulster Bank, which are all part of the NatWest Group, will now shut at least 172 of their bank branches in 2023 and 2024.
