LED Light Maintenance – 5 Tips for How to Maintain Your LED Lighting

LED Light Maintenance – 5 Tips for How to Maintain Your LED Lighting

On average, the lifetime of most LEDs is around 50,000 hours. It has even been estimated that LEDs could last up to 100,000 hours in the next five years. However, it doesn’t mean the light will last that long. Because the lifetime is also related with other components. That why it’s necessary for LED light maintenance. Do you want your LED lighting to work a long time? Here are some tips about how to maintain them.

Choose Appropriate LEDs

There are many choice for LEDs in the market. It’s important to invest in a quality product for that it can minimize the cost of maintenance. You also need to make sure the color temperature, lumen, color rendering index are what you want. The another thing you need notice, to inquiry about anything that can potentially damage the light or reduce its efficiency from the manufacturer.

Read User Manual before Use

Usually you can find the warning in the user manual. This part is what you should need to notice for it can decrease the trouble you may meet in the future. And don’t randomly disassemble the light without instruction. It may damage the circuit and have a bad influence on the lifetime.

Clean Them Regularly

Although LEDs greatly reduce a lot of money on led light maintenance, all lights, even LEDs, still need regular maintenance like clearance. The dust and debris of inside and outside could cause shortages. Units of the lighting need to be cleaned regularly. It’s helpful to extend the lifetime of use.

Avoid High Temperature and Humidity

The environment, including working temperature and storing temperature, is a very important factor in the lifetime of LED lights. Too hot or too wet environment will decrease the working time of lights for it will affect the electronic components inside.

Perform Inspections

Make sure that you perform occasional inspections on your LED lights. LED lights need to be used regularly for checking whether it is working well or not. If they are broken down, you will find it and repair them earlier.

Spotlights VS Floodlights

Spotlights VS Floodlights: What’s The Difference?

We created this resource to answer some frequently asked questions from customers about Spotlights VS Floodlights

What’s the difference between a spotlight and a floodlight?

What kind of beam spread do I need for my lighting project?

How can I know how wide my light bulb’s beam will be from a certain distance away?

First, Let’s Cover The Basics:

A spotlight casts a narrow beam of light, usually no wider than 45 degrees. This beam is more concentrated and easier to point and control.

A floodlight can have a beam spread of up to 120 degrees. It can illuminate a larger amount of space with the same wattage and lumen output as a spotlight.

Using Spotlights And Floodlights:


When highlighting specific points like display objects, wall artwork, architectural details, or landscape features, use a spotlight.

When illuminating larger areas like driveways, stages, warehouses, parking lots, or any other area that needs wide, even light coverage, go with a floodlight.

Determining Beam Width:

When planning your lighting scheme, knowing the width of a light’s beam in degrees isn’t always helpful. It would be much easier to know the beam width in feet, from a given distance away. Luckily, there’s a simple formula that can help you figure this out:

Angle of Beam x 0.018 x Distance from Light Bulb = Beam Width


So, if you have an 80 degree floodlight, and want to know how wide the beam will be from 10 feet away, just do the math:

80 degrees x 0.018 x 10 feet = 14.4 feet wide

If you have a 30 degree spotlight, and want to know how wide the beam will be from 15 feet away, here’s how you calculate it:

30 degrees x 0.018 x 15 feet = 8.1 feet wide

Caring for your camping gear: 5 tips on what to do

Your camping trip is over. It may have been a great trip, with good weather, delicious food and drinks, and plenty of memories. Or, you may have been miserable the entire trip. Either way, just because the trip is now over and you are home, it doesn’t mean that you should shove everything in the garage till next time. It’s tempting but not recommended. There are a few things we think all beginners to camping need to know about what to do when the camp trip is over.

Read these 5 easy tips to make your next camping trip a good one

1. Dry your camping gear
Sometimes you have to pack up the campsite and your shelter/gear is not fully dry. It may be because you had poor weather, or condensation.When you have to leave, you have to leave. Now that you are home, it’s time to dry all that gear out. If you have a small tent – you can hang it up inside the house to dry or over the clothesline (weather permitting).Only when it’s fully dry, will you put it all away.
Large tent/annexes – you may have to set the tent/annexe up in the yard to let it dry fully. This might mean that it could be up longer than a day, depending on the weather at home. But you want the shelters to be fully dry to stop mold and mildew forming. Camper Trailer canvas – let it dry out fully just like a tent. Any other gear that was damp – dry it out in the house or garage. Sleeping bags can hold a little moisture from your sweat during the night. It’s advisable to let them air as well inside the home (if you didn’t get an opportunity at the campsite in the morning).

2. Clean your camping gear
You may not want to do this first day back, but you should put this on your list for something to do pretty soon after the trip.It’s cleaning.I don’t mean laundry, because you probably already know that you have heaps of washing that has to be done.The below picture look familiar after a camping trip?
Look at the shelter you used (it may be obvious it needs a clean if it was wet and you are currently drying it somewhere). If so, you may want to clean your shelter using soapy warm water (not detergents), inside and out.
This isn’t very exciting to do, but when you next go in that shelter for your camping trip, you don’t want to open your shelter and find dirt inside and out of it. It’s going to make gear inside the shelter dirty before the trip has really begun.
Your food boxes and utensil boxes may also have suffered a little on the trip in terms of dirt.Heavy winds can get dust into these boxes even though you are pretty sure the lids were on tight. Check them out, and see if they need a quick clean.If you were doing fast wash ups (with minimal hot water and poor lighting) of your crockery and plates when camping, it may be a good idea to do a proper wash up when you get home. That means getting everything you used to eat on, out of the camping boxes and into the sink/dishwasher.Your future camper self will thank you for making this effort.
Any other gear you have taken – before you put it away, see if it needs attention. Sleeping bags, BBQs, lighting, stoves. All of this needs a quick investigation to see if it’s clean and ready for use the next trip.
With sleeping bags, special care is needed.
Esky/Fridge – however you kept your food cool, empty it entirely and clean out the fridge, with warm soapy water and dry thoroughly. Follow any manufacturer instructions to ensure it is maintained properly.You may be lucky, and find it all clean and ready to store.

3. Restock items (sooner rather than later)
We have learned this lesson the hard way. Run out of something at the campsite. eg. washing detergent, and you say to yourself “I must refill this when I get home”. But with all the other stuff going on, you just put your boxes away, and don’t check. Come next camping trip, you are missing something that is a staple of your camping trip. Suggest you go through your mandatory items that you take (this will vary but may be food items, firelighters, washing up gear, kitchen items like clingwrap or garbage bags), and make sure that you have enough packed for the next trip, before you put the boxes away.

4. Fix anything that didn’t work as it should have
Something didn’t work as it should on the camping trip? Stuck zippers? Broken pole? Faulty appliance? Canvas got a rip? Fix it whilst you remember. Before you put the gear away. Before you head out on your next trip, you don’t want to spend valuable time running around the place trying to get a spare part or solve the issue. This tip also includes batteries. If an item needed batteries and ran out – get them now. If you have been towing a camper trailer or caravan – attend to any mechanical repairs as soon as possible to prevent further damage to your vehicle.
Store your gear properly
If everything is clean and dry, how you treat your gear when not in use is going to be pretty important to how long it will last.Treat gear carefully (and kindly) and your camping gear will have a long life.
Sleeping bags
If you have down filled bags, you need to allow them to loft when not in use. That means not rolled up in a small stuff sack that you used for transport. Most down bags come with a bag to allow them to be stored, unrolled. This does take up space, but will keep your down filled sleeping bag in far better condition this way.
Synthetic bags are also meant to be stored this way, but due to space requirements we can’t do this – but it is recommended to help prevent damaging the fill.If you have the ability to hang your bag in a cupboard, then this is an option you can try.
Sleeping Mats
Like the sleeping bags, a sleeping mat is meant to be stored unrolled and flat, with air valves open, in a cool dark place.This is the ideal way BUT, it’s really hard to do. It’s going to depend on your space at home. Under the bed is a good place for them or standing up at the back of a large wardrobe. Don’t let your pets near them. Wipe them down with a damp cloth to also get off any dirt before it becomes too ingrained.
Most tents will be placed back in the bag they came with. Depending on the size of the tent, there is not a lot of options. Small backpacking tents can be stored in mesh bags/large cotton bags, out of sunlight.
Battery Operated Equipment
If you won’t be using your equipment for any long period of time, remove the batteries from the equipment (flashlights, headlamps, lanterns, GPS). You don’t need to throw the batteries away-store them in a plastic bag next to the equipment. That way if the batteries leak, they won’t be leaking inside your gear.
Cooking gear
Your gear is all clean (thanks to you doing tip 2 – see above) and there are no crumbs or grime on your gear. Store all gear in your clean camping boxes and make sure lids are on tight, so no bugs or rodents can get in.
Fridges when turned off (and after they have been cleaned thoroughly) may get a musty smell. To prevent this whilst you are storing, you can prop the fridge open a little to help get some air in it. This will reduce that smell. The same applies to your esky. Taking care of your gear after the trip is going to help make the next trip so much easier. It might not sound like it, but it all will help make your next camping holiday a little easier knowing that your gear is ready to go. Follow these tips each and every camping holiday conclusion and it will become just part of the camping experience.

led light bulbs

LED Light Bulbs Vs. CFL Light Bulbs: Which is Best for Me?

Before we had LEDs, there were compact fluorescent lamps, or CFLs for short. CFLs are fluorescent lamps that emit light from a mix of phosphors inside the bulb, and were designed to replace incandescent lamps (a lamp that produces light as a result of being heated). When compared to an incandescent bulb producing the same amount of light, CFLs use one-fifth to one-third the electric power, and last eight to fifteen times longer. Like all fluorescent lamps, CFLs contain toxic mercury, which complicates their disposal. In many countries, governments have established recycling schemes for CFLs and glass generally.

A light-emitting diode, or LED for short, is a lamp that emits light in a very narrow band of wavelengths. Because of this, LED’s are far more energy efficient than incandescent or fluorescent lights, which emit light in a much wider band of wavelengths. LED’s produce light that renders a color similar (but not identical) to natural daylight, which is measured on a scale called CRI, or Color Rendering Index. CRI’s range from 0-100, 100 being identical to natural daylight. Typical LED’s are around 70-95 CRI, but it is not recommended to put anything indoors below 75 CRI. Like incandescent lamps and unlike most fluorescent lamps, LEDs come to full brightness without need for a warm-up time.

So how much more efficient are LED’s? On average, an incandescent bulb may last around 1000 hours, while a fluorescent (CFL) bulb producing the same amount of light (in Lumens) may last around 8,000 hours, and an equivalent LED bulb may last around 25,000 hours. Because of their efficiency, LED’s are generally more costly, but the energy saved on your electric bill pays off when compared to incandescent bulbs.
