Undoubtedly, LED lights are highly economical. Yet, they produce a great deal of bright light that can be really annoying at times. Especially, when it is your time to sleep, the dazzling LED lights surely not going to offer you a nice experience. Unfortunately, today’s technology hugely includes LED lights.

Many people complain about these LED lights on their alarm clocks, TVs, routers, and other electronic devices. People who require a full dark room to have a proper sleep cannot stand these lights. Hence, they intensively feel the urge to cover the LED lights instead.

But the question arises, is it safe to cover LED lights? Well, the answer is yes, covering LED lights are safe until you cover them with a proper manner and material. In fact, covering LED lights is a necessity since the blue lights of LED bulbs affect your health and potential sleeping hours.

Is It Safe to Cover LED Lights?

Absolutely! In fact, if your room is a shelter of too many electronic goods with LED lights, covering them is highly recommended. But you just cannot cover the LED lights with anything you want since the bulbs elevate higher temperatures. It certainly is safe and easy to operate the lights when they are covered.

But it may reduce the durability of the lights because of the elevated temperatures. Since the temperature does not get proper ventilation. So, it is a must to know what material are you going to use before coving the LED lights. Also, know the ways.

Why Is It Necessary to Cover LED Lights?

Well, as we have already mentioned the brightness of LED lights actually affects your health, it gets intense when you have to be around the lights 24/7. Apart from the disruption of sleep, the dazzling LEDs occur other health issues as well. It also discards one’s circadian rhythm.

However, the LED bulbs provide light according to the color temperature. Their color temperature can vary from 2200K to 6500K. The lowest color temperature delivers orange light that creates a reflection similar to candlelight.

Additionally, gradually when the color temperature arises, the bulbs increase the brightness of blue light. The blue light increases from 5000K to 6500K.

These LED bulbs are commercially provided as ‘Daylight’ bulbs. Moreover, new technology has introduced LED lights that come with fluorescent tube replacements. These bulbs tend to deliver more intensive blue light than other traditional fluorescent tubes.

That is why many prefer LED lights with a color temperature of 3000K. These led light deliver a warmer light. Nonetheless, still it is not enough since it will create disruption in your sleep.

Hence, the only way out of this problem is to cover the LED lights. Covering them creates a great deal of difference and actually fixes the problem. The worse effect will no longer haunt you once you cover them. So, it is not only necessary but also safe to cover LED lights.

8 Ways and Materials to Cover LED Light:

LED technology has surely been a blessing to this modern world. It has brought many advantages. But at the same time, they can be annoying depending on how and where they are used. Hence, to resist the dazzling lights, there are several ways to cover the LEDs. Let’s get to them.

1. Use Painted Tape:

Using painted tape to cover LED lights is a great idea. You can apply this trick on LEDs that are built-in on items like chargers, TVs, alarm clocks, routers, computers, speakers, and all.

Now, you can paint the tape using a black permanent marker or sharpie marker. You can also use black nail polish. The black color will resist the light to shine through the tape.

However, to make the tape fully opaque, use black nail polish instead. The permanent black marker may make the tape black but it won’t be fully opaque when the light passes by. Hence, to block the light properly using a black nail polish would be a better idea.

Now, just paint over the tape with black nail polish and cut it into small pieces so that it covers the small LED bulbs. Press the small pieces over the LED bulbs and let the tape stick properly. It won’t let the brightness of the LED light pass through.

This trick is easy and most importantly, removable. You can easily peel off the tape to make the lights visible again. It’s all up to your wish.

2. Opaque Adhesive Tape:

There are also some opaque adhesive tapes available in the market. You won’t have to color these tapes black with nail polish or marker. These opaque tapes are already colored and opaque enough to resist the light to go through them.

However, sometimes the residue of the adhesive tape can chip into the LED lights while peeling off. So, you should keep in knowledge about the fact while sticking painted or opaque adhesive tape to cover LED lights.

3. Dimming Stickers:

Light dimming stickers are also considered the best covers for LED lights. Dimming stickers are easily available in the market or any online shopping platform. These stickers mostly come in several sets.

Each set includes hundreds of dimming stickers of different sizes. They also come with several levels of opaqueness. You can select any of them according to your required opacity.

The most convincing thing about these dimming stickers is that they offer plenty of options to cover LED lights. Using these light dimming stickers is absolutely easy and safe as well.

Nonetheless, many use a dimmer to stop LED illuminants that are blinding. Though dimmer is not a covering material yet it can control the brightness of LED lights when attached to the switchboard. These LED dimmers are also on hype.

4. Diffuser Foil:

Installing diffuser foil is also a great idea to cover LED lights. Diffuser foils are mostly used to scatter the brightness of the LED lights. Most of the time, diffuser foil is attached in front of the light.

It creates a wide distribution of light. Therefore, the light source from the LED illuminant scatters and no longer reflects a bright appearance.

5. DIY Blackout Stickers:

There is also a DIY idea to solve this problem. You can make your own blackout stickers to cover LED lights. To make the blackout stickers you will need some materials.

They are wax papers, a hole punch, and a black color electrical tape. These materials are easily available in your home. That is why this is the simples DIY idea ever.

Now to make the stickers cut the black electrical tape into pieces and then place them on the wax paper. When the tape sticks onto the wax, press the hole punch on them.

This way, punch out some circles. Make sure to punch out from the taped areas only. That is how your DIY blackout stickers are prepared to slay over the LED lights.

To apply it over the lights, let the wax paper peeled off from the blackout circle stickers and expose their sticky part. Then set the dots over the LED lights to cover up fully.

This will completely block the lights. Using electrical tapes for this purpose is a blessing. You can easily remove these tapes whenever you want.

6. Lithographer’s Tape:

Apart from our discussed tapes, the Lithographer’s tape can also cover LED lights safely. Costing very little, this tape can be your life savior. With the red translucent Lithographer’s tape, you may not bring a long-lasting benefit yet it is helpful.

Moreover, this translucent tape almost works like the LED-dimming stickers. However, the tape delivers a little reddish tint after covering the LED light bulbs. But it is okay until it is unsafe.

7. Frosted Scotch Tape:

Another Scotch tape is another way to cover LED lights. To speak of the frosted scotch tape, mostly it is known and used as semi-frosted office tape.

However, using this tape won’t fully cover the LED lights still it can be a good source until you get anything else to cover them. To have the quickest fixation of the LEDs of your room, you can give a thought about this frosted scotch tape.

8. Barrier Materials:

There are some barrier materials available that are used for covering the LED lights. These materials are mainly used for diffusing purpose. They cover the lights and diffuse brightness. Some of the materials are given below.

a) Aluminum Opaque Extrusions:

Aluminum LED strip extrusions are great barrier materials for covering LED lights. You can get these strip extrusions at any local hardware store. One is flat and the other is curved. Moreover, the depth of the strips ranges from 10mm to 17mm.

Nonetheless, to get a better cover choose the curved aluminum strip extrusions with higher screens. Because the lower flat extrusions do not offer much diffusion hence the covering of LED lights also becomes meaningless.

b) Fabrics:

To cover the decorative LED lights or ceiling lights, fabrics are surely a great help. Nonetheless, among many types of fabrics, the most suitable are woven fabrics. These fabrics tend to be non-stretchy and flat. That is why covering LED lights with these fabrics is safe and an absolutely great idea.

Whereas the paper can be a temporary coverer, these fabrics will offer long-lasting service. Moreover, there are other types of fabrics that are also used the LED lights coverers. They are knit fabrics. According to their knitting, these fabrics provide service.

c) Other Adhesives and Glue:

Glue also works as an adhesive to cover LED lights. Using glue makes a huge difference. However, there is transparent glue available as well. It can be used as a great LED light diffuser. Just apply the glue over the light bulbs and let them dry. After it solidifies, the glue will cover it all.

d) Thermoplastic:

Many people also use thermoplastic to cover LEDs. Thermoplastics are not fully opaque yet they come in versatile colors and sizes. So, you can choose any color and size according to your need.

e) Epoxy:

To cover LED lights with low voltage, epoxy material is also used. Applying epoxy over the LEDs makes a great cover. However, higher voltage LEDs tend to get hotter when epoxy is applied over them. This heat gradually shortens the life of the LED lights. So, it is recommended to apply only over the low voltage LEDs.

Final Verdict:

Now you know if it is safe to cover LED lights or not. Covering LED lights is actually fun. This is mainly a DIY job. nonetheless, it would be unwise if you cover it with just anything. Therefore, our suggested materials and ways are recommended to you.

However, some of these materials cover the LEDs and block the lights fully and some create a dimmed or diffused light. So, you can go for any of the solutions that will meet your need.
