Yes, you can use a Sharpie on a light bulb. The ink will stay on the glass and will not come off.
An excitation filter is a filter used in fluorescence microscopy to selectively pass light of a particular wavelength range to the specimen, while blocking the emission spectrum of the fluorophores used to label the specimen. The purpose of the excitation filter is to allow only light of the correct wavelength to reach the fluorophores, so that they can be excited and emit light that can be observed and imaged.
A filter is a device that is used to separate substances from a mixture. Filters work by letting some substances pass through them while blocking others. The substances that are able to pass through the filter are called the filtrate. The substances that are blocked by the filter are called the residue. Filters can be made out of a variety of materials, including paper, cloth, metal, and plastic. The type of material that is used to make a filter will determine what substances it can block. For example, a filter made out of cloth can be used to remove large particles
There are a few ways to tell if your LED lights are full spectrum. One way is to look at the color of the light. Full spectrum LED lights will emit a white light, while other types of LED lights will emit a yellow light. Another way to tell if your LED lights are full spectrum is to look at the price. Full spectrum LED lights are typically more expensive than other types of LED lights.

Gels work well. Color theory is a body of knowledge that provides practical advice for color mixing and the visual effects of a particular color combination in the visual arts. The main color, secondary color, and tertiary color are additional classifications of colors based on the color wheel.You can utilize these gels as main, secondary, or tertiary materials.We can also deceive the camera. I occasionally use CTO gel (color temperature orange) and set the camera's white balance to 3200k (or, depending on the lighting conditions, near to fluorescent). At a 45 degree angle, the subject's nose will be struck by the CTO flash. Because of CTO, this typically results in a blue background with the original skin tone.There are many methods available. The skin tone does not change when the color temperature is kept at 10000k (or close to tungsten depending on the lighting and environment) and CTB color temp blue.Since this package includes a variety of gels, we can experiment with many different colors. Another tactic I do is to apply a green gel to my Godox flash with a zoom of 20mm and a power of 1/64 when there are a lot of trees and plants in the background. Because of the Gel, the vegetation appears significantly greener to the sight.Absolutely worth the cost.Users' experiences could be better. Two minutes are needed to remove one gel and keep another. If you need to adjust your flash positions, camera settings, or flash gels while the session is still going on, you should probably have an assistance.If you utilize a diffuser of any kind, such as garryfong, there is one significant drawback. The rubber holder they provide is fairly substantial. With this rubber holder, using diffusers or garryfong is all but impossible.But find your ways: I use double-sided tape, rubber bands, and thin hair bands.Creative thinking is limitless.Thanks

Since I have never purchased gels before, I am unsure of how to evaluate them in comparison to other vendors, but based only on my experience with them, I believed they were of decent quality for the price I paid ($13.89). I got two sheets, each with seven colors. It was thick enough. The fact that they were covered in protective plastic on both sides allowed me to sketch over them with a Sharpie, cut out the form I needed for my lamps, and then take the plastic off (and stray sharpie marks). The yellow and green appeared a touch grayish and greenish, but when I doubled them, they appeared richer. Without the need for additional color, the red and blue appear fantastic. Since I can use two filters to create a broader template of colors, I would say that it is excellent that the filtering isn't too strong.

Simply for the yellow, orange, and red filters, I purchased these. I used an exacto knife to trim them to fit my Kindle Paperwhite's screen because at night the PaperWhite turns into a Paper-GREEN! (I don't know who stole my paper cutter...) When I'm winding down at night in bed, I read on my Kindle, but it emits this strong greenish-blush light that, according to research, is the worst for interfering with circadian rhythms and sleep parameters like when to fall asleep and the restorative quality of sleep. Now that I've moved as far away from green-blue as I can in the visible light spectrum, my Kindle is 100% totally viewable at night without any distortion or blurring. It also has a RED light. I'm now cutting an orange or yellow filter to fit, adding velcro strips to the borders, and putting that on my laptop screen at night so I can still work without sacrificing my sleep. The one thing you should be aware of is that these do seem to scratch easily, so keep that in mind. On the plus side, these were really affordable at the time of my purchase, so worst case scenario if you scratch one up it's an easy replacement. I used to read on my Kindle while wearing the UVEX industrial orange glasses at night, which also work quite well, but I prefer to do so while lying on my side, where the glasses bite into my face and make reading less enjoyable. The UVEX is still a great tool that I use for different applications.

I was awake due to my alarm clock's dazzling white-blue glare. I thought I would try to put some red film on my alarm clock to help out as I remembered that red flashlights preserved night vision from when I worked in an astronomy lab. This product is fantastic; I bought it. To prevent any light from leaking out the sides, I cut it to fit the size of my clock's face and then fastened it on with electrical tape. Although it took three layers to get it dark enough for me to sleep comfortably, I can still see my clock when I wake up. The digits now shine a deep red, just like on a typical clock. To read novels on my iPad in the dark without harming my eyes, I'm considering using another sheet as a night overlay.

I just needed red, like another user. (Actually, I ordered a single sheet of red at first, but the shipping was delayed, so I decided to go with these instead, even though I now also have a bunch more colors that I don't need.)(Having said that, the yellow and orange ones work well for blocking out blue light before going to bed by placing them over your laptop or monitor. a great deal more comfy than amber spectacles.)I wanted to modify the temperature display on the new air conditioner we bought from its blinding white color to red. I had to build numerous layers in order to achieve the desired red color. I had initially taped the edges of two pieces when stacking them. I then changed my mind and wanted something darker, so I took the pieces out and ripped the tape off so I could add two additional levels to the stack. A tiny coating of film came off with the Scotch tape when I took it off. Then, additional film started to come off the other side as I turned the piece over and taped one corner.This is not a concern to me. I'm not sure if this movie needs to be taken off or not. The filter "comes with protective coatings, protect the filter from being scratched," as stated in the description. However, it is unclear if these protective coatings are intended to remain in place after using the filters.I ultimately decided to take this film off of each of the four pieces in my final stack (easy to do: apply a small piece of scotch tape to a corner and pull back).Other, comparable products are offered for sale on Amazon. Because they were used near lights and the top layer "melted," some of these received one-star evaluations. If these reviewers had first removed the exterior film, do you think everything would have been alright?This DOES NOT mean that you should disregard the warning that says, "Please do not leave the product too close to the light that is on, or it will be melted."

I actually bought this item to make stained glass windows look like they were in my room. The early sun was harsh, but I didn't want to totally cover the window. For what I used them for, they performed ok. However, the lighter colors in the pack, like as green, orange, and pink, are mostly translucent and don't produce a lot of color. For those who are using this information for its intended purpose, I'm sure it will be helpful. All I could think of was to use two gels in order to increase saturation. Oh, EVERY GELL IS WRAPPED IN PROTECTIVE FILM INDIVIDUALLY. Finding a corner to peel from is time-consuming and difficult to remove.

I purchased these to cover some obscenely bright white lights on my microwave over the range. used a green and yellow colour combination to soften the harshness of the light.There were two of each gel colour, and since they were well-built and could withstand the heat from the range, I'm confident they would work well with flash bulbs or anything drawing less than 60 or perhaps 100 watts.

I bought this red gel filter to protect the light in my car's hatch and two utility lights. This is due to the fact that I frequently organise and take part in star parties, a public astronomy event, for my institution. In general, red light reduces light trespass and maintains dark adaptation. This was necessary because the hatch light switch's positioning and design prevent me from turning it off when the hatch is open.

Filtering visible light is usually done with a piece of glass or plastic that has been treated with a substance that absorbs some of the light that passes through it. The amount of light that is absorbed depends on the type of filter and the thickness of the material.
Assuming you would like a detailed answer: One way to turn a white light into a warm light is by using a filter. By adding a filter to a white light, it will change the color of the light, making it appear warmer. The color of the filter will determine how warm the light will appear. For example, a red filter will make the light appear warmer than a blue filter.
Yes, it is safe to cover LED lights. The LED light emitting diode is a solid state device that is not fragile like a glass bulb. Therefore, there is no risk of the LED breaking and causing injury.
It is safe to put cellophane over lights as long as the cellophane is not in contact with the light bulb. If the cellophane is in contact with the light bulb, it could cause the bulb to overheat and possibly break.
Light filters are devices that are placed in front of a light source to alter the color or intensity of the light.
