Industry Tips--How to choose suitable Ceiling Light
While Ceiling Lights may appear simple,choosing the wrong one can be a real headache.Insufficient light intensity ,glaring flickering,or yellowing after just two months of use can severely impact the aesthetics and comfort of your home.How can you choose the right ceiling light from such wide variety of options?Winway will assist you understand the following key details to help you make an informed choice and ensure satisfactory results.
1. Suitable Size
When choosing the ceiling light,size is crucial.The size of light should be appropriately chosen based on the installation space;Neither too large nor too small is suitable.Different sizes are recommended for bedrooms and living room to ensure optimal light coverage.If the size too large ,it may take up too much space in the living room,severely obscuring the overall design and highlighting the lack of the height in the bedroom.On the other hand,if the size too small,corners will be dimly lit.To ensure the right size,you can follow the following method to choose:For bedroom lights,the diameter can be calculated as “( length+width)/12”(in CM);For Living Room Lights,the diameter can be estimated as“(length+width)/10”.If you are not sure about the specific size ,you can refer to the figure below:

2. Ensure true color reproduction
When purchasing Ceiling Lights,many people focus solely on the design,brand and price,but overlook a crucial factor:the color rendering index(CRI).This is crucial because the higher the CRI more accurately reproduces the original color of an object,minimizing color shift,improving visual comfort,reducing visual fatigue and protecting eyesight.Therefore choose a CRI of 80% or higher.Avoid lights with CRI of 80% or lower,as these will result in poor color reproduction,distorted and dimmed colors.Long term exposure to such lights can easily lead to visual fatigue and even impair color discrimination.Therefore CRI is crucial when selecting the light,especially for those with children or elderly care in the home.The CRI of Ceiling Lights provided by Winway is maintained at above 80% ,ensuring high-quality color reproduction,better protecting eyesight and giving you a better lighting experience.

3. Pay attention to flicker
Except for CRI,this is one lighting indicator which often overlooked because it’s generally difficult to detect with the naked eye.
The Ceiling light without visible flicker provides stable light,reduces visual fatigue and protect eyesight,it will suitable for Children’s rooms.Adopt simple and available test generally:Using your phone’s camera to record a video directly at a lit Ceiling light,if without black streaks flicker,there’s no flicker.Ceiling light with flicker exhibit noticeable light fluctuations which can easily cause visual fatigue and impaired vision,will damage eye health use in a long-term.

4. The light not too clod,the wattage not be too low
Light has color.Generally speaking,whether in the office or at home,we use main three lighting color:Cold white light,Warm light and Neutral light.All these called color temperatures.Higher color temperatures(above 5000K) create cooler,whiter and brighter light;Lower color temperatures(below 3000K) create warmer,yellower and more inviting light.Normally speak warm and cozy spaces create a sense of comfort so that warm light with the color temperature of 3000K to 3500K is preferred for Home Lighting.However some people dislike the particularly yellowish light so can opt for 4000K warm white light,which closer to daylight and create a more soothing effect;
Kitchen and bathrooms are special spaces in the home,ideally suited to 5000K white light;
Cool white light above 5000K tends to have a bluish cast and not recommended for use in home,except in certain commercial spaces.
Friendly Reminder:The color temperature of lights in the home can be mixed and matched.For example,ceiling lights and downlights in the corridor can use 4000K warm white or 3500K warm light for large-scale lighting.Small ares such as table lamp and linear lights on cabinets can use 3000-3500K warm light for atmosphere lighting.This combination of lighting will make the home feel more cozy.

Beside light color,brightness is major factor in choosing a lamp,and this is where the wattage of the lamp comes into play.The higher the wattage,the brighter the light.If don’t know how to choose,can refer to the picture as follow↓

5. Appearance Design
As the primary lighting source in your home,ceiling light provide both illumination and decorative functions,so choosing a style that matches the overall decor is crucial,When choosing different styles of lights,consider the overall decor of your space and make the appropriation choice.The lights should illuminate the space while also adding the beautiful,comfortable and layered feel.

6. Material
There are many materials for ceiling light on the market,each of them has certain advantages and disadvantages.You can choose the appropriate one according to the actual use environment and lighting requirements:
| Name | Advantages | Disadvantages |
| PMM (Acrylic) | --Excellent light transmittance:High visible light transmittance and soft,without glare,low yellowing; --Balanced mechanical properties:High hardness,easy surface polishing,impact resistance and shatter resistance; --Flexible processing:the variety of molding processes are available.Facilitating the creation of complex shapes; --Environmentally friendly:No harmful substances are released at room temperature. | --Poor heat resistance:The heat deformation temperature only 70-90°C and it easily softens and deforms at high temperature; --Poor scratch resistance:Surface hardness is lower than glass.It is easily scratched by daily; --Higher cost:The price is higher than general plastics such as PVC,PP. |
| PVC | --Extremely low cost:Highly cost-effective,suitable for large scale mass production; --Strong chemical resistance:Resistance to corrosion by conventional chemical; --Excellent processability:Can be produced in both soft or hard forms through injection molding,extrusion and calendering; --Best flame retardancy:Contains chlorine,achieving V0 flame retardancy without need for additional flame retardants,ensuring safety. | --Weak weather resistance:Long term exposure to sunlight can cause aging,brittleness and fading; --Susceptible to cracking at low temperatures:Soft PVC become hardens at low temperatures,while hard PVC impact resistance decreases significantly at low temperatures.Making it unsuitable for outdoor use in cold environments. |
