Buying on AliExpress for the first time?

This process is done through the AliExpress mobile app, where most people shop. Two things matter: don’t use Buy now and enter the coupon only in the order summary in the Promo code field. After you click Pay now, you can’t add it anymore.

1. Copy the code and click GET THE DISCOUNTIn our article, copy the coupon and click the button GET THE DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart, not Buy nowOn the product card, scroll down and click Add to cart. Don’t use the Buy now button—this skips the cart, so later you won’t have a place to enter the coupon. Before that, make sure the variant is correct: color, version, and whether it ships from an EU warehouse.
3. Continue to Checkout via the cartA pop-up will appear: Added to cart!—tap Check it out. If it disappeared, open the cart using the icon in the bottom-right corner. In the cart, check the product and quantity, then tap the red Checkout button. Only the items marked with the red circle are included.
4. Fill in your address and card, then look for Promo codeIn the order summary, first enter the delivery address and payment card at the top. Below that, there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check your savings and payIn the section Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount again in the order summary. After you click Pay now, you can’t add a coupon anymore. If Apply shows an error, the code has either expired, doesn’t apply to your item, or your order doesn’t meet the minimum amount.

Store Coupon also belongs in the same field. — a coupon from the seller itself, which isn’t always available and changes day to day. It can’t be combined with an AliExpress coupon, so try both and go with the one that gives you more. Coins are added automatically.

16 million colors and finely adjustable color temperature

The main advantage of this bulb is that you can change not only the light intensity, but also its color shade. Warm white for relaxing evenings, cool white for focused work, or colorful ambient lighting—everything is easy to set up via the Yeelight or Mi Home mobile app.

The bulb supports 16 million colors and a color temperature range of 2700 to 6500 K. There’s also convenient dimming that you can control manually, by voice, or through automation in the apps.

Compatible with the biggest systems and easy pairing

A big advantage is support for Apple HomeKit, Amazon Alexa, and Google Assistant. So if you use any of these platforms, you can add the Yeelight W4 bulb to your ecosystem without any problem. Voice control works perfectly, and you can also set up automations like turning the light on when you come home.

Another advantage is that the bulb doesn’t require any central hub. Just use your WiFi network and the app. The connection is handled by the WiFi + Bluetooth Low Energy combo, which makes the pairing process very fast.

Modern design and standard E27 mounting

The bulb has an elegant matte finish and a classic shape that fits any lamp or light fixture. It uses the standard E27 socket, meaning you can install it practically anywhere without needing an adapter.

The bulb dimensions are 60 x 60 x 110 mm and it weighs very little, so it won’t strain the lampshade or other parts of the fixture. Thanks to low power consumption of 9 W and a luminous flux of 806 lumens, it’s ideal as main or additional lighting in any room.

Sync with music and games

Yeelight W4 Lite also offers a fun music or game synchronization feature. This function works with the Razer Chroma™ RGB platform—perfect if you’re a gamer or you already have an RGB ecosystem.

Plus, you can set timers, groups of multiple bulbs, scene modes, or schedule automatic dimming and turning lights on/off. Everything works through a well-designed app available for Android and iOS.
