Breaking News - Full Range of Class A Filament Bulbs Are Available In Sunplan
2023-02-23In September 2021, the new ERP of EU was officially implemented. Its core index is the improvement of light efficiency standard. Since the introduction of the new standard, only Philips and OASRAM have launched Class A products because of the high cost and technical threshold. Class A requires 210lm/w.
At the beginning of 2022, Sunplan's project on high light efficiency filament lamp was approved. After half a year of development, the product design was mainly completed. In October 2022, based on the light attenuation of 1000h ignition point, the lifetime is inferred to be 30000h.
In February 2023, after the adjustment of the design and parameters, with the performance improvement, lifetime is improved to 50000h. Thus, the energy efficiency class A products were officially launched. According to the schedule, SUNPLAN launched a full series of Class A products including C35, G45, A60. This is really a great milestone since the establishment of the company.

Sunplan Launched Portable Low-voltage Table Lamp Products
2023-02-23In the past years, Sunplan mainly focused on producing light bulb. The rich customization only can be reflected through the installation of the bulb to the 230V lamp holder. But with the introduction of portable low-voltage table lamp in December 2022, it was changed. The message such as blessing and mood is integrated into the bulb, and combined with custom ceramic lamp base, more products portfolio derive.
The integration of glass and ceramic is closer to nature, more friendly to the environment. The overall texture and grade has been improved. It not only can be illumined on the desktop, but also portable to use at outdoor. The innovation belongs to the cross-border lighting. What’s more, it is also a perfect gift, you can express your love by the lamp.
The first generation adopt ceramic base and is powered by dry battery. The second generation will be upgraded to a metal base and powered by lithium battery. After the upgrade, the bulb and base will also be detachable.The base can be matched with more bulbs (notes: only low-voltage bulbs produced by our company can be used). According to different moods, you can change the bulb with corresponding message. It is really amazing, the lamp bring us so wonderful experience.

How to Choose LED Filament Bulbs ?
2022-05-20Today the LED filament bulbs are so popular and widely used that so many customers want to have them at their own house or stores. It’s not difficult for them to buy them at a local store or online stores like Amazon or even Aliexpress from China. Maybe you are the lucky guy to receive the reliable ones. But with these questions in heart, it will help you understand how to choose led filament bulbs ?• Is the circuit layout chaotic or reasonable and well aligned ?What is the substract material ?LED Filament bulbs are known as using COG technology (Chip on Glass), but actually glass is not the only substract material that being used. There are mainly four materials, glass, sapphire, ceramic and metal. Glass has the highest light transmittance but bad thermal conduction and not electric conductive. Metal doesn’t transmit light and is very easy to burn out due to bad compact with the led chips and phosphor. Ceramic doesn’t tranmit as much light as sapphire and glass, and Sapphire, which has been used on Iphone cameras, are the best material yet most expensive materilas for the led filament bulbs. In Sunplan Lighting, we have two ranges, one is using sapphire material, the other is ceramic equipped with more powerful led chips to insure the light reliability and lifespan.What driver do you use ?People used to ask weather it’s IC or RC drivers. But actually there are even several solutions for RC driver which closely effect the driver reliability. So you may simply ask the suppliers to show you the photos of the drivers and check below:• Does the driver have heat dissipation glue ? (depends on the bulb power)• Does the driver have lighting surge protention circuit ?• What is the brands of Electrolytic Capacitor being used ?What is the gas filled in the glass bulbs ? And how much ?Almost all factories are using He and H2 while Sunplan Lighting has got Patent here in application of the Penning Effect. Which brings rapid convection of the gas for faster heat conduction, also help detect gas leakage during the gas-filling process. Inappropriate gas proportion filled will reduce the bulbs reliability and speed up the lumen lose and lifespan.There are still many questions you could ask, like which led chips and how many pieces are used ? What’s the brand of the silicon glue being used over the led chips ? What’s the gold wire for the led filaments ? I am pretty sure most of the suppliers cant give you a decent answer. However all of those are greatly effec the whole performance and reliability of the products. And we are proud to see that our bulbs have an excellent performance during the ErP 6000hrs light test. 98.42% lumen maintenance after 6000hrs. The ITS testing lab where our bulbs are being tested, told us you should declare your products to have a lifetime of at least 30,000hrs, not 25,000hrs as you declare.If you dont know how to choose led filament bulbs, you could simply write us info@sunplanlight.com for a quote. Although we mainly work with major importers and distributors, we also work with many lighting designers and interior decor companies. With our strong R&D and production ability, we could also provide bespoke items to meet your request. Sunplan Lighting, will never let you down !
