Differences Between ST19 and ST64
To begin with, it should be noted that these are almost technically identical types of bulbs, but they still have some differences. The biggest difference is in their size and design. The characteristics that I will mention below in the text depend greatly from manufacturer to manufacturer and do not take them for granted. Use this text more as an advisor and to better understand what you should pay attention to when choosing bulbs.

Wattage and Brightness
The wattage and brightness of a bulb are important factors to consider when choosing the right one for your space. The ST19 bulb typically ranges from 40-60 watts and produces around 400-600 lumens, while the ST64 bulb ranges from 40-100 watts and produces around 400-900 lumens. This means that the ST64 bulb is generally brighter than the ST19 bulb and can be used in larger spaces or areas that require more light.
Design and Aesthetics
One of the main reasons people choose ST19 and ST64 bulbs is for their vintage-inspired design. The ST19 bulb has a slightly elongated shape and is often used in pendant lights, chandeliers, and other decorative fixtures. The ST64 bulb has a more rounded shape and is often used in wall sconces, table lamps, and other fixtures where the bulb is visible.
Color Temperature
The color temperature of a bulb refers to the warmth or coolness of the light it emits. The ST19 bulb typically has a warm, yellowish hue with a color temperature of around 2700K, while the ST64 bulb can range from a warm yellowish hue to a cooler, bluish-white hue with a color temperature of around 2200K to 2700K. This means that the ST64 bulb can be used in a wider range of spaces and can provide a cooler, more modern look if desired.
Price
Price is always an important consideration when choosing light bulbs. In general, the ST19 bulb is slightly less expensive than the ST64 bulb, but prices can vary depending on the brand and where you purchase them.
Conclusion
Both the ST19 and ST64 bulbs offer unique vintage-inspired designs and warm, yellowish light. The main differences between the two are their size, brightness, color temperature, and design. If you’re looking for a bulb for a decorative fixture like a pendant light or chandelier, the ST19 bulb may be a better choice due to its elongated shape. If you need a brighter bulb for larger spaces or areas that require more light, the ST64 bulb may be a better option. Consider the color temperature and your desired aesthetic when making your decision.
