For forty years, I worked for a chemical company that made the base products necessary to product LED (light emitting diode) light bulbs. So, if you would like to hear a dissertation about trimethyl gallium and trimethyl indium substrates and their pyrophoric and water-reactive properties, well, you’ll have to come back another time. What we will talk about here is a series of LED bulbs, all of the G9 type, that are currently sold through Amazon.com.

Buyer’s guide
This feature of our review is designed to give you additional insight into some of the key terms, definitions, specifications, and features that come into play in selecting the optimal G9 LED bulb for your specific application. In addition to the information here, we also encourage you to check out the manufacturer’s web site and other relevant web sources.
Color
The Kelvin Color Temperature scale measures the color of the light spectrum emitted by these bulbs. You will see the color specifications for many of these bulbs noted in our comparison table in Section 2 of this review. The complete table is as below:
Lumens
Rather than bore you with a scientific definition that, frankly, makes my head hurt, in simple terms, lumens = brightness. The higher the number of lumens, the brighter the light provided by the bulb. You can find excellent information inking lumens, wattage, and color to light bulbs at the site below. Lumens per bulb are also listed in the comparison table.
Conclusion
LED chips are used in a large variety of consumer applications, including cell phones, computer screens, televisions, etc. It is their use in lighting; however, that gives new freedom and advantages to consumers. As this technology has emerged and developed, LED bulbs are not priced competitively with other types of light bulbs. When their reduced energy requirements, and corresponding costs, are factored in, they not only save the consumer money but increased sustainability and our “green” presence. Now add in the extended life of these bulbs, with some lasting as long as 30000 hours, and you can see why LED bulbs have begun to take over the lighting marketplace.
We hope this review has been helpful to you in providing you with information to make the step-change to LED bulbs. With all their advantages, they are truly lighting the path to improved environmental sustainability.
Is it safe to use g9 led bulbs while illuminating a bathroom wall?
You can use g9 leds in your bathroom just like any other lamp. However, it is advised to check the bathroom electrical zoning regulations that relate to the precise lamp position.
I’ve got a set of 25W halogen fixtures. So, my question is – can I put a 5-watt LED in those fixtures? And while we’re at it, I want to replace my G9 Xenon with a JandCase from your list. Can that be done?
Yes, in contrast to a popular myth, LED lights can (and should) be used with halogen fixtures. And to answer your question, a 25W fixture will go perfectly with a 5W LED. Since its max wattage is five times higher, the LED will stay pretty cool for long hours. The biggest issue in this case may be compatibility. So, before buying a set of LEDs, check their length and make sure it matches the fixtures.
Next, the JandCase G9 Led Bulb is one of the best options on the consumer market, and it can, indeed, be a replacement for the G9 Xenon.
