G9 LED bulds compared,
Verified Purchase(What is this?)
This review is from: G9 SMD LED Light Bulb 2.5Watt 250 Lumens Warmwhite Energy saving LED Technology replacement for 40w G9 halogen G9 with Aluminum body
I purchased 3 different G9 LEDs to compare side by side and see which best fit my lights. All made by Long life Lamp Company and sold by Strictly Lamps, one was a 1.9W capsule, one was a similar 2.5W capsule (these both have silver bases and visible yellow LEDs) the third was a 2.5W ceramic which has the white base and domed bulb. All in warm white 3000k.
All were very impressive and brighter than the standard 25W which looked a dull yellow when compared side by side. The 1.9W has all the LEDs facing forward so acts a little more like a spot light than a regular bulb but good amount of light still comes out sides. The 2.5W with silver base is longer and has additional LEDS around the circumference so it puts out a more radial light. The 2.5W ceramic puts out good radial light from the domed bulb.
If size was no issue I would probably go for the 2.5W with silver base. However at 24mm diameter it was just too big for my glass tubes on ceiling light (but fit into larger tubes on floor standing light). Both the 23mm diameter 1.9W and 18mm diameter 2.5W fit into my ceiling light. I prefer the radial light from the 2.5W than the more forward directed light from the 1.9W.
So if it will fit then this 2.5W is great, if you need a smaller diameter try the 18mm 2.5W which although different visually still works very well.
