TZHILAN Blue G4 LED Light Bulb 12V AC/DC 2W 48×3014 SMD 20W Halogen Bulb Equivalent, Capsule Spotlight Lamps for Landscape Decorative Lights Holiday Celebration Pack of 4

Great

These were the perfect substitute for the existing pin halogen style bulbs in the bunk area of my boat ... In my case, I had a chrome ring / glass lens to cover them, and the fixture has a recession built-in ... This allowed the LED to seat ... Otherwise they would NOT have, because of the increase in O.D. ... That used 3 bulbs -- the 4th, I put in the courtesy light on the radar arch ... It's now been over a year and all 4 still work properly

I replaced two white LEDs with this red one inside the cabin of my sailboat. The crew is not waked up now when the anyone has to move around downstairs.

Product not as labeled!! Ordered on pack of Blue and one pack of Green. They packages were labeled as such, but all bulbs in the Blue package are green. So now I have 8 green lightbulbs instead of 4 of each. Other than that, they work as expected.

The media could not be loaded.  Beautiful evenly dispersed blue. Every LED worked perfectly in my G4 bi-pin retaining wall lights. Would definitely buy again. I only have about 200 hours on them, so I can’t vouch for longevity. I put them in for Christmas this year to carry the theme around to the right side of the house and they were just beautiful, same blue as my icicles.

Not as bright as I expected.

Arrived as promised. Very easy to install. Good color and brightness. After being lit a few minutes they will get very hot so be careful.

It should be noted that the unit is not made of plastic or glass but encased in silicone. I'm using this bulb to retrofit a boat cabin light and so far I I'm pleased.
