SleekLighting LED-Fireworks ST19 -Blue Color

The bulb is beautiful when lit. It does not give off a lot of light; it is more for a beautiful effect. It is worth noting that the box says “Do not use in totally enclosed luminaries”. I believe the reason for that may be that it needs to have ventilation to keep it’s internal circuit from overheating-perhaps the supplier can better explain why it cannot be totally enclosed. So if you plan to use it in a totally enclosed fixture, this probably is not the right bulb. Other reviewers spoke to the effect of the bulb so I won’t repeat that except to say that it is a cool 3D space like appearance.

its advertised as a light bulb that somewhat projects a starry looking pattern on your walls and celling. its not the case. the bulb itself has a nice pattern on it, but thats it. it just puts off a blue glow. pretty bulb but thats it

This bulb is five stars or one-star depending on your use. The one-star reviews are true, it puts out almost zero illumination. I'm using it as an accent lamp in an unusual base on a table and the bulb is what makes it a conversation piece. Definitely worth the five stars. When the bulb is off in daylight it is highly reflective metallic silver. When it is on it is deep blue with lighter blue stars and blue dots. If you have seen an infinity mirror this bulb produces the same effect. The stars have actual depth and are not just light shining through a cutout. When used for an accent lamp it is a great addition to my living room. Yes, that's a 35mm film camera converted into a lamp.

You're not going to use this to light up a room but it is excellent for an accent light or even a night light. It is perfect for a space themed room (I used it for my homemade rocketship lamp).

They are about as bright as a night light, but Wow! Beautiful and alluring, these bulbs are a pleasure to have in my home.
