Simpliest consturction causes this LED light very durable. "Rainbow" led with built-in IC, current limiting resistor, slide switch and batteries. All in pretty hard inner case and soft outer case (like enlarged ping-pong ball)
The solder is weakest place in circuit. If ball case is curved, you can't fix it perfectly. Boxes always come crumpled, it causes non-marketable and non-gift view. For such simple construction price may be lower.
I thought contains an independent IC-card that I could use in my own projects. But there just "built-in IC LED" thich i can not modificate (change brightness, or shift color channels, or separate emitters). I can use this "LED snowball" only as is.
in spite of all pros and cons it's very fun and multi-use thing. Mood light, emergency light,juggling ball, baby toy, (if wrap it in transparent balloon) fishing light or glowing float, etc.
