Clearline Concepts Class 3A Laser Yo-Yo (glow)
Exhibit #2813
ShapeStandard (-)
PackagingBubble Carded
OwnerRick Brough

The first–and only–model of yo-yo ever sold retail that housed an actual class 3A laser. To add to the spectacular red laser beam emitted from one halve (the other halve contained a single, internal red LED), the entire yo-yo also glowed in the dark.

The yo-yo itself has a DANGER sticker affixed to the one side of the halve that contains the laser. The sticker outlines the following laser specs:
Max Output: <5mW
Wavelength: 650nm +-10
Class IIIA Laser Product

All "laser-like" yo-yos that have ever been sold in the past were nothing more than harmless LED lights that simulated a laser beam. (See the Gaelex Toys "Supreme 2000" yo-yo exhibit for one such example.) The yo-yo model in this exhibit, however, was the exception. In August 1999, when the laser in this yo-yo was manufactured, it apparently met the laser standards defined by the US Food and Drug Administration for toys. Today, it is highly unlikely that would be the case for this yo-yo. Class IIIA lasers are frequently used as pointers for astronomical purposes because of their power and strong beam. However, unlike most class I and class II lasers, 3A lasers (also known as 3R) can cause serious retinal injury if the beam is focused on the eye for more than one quarter of a second.

Both the laser beam and LED in this yo-yo activated or "turned on" only when it was rotating at a certain velocity on the end of the string. Note that the back of the packaging contains numerous warnings. When yo-yo rotation slowed, the beam and LED instantly turned off. Other than high speed rotation, there was no other external method on the yo-yo to engage the laser beam or LED.

The yo-yo was made in Taiwan but it is unclear for whom. The name "Clearline Concepts" appears on the front and back of the packaging. They were located at 85 Fulton Street, Boonton, New Jersey in 1999. However, on the bottom of the packaging the copyright is 1999 and credited to Team Products International Inc. 85 Fulton Street, Boonton, New Jersey. An Internet search revealed that Team Products International never resided at 85 Fulton Street. Team Products was a supplier of consumer electronic products to stores such as Wal-Mart and Target. It's possible that Clearline Concepts contracted with Team Products International to supply the lasers for the yo-yo.

The yo-yo came pre-installed with four LR44 batteries (2 for the laser in one halve; 2 for the LED in the other halve). The yo-yo in this exhibit has small hairline cracks near the outer edges at the 8 o'clock and 2 o'clock positions (hence the Condition 9 rating). The yo-yo used a variable starburst response molded into the plastic. It also used a metal roller bearing axle, similar to the plastic roller bearings used in Yomega yo-yos.

A very hard-to-find yo-yo nowadays and one of the more interesting–albeit dangerous–exhibits in this museum.

Original retail price: $17 US.
