E10 Mini Bulb Holders, Package of 10, Miniature Lamp Holders for Simple Circuits, Physics

These were purchased to fit E10  Eiko 245 2.46V .5A G3-1/2 Miniature Screw Base Halogen Bulbs , which they do. One of the bulbs was too large for the bulb holder, but the rest were compatible, so I am chalking it up to a defective bulb, not a defective bulb holder.They are on the cheap side, but they are a simple construction, easy to understand and handle, and take up very little space for storage when your project is done. Electrical wires can easily be attached via a loop or alligator clips. Went perfectly with our child's science experiment.

I like this product a lot. I really needed a product with a closed insert for the bulb to screw in. I ordered a bunch for my classroom that had a U shaped bulb insert and they bent easily and were disappointing. This product is much more reliable.

Ordered because parts were missing on the kit boxes ordered prior. Works as described.

Worked well for our science project.

Worked well...you do have to adjust the base for the bulb to light. Perfect for school science fair, etc.

GREAT lamp holders for science projects.

Exactly as advertised and worked for our circuit building.

I ordered these for my classroom. Some of the holders broke when the students tried to put in their bulbs.
