This product works exactly as advertised. I have used them for two 8 bulb fixtures and plan to use them again. The screw down tab is exactly what I needed. I would recommend to a friend.

Used these LH0023 (T503) lampholders from Semperlite to repair my Coralife T5 H.O. Lunar aquarium fixture - saved big $$$ not having to buy a new fixture or buy the pre-wired replacement ""End Caps"". Repair was easy, and the lampholders fit perfectly, exactly like the originals.

exactly what I looked for

I could not find this light socket (made in China) from other vendors. The descriptions and dimensions are very clear that I was ordering the correct item. The shipping cost to Hawaii included USPS making it very cost effective. The delivery time was very fast.
