Coralife 05473 Straight Pin Compact Fluorescent Lamp, 36-Watt, 10K

Installs easily, fits my 29g Biocube perfectly. I've used other brands, but these provide nice light and the price was right. No defects.

I had been looking all over the place for these bulbs. I have a custom type tank that uses these bulbs. Apparently they also fit the BioCube. None of the Petsmarts or Petcos or even Walmarts near me carry these. They have them on their websites, but Amazon was the cheapest. Definitely works as expected and is super bright. My fish are happy now that they have light again!

It's the proper replacement bulb for 29 gallon biocubes so it's a perfect fit. The price is a little high but it's difficult to find in pet shops so well worth the purchase here.

Product came in as ordered and in a timely manner. very happy with product. Was worried that it would get broken since this is my first time ordering online for a bulb. Came in unbroken and is working great. Thanks

Second time I've gotten a defective 10,000 K lamp from amazon. And second time I am going through the return process. Last year when the lamps were needing replacement, in my Biocube 29g, I ordered the normal 36 watt 10000K and 36 watt actinic lamps. The 10000 k lamp I received for some reason had the same hue as the actinic lamp and was still labeled 10000k on the lamp! (which had to of been a manufacture defect)I returned the lamp.

This year I decided to try again because the pricing is reasonably better than the local stores $5 to even $10 cheaper than in my area. The 10,000k lamp I received this time around was defective and did not light up, only flickered about once or twice before giving out. I am now waiting for a replacement, surely if something is wrong with this one I will buy my aquarium products elsewhere from now on.

Also note the actinic lamp I received this year was in excellent condition but was also from an out side vender on amazon.
