2 Pack 6 Watt Replacement Bulbs F6T5/BL Fluorescent Tube G5 Base 9 inch Full Length Replacement for DT2000XL and DT2000XLP and DT3012

Bulbs worked as they should, to replace the old ones in our lantern. Much brighter than original too, color is a cool blue. The length was good for the lantern, glad to still have an option to replace the bulbs rather than buying new a better use of resources, both money saving and avoiding trash. We hope that the quality is as good as the original and the bulbs last.

Great device and helpful for the price

I love the replacement bulbs to have them on hand so when they go out that I have them to get replaced, put on top of that if you buy the bulbs, you save a lot of money where you don’t have to buy the whole thing

I read the reviews but bought these anyway. I figured I'd give it a try. The first bulb almost lasted a whole month. I just noticed yesterday that the bulb was burned out. I put in bulb #2 today. I like the look of the bulb. It works well when it's working. It does attract bugs. Will I buy another one? No. Either I'll try to find a more reliable bulb or just buy a whole new bug zapper. Advice? Avoid these bulbs. UPDATE. The second bulb lasted 5 whole weeks! 6/10/21 to 7/18/21. If Amazon wants to send me some replacement bulbs, I can use them. Just don't expect them to last long. In the meantime, I'm going to weigh my options. I need a functioning bug zapper.

***I wrote the original review below two days ago. Within hours, I got an email from the seller asking if I would like a replacement or a full refund. Mind you, I ordered these back in March, four months ago. I replied, sure, send me a replacement. They arrived on my doorstep this morning. Even though I stand by my original review, I'm adding one star because they did actually do the job. They attracted and then the zapper killed lots of bugs. I'm adding another star because they stepped up when they didn't really have to and was not at all expected that they would. And one more star for the apparent seriousness they took the situation and the speed with which they took action.*** I waited to review these bulbs to give an accurate impression. The first thing I noticed is that these bulbs are fatter and longer than the one they were replacing. Bulb manufacturers worldwide agreed to a standard sizing and numbering protocol decades ago. So an F6T5 bulb should be the same size as any other F6T5 bulb. Unless they were made as knockoffs in a country that does not really abide by international standards. I wonder what the standard is for the longevity of an F6T5? The first one lasted all of one month. The second one lasted one month. At least they're consistent. You can make an incandescent bulb that doesn't last very long by using cheaper material for the filament. How do you make a fluorescent bulb cheaper? It's a glass tube filled with gas. Anyway, these bulbs are inexpensive so I would recommend getting the subscription to have them coming at regular intervals every two months or so for the 2 pack. That last bit was me being sarcastic in case the seller reads this and is thinking, "What a great idea!"

Fit good

I’ve ordered these previously with no issues and they work great. However, the last 2 times I’ve ordered them, they did not work when I got them! 😡 You could hear stuff rattling inside. They are not packed very well, so I’m guessing they are thrown all around during delivery. I have ANOTHER set coming tomorrow, so I really hope those work!! They are great, but please package them better!!

Good and bad
