Marine Color9w Lamp Bulb, Spare Bulb for Sunsun Hw-303b 304b 404b Jup-01 Filter Cf400, Cf500, G23 2 Pin,

Hard to beat the price and it fits my sun sun 340 perfect

I installed this in my canister and the light is on and my water is clear. Just avoid touching it with your hands. Either use a paper towel or gloves when handling. The oil/dirt from your hands overheats the glass when it’s on. It shortens the life

Works as described, has lasted more than 6 months with continuous use

Instalada en un tanque de arrecife, funciona muy bien para control de algas en la columna de agua.

Perfect replacement bulb! Same as the Sun-Sun brand and great quality as well!!! These types of bulbs doesn’t matter the brand aren’t supposed to be turned off an on very often because it shortens the life of them. But this bulb was amazing quality compared to Sun-Sun brand or others like it. My tank is healthy! There’s also three other expensive fish in that tank that were hiding. I’ve got over a $1k in an rare type of tiger datnoid, also a rare fire eel, and a white diamond panda angel fish in there. That is also a 75 gallon tank. Which I’m getting ready to split them up and move the Tiger Datnoid, fire eel, and Clown loaches. To there own 125 gallon tank. I already have just been running the tank with a few neons in it to make sure the water is stable. So that way I know it’ll be ready for a high bio load. But I have 3 of the Same big Sun-Sun’s with this same sterilization light system built in on them as well. They do take a bigger build since they are a bit bigger filters. But if i ever need replacements. I know to come back here and buy them from this company!!!! Only thing I would suggest is that they package the product a little better especially since how hard shippers are on small products like this!

Exact fit for SunSun HW 303B. Everything works as intended! Keep in mind that this bulb is not intended for long hours/days of use, as it will burn the media trays. I know, I've had to buy new trays because of this. Nice, fast delivery and very well packaged! Highly recommend.

Good

Received them a day early but one was broken. The other has been working perfectly
