As another reviewer states, 500 watt bulbs burn out very quickly with light use. I'm very careful to keep clean when installing. What gives?!

I've had very good luck with mine, and no issues. Be sure to use dielectric grease on the connections before installing the bulb. Its possible a lack of grease along with thr high wattage could be heating up the connection and shortening the bulb life. Use a plain paper towel when handling the bulb. Oil in even the cleanest skin can shorten bulb life.

You should not use more than a 60watt bulb. I had bulbs last3 to5 years.Bulbs can be replaced,they are regular house hold light bulbs . Thank You,Ken

I still have the 10k bulbs that came with it, and 2 zoo med plant bulbs. I've heard that you should replace them every 6 months, and recently noticed that one of my bulbs is getting quite dim. I'm going to personally replace two at a time when they start to go out.

I use 60 watt bulbs. Should last for at least a year or longer. Bulbs can be replaced. Product works.

very low wattage, those long bulbs that are like 15-25 watts. or you could use a small hear pad on the bottom or side of the tank. OR nothing at all depending on how warm your house is!!

The bulbs are candelabra type. I have not had a problem. Excess vibration is usually the culprit to short bulb life.

Good luck getting any kind of response from the Manufacturer. I bought over 2 dozen of these units to replace 500 watt work lights in my space and after several months they began to fail. E-mails and phone calls to Lights of America never got a response. I think they are just a distribution office here in the US and are not interested in customer service.

Contact the seller or the manufacturer, they are supposed to last a lot longer than that. I did read from other reviewers that they had problems being used in enclosed light fixtures, that they burned out quickly. Mine is used in an open, recessed (can) light fixture in the ceiling. Some also tried using it for a fixture that had a dimmer switch and this is not made for that, and theirs burned out as well. I hope I helped. Mine has been in for over 5 months, hopefully I won't have to eat my words.

I have had problems with CFLs and LEDs in this lamp. They burn out quickly. I believe it has to do with the transformer in the power cord.

No! bulb has a large ballast, and reducing the electricity to the Bulb will cause it to burn out early.

Might be from dust that is getting burnt from the heat of the new bulb. Try some compressed air to blow the dust out.

I've tried these bulbs in several different fixtures, including the fixture from the company. 6 bulbs in 8 months. Last replacement bulbs, one busted. Gave up. I now use plant bulbs from Walmart that are great. Plants thrive under them. The city you live in might have a nursery that carries them. Agrolite can provide you a location. Me; I'm sticking with what I'm using now. They last! Hope this helps my friend. Also; their fixtures are weak. Ballasts burn out quick. They sent me a replacement fixture that was not shown on their ad. The " new" fixture had "shop lamp" marked on it. So I paid close to $40 for it. Same fixture at Walmart, Home Depot had same fixture for 19.99. Buyer beware!

Find one with a higher wattage equivalent, they work but not as bright as i would like.I also need to keep one of the original bulbs in the circut. (7) LED & (1) regular filament bulb.If I didn't bulbs would constantly flash. Has to do with Malibu transformer voltage regulator.

You would use very low watt, the candle type bulb. I ordered these and they were too small for my lighting fixture and I'm looking to sell them, they are brand new.

On the box it says to use only up to 75 watt when I went to petsmart. I don't know what this box says because I threw mine away. When I used 100 watt bulbs the lights blew in about 2-3 weeks every time. After I changed to 75 watts, it lasts for a lot longer.
