The end of the bulb become blackish at the beginning and become black. The bulb still illuminate at center portion but not enough to illuminate to see things or read letters.

I have an old hood on my aquarium, and bought one of these bulbs to replace one that had fizzled out. The bulb did burn with a rather dim purpley-blue cast for the first 12 hours or so. Then it suddenly brightened, and has been beautiful since. Some fluorescent bulbs have a "burn in" period, and I guess this is one of them. It is best to leave the lights on for at least 12 hours the first time, apparently. Try leaving your light on for longer than normal for a couple of days and see if it comes round to it's true light. If you are still dim after a couple of days, I'd look into getting a new starter for your hood. I have an old hood on my aquarium, and bought one of these bulbs to replace one that had fizzled out.

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

All you have to do is clean and replace the bulb. To clean just wipe off with a damp cloth. Plug in and try using it. I would order a new bulb to be sure it is working at peak performance.

I did not have a burning smell after installing the new lamp. I like the recommendation from Julie Jo about calling Philips and asking them is a burning smell is to be expected. When I replaced my lamp I carefully vacuumed out the "cave" where the lamp is inserted (meaning that I did not touch the glass plate that the light is projected into) with a vacuum corner attachment; and also vacuumed the cage fan that cools the lamp.And very importantly I made sure I did not touch any part of the glass lamp with my fingers, which always have slight body oil - which might be the source of the burning smell.

First check to see if the dimmer is turned on. It is possible that the bulb you bought is broke. Try another one first. Thanks

Mine has lasted 2 years now. When you installed it you did not touch the lamp at all with your fingers and transfer anything to the lamp face? That maybe could create a hot spot and it burned out? Sometimes there is just a defect. When I first installed it I must have jarred the optical block so I had a rose tint across the top of the screen about 3 inches down. After a while you learn to ignore it, but I noticed recently that the line is gone. I moved the set a bit recently to get at a side connector and I am wondering whether that jarred something back in place. Now I won't move the set at all until the bulb dies again or something else goes south.

Tammy, I'm afraid my bulb was defective when received and had to be returned. I believe some others have described some of the things which you are now seeing. Check all of the reviews. Good luck.

Mary - we haven't had that issue at all with our unit. I would test it in a different wall socket and see if the issue repeats itself. If so, I would replace the bulb and, if your lamp strobes again, I think you have sufficient evidence to point to a flaw in the device. Best of luck. Hope you get it going well enough - my wife is delighted with ours. Joe

Check bulb or contacts maybe dirty. Dirty was my problem since I work in the oilfield.

No. Special bulb I think it is an LED. It should never burn out if it is an LED

i replaced mine and didn't have any issues (smell) . Is it still smelling? You may have a more serious problem. I would remove the newly installed bulb assemble, inspect, and start again.

Make sure the socket has power and that the cord is properly plugged in, try a another one if you have one, the size is pretty generic. But yes, either the unit is dead or it isn't getting power. In the off chance the bulbs have gone out you can see if it's charged by using the power meter.

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 occasionally get a bulb that is damaged or doesn't work. I test them on a lamp before use. One bulb I had to turn the switch twice.
