F30T12 Colortone 50 Fluorescent Light Bulbs

Price Each: $29.12
Item Number: BLF10471
F30T12 Colortone 50 fluorescent light bulbs are a suitable replacement for any T12 lamp with poor color properties. Most people find it's easier to work and function under the natural lighting effect of full spectrum lights. These will work anywhere you might use a standard 36 inch T12 lamp. Simply replace it to get better color, visual enhancement and a cleaner, brighter appearance to your home or office. These are great anywhere people work on computer screens, it should help reduce eyestrain. The Philips Colortone 50 is one of those special light bulbs that have been used for color corrected lighting for many years. And because it is the T12 version, it still operates on magnetic ballasts typically. The phosphor inside gives off light at a 92 color rendering index. That means on a hypothetical scale of 100 CRI, this is very close to perfectly color accurate. You'll often see this used in industrial situations were color matching is important such as the printing industry, color proofing, retail and the dental industry. With this type of light you can actually determine slight variances of color and shading which is very important for all of these different occupations. The color temperature is 5000K which is very close to noon time daylight and produces light the way our eyes best use it. This is very good as a reading light as well as being good for color rendering. It's been used for many decades and continues to be into the future. We also have this in the T8 version if you need that, that's the one that operates on an electronic ballast. If you're unsure of which one you have or what you can do with this lamp, you can always give us a call or email and we can help you with that. We have a lot of experience with this type of lighting and we often know what's best for your situation if you can just give us a little bit of extra information. This is an excellent way to get good lighting for almost any situation you have, it doesn't have to be these particular industries or anything like that.

General information.
At, we want to provide you with the highest quality F30T12 fluorescent bulbs that are going to last for a long time and take care of your lighting replacement needs. The 30-watt T12 fluorescent tubes are the older style of fluorescents that were used for general lighting and still are today in many light fixtures. Although many have been replaced with F25T8 and lower watt LED, there’s still a lot of you who have these and need these for a fluorescent replacement bulb. Most of the time this fluorescent light bulb cool white was the most popular for offices and commercial lighting everywhere. It has a long life of 20,000 hours average life. Now we have these as a consumable item that you can still buy or consider replacing something more energy-efficient. The life hours would increase if you keep the lamps/bulbs on and never shut them off.

The operation of F30T12 lamps.
These lamps operate on a magnetic ballast most of the time, although on a few occasions people and converted some of their light fixtures to an electronic ballast that will utilize this light. It’s tough to get any more light fixtures that are made for this type of bulb, but we still have a few of those. Most people are converted to the T8’s that operate on an electronic ballast, and that’s been the natural replacement for the old light bulb cool white 4100K. The ballast in this operation is much more massive than the electronic ballasts because of all the copper windings on the inside. It’s also a rapid start ballast and starting operation, not an instant start. Sometimes you’ll see this a little slow to light, or it’ll flicker a little bit before it goes entirely on. That was the nature of this type of lamp, and that’s why a lot of people are replacing it because of its flickering, poor color rendering index and poor energy consumption. But for many people, it might not be in the budget to replace them all at this time for something more efficient and if that’s the case we have plenty in stock for you.

The colors for F30T12.
There’s no talking about F30T12 light bulbs without talking about color temperature. These come in three primary colors although there are many others in smaller variations. The most common are cool white, warm white and daylight. All of these have adequate light output and are probably some of the lowest cost types of T12 bulbs that you can get today. There are other light colors such as the more particular Kelvin temperature versions which are also available. Not only are these colors available, but the more color correct type of fluorescents are still used in many kinds of applications, and that includes the Chroma 50 and Chroma 75 for people who need a daylight color that has a high color rendering. Once again, for people that are moving into something more energy-efficient we do have T8 lamps with the same color properties and improvements. Typically, you won’t find them in your local store anymore, but we have them ready for shipping every day.

Save money and update your lighting.
With the advent of more energy-efficient light sources such as LED tube lights, you see some of these replaced now with T8 LED tubes. It’s a good choice if you want to save more energy and possibly qualify for some different rebate programs that electrical utilities have. LED lights will give you the same amount of light for less wattage and so this is where you’ll get the best possible savings. Some people don’t just change the tubes, they will go for a whole new light fixture if some of the incentives are good or their lighting system is particularly old. If that’s the case we have a complete line of lighting fixtures in LED and for some situations with the payback being so good, it might make sense to go to an entirely new fixture instead of just retrofitting to an LED bulb. If you want to know how much you’ll save on going to an LED T8 light bulb, we have a free download on the left-hand column of our website that is an energy savings calculator in an Excel spreadsheet format. It will give you all the information that you need to make a simple comparison for what you have now and what you may be thinking about going to as far as in more efficient lighting solution.

Troubleshooting these lamps.
If you’re having problems getting these to light up properly, there may be a couple of different things you want to consider. Of course, it could just be that you need new light bulbs, but it could be something else like the ballast. The old magnetic ballast that these operate on word always the greatest at voltage regulation in lamp operation. If the lamp seems to be flickering when it’s trying to start, it could be a lamp, but it’s most likely the ballast just getting old and not able to supply the proper voltage to start it up. Also if you see some and blackening, which often occurs very quickly over a short period, you could assume that the ballast is overvoltage in the lamp and it's pushing it to an early grave. In either of these cases, you need to change the ballast, and you won’t be able to get magnetic ballast anymore, but we do have electronic ballasts for these if you need them. Even though these are just a three-foot version, this in proper starting or problem seems to be pervasive with this type of lamp on occasion. This is when you may want to consider going to at least a T8 fluorescent. The reason for that is that you would have to replace the ballast anyway, so you can probably get a T8 ballast with an F25T8 lamp to do the replacement, and you probably need to do just a minor rewire on one of the sockets in the light fixture itself. And if you’re doing all that to the light fixture, might we suggest going one step further, replacing the entire fixture. With all the different low-cost choices in new light fixtures with the latest LED lighting, wouldn’t it make sense to maybe replaced the whole thing because the ones you have are probably quite old to start with? You will probably eliminate a lot of the frustration you have with an older light fixture by just making the replacement at an opportune time.
