We break down the 3 most common sorts of T8 and T5 LED tubes used in LED lighting retrofit initiatives and their numerous professionals and cons.


Does your facility, such as a gymnasium, business or industrial constructing, have high ceilings?

Type A lamps are a very good resolution in lots of applications because of the increased skill to regulate the light by way of ballast issue. When you have just about any inquiries about where and how to utilize led neon flex (, you possibly can call us from our web-page. That is at the moment the only LED T8 lamp system that’s capable of matching a T8 system operating on a high ballast issue.

Type A lamps are a fluorescent ballast suitable lamp with exceptions. These exceptions are expansive, in actual fact nearly every manufacturer suggests consulting their record of compatibilities before putting in LED T8 tubes. Now we have discovered that there are even scenarios where the LED lamp product shouldn’t be appropriate with ballasts from the identical producer.

Additional advantages of Type A lamps are that they come in different wattages and beam angles, and lumen output for this type might be controlled by the prevailing ballast: led neon flex Low Power (LP), Normal Power (NP), and High Power (HP). Most frequently, these lamps are installed as a simple “relamp” mission, however it is crucial to think about the age of your ballasts when selecting this kind. When you intend to alter ballasts the week after you set up these LED lamps, that will undermine the goals and targets of your mission. Whether or not sort A goes to be one of the best answer to your undertaking depends significantly on your upkeep story.


Type B lamps are seeing a whole lot of modifications within the trade as a result of their many dangers.

We are still seeing points with the direct wire single-ended lamps, which require the ballast to be removed and the socket wired on to line voltage. Risks include the opportunity of lamp failure, sparks and even fires. These single-ended lamps could have been beforehand chosen to scale back upkeep time, but they pose such a large security threat that the trade is shifting in the direction of the double-ended lamp.

Double-ended Type B lamps mitigate lots of the safety issues as a result of there may be now not a manner for the electrical present to travel throughout the lampholder. This features a scenario the place you install a fluorescent lamp . You additionally not have to install an unshunted socket as a result of twin-end nature of the new lamps. Some of the main downfalls of the brand new model of these lamps are that they’re very limited in lumen output options (generally two mild ranges). That there presently are not any known lamps in the marketplace that can attain excessive output light levels required within the functions mentioned above.

Another frequent downfall of Type B LED lamps is the “flicker” factor. This is an issue that used to be prevalent with T12. Was principally eliminated by T8 options. It has now come again with the sort B tubes, however it’s not prevalent in Type A or Type C solutions. There are a few manufacturers that have come out with a flicker-free kind B resolution, but options are limited. The flicker is unnoticeable to many, but with some segments of the population it may be very debilitating (causing headaches, nausea, and so forth).


Type C’s are really the only “true LED system” among the T8 lamp options.

Type C Lamps are an LED lamp with a fixture mounted driver, with drivers now out there with three totally different commonplace outputs as well as programmable for more/less output depending on required light ranges. The kind C lamp is similar to an LED fixture in that you have a light engine and a separate driver.

Type C’s typically provide the longest life, and dimming capability that the others don’t. The rationale they’re not chosen as usually is due to their higher worth point. Total price of proudly owning a lighting system ought to be evaluated when contemplating whether or not these are your finest funding. The kind C lamp has only in the near past achieved controllability utilizing completely different Mili-amp Drivers. The drivers are costlier, but in some situations the need obtain a higher lamp life ranking 60,000 versus 50,000 hours.

Type C lamps have their advantages, however as with Type B, many of the market offerings don’t seize the excessive lumen output category. The other difficulty we’ve discovered with Type C is that virtually none of the methods are cross-suitable across manufacturers. Which means you would potentially be caught with the producer. Product line that they’ve put in in the power. You’d most definitely not be capable to find a lamp or a driver from a unique manufacturer that works with your current system down the road if that system is discontinued, or the producer goes out of enterprise, in lots of instances resulting in a completely new system investment.
