T5 lights are some of the best grow lights out there, because they offer great energy efficiency and great brightness, while being relatively cheap and compact in size. That’s why it is smart to buy T5 HO fixtures for you indoors garden, but if you decide to do that, then you will definitely also need great replacement bulbs, because the bulbs are the part of T5 fixture that provide the light that shines on your plants. I recommend buying these ViaVolt T5 bulbs as replacement bulbs for your 4 feet T5 HO fixture, because not only they are very cost effective, but also very powerful.
The watt amount that each one of these T5 bulbs will consume is 54 watts, and each bulbs will in return give out 5,000 lumens worth of light. This ranks up to lumen to watt ratio of 92.5 meaning that the light will emit 92 lumens per each watt that is consumes.
These bulbs are meant for indoors application so they work best in good conditions. But the great thing about these bulb is that, because they are meant for indoors use they are specially designed not to emit a lot of heat that can quickly spike the temperature in a smaller indoors grow room and hurt the plants. So with these bulbs you won’t have any problems, only better and more efficient lights to use on your plants.
On average these bulbs will last up to even 20,000 hours which means that once you replace your previous bulbs with these ones you won’t have to change them for quite some time – even if you run them on a 24/7 life cycle 365 days a year they will last you more than 2 years.
The color temperature of these ViaVolt bulbs is 6,500 Kelvins, but in light color standards the light emitted by these bulbs is cool white. This means that they have similar color temperature of the light we get in the summer during the day. This makes them great for plants that are in their growing or vegetating stages of the growth.
Size and compatibility
The bulb itself is 0.625 inches in its diameter, because the bulb is a T5 bulb and it is about 48 inches or 4 feet long, so it will be compatible with any T5 fixture that is a High Output (HO) fixture, in length is 4 feet or 48 inches long and have Bi-Pin type of light bulb base. Just be sure, that your T5 fixture is not a Very High Output (VHO) one, because in this case these bulbs won’t be compatible to them.
