EnviroGro T5 4 feet 8 tube grow light fixture is a light that is produced by Hydrofarm, Inc who has created the EnviroGro brand to offer their customers very high lumen output lights that are more energy efficient that other T5 grow lights. This light gives out 40000 lumen strong light and chews up 432 watts of electricity. It is 3 inches high, 26 inches wide and 46 inches long (7.62cm x 66.04cm x 116.84cm) and even though it is made of specular aluminum and the housing is powder coated steel it weighs only 31.4 lbs (14.24 kg). This light is made mainly for bigger indoors grow operations and because it has very low heat emission you can put these lamps just a couple of inches above your plant canopy. The color temperature of this lights bulbs is 6400K so it is best to use when plants are in their vegetative stages of their growth.
Hydrofarm 4 feet 8 tube grow light fixture is also manufactured by Hydrofarm, Inc so it is very similar to the EnviroGro T5 4 feet 8 tube grow light fixture with 40000 lumen output and 432 wattage. But the difference is in size, because this fixture is a little lighter – it weighs 28 pounds (12.7 kg). And it is also a little more low profile meaning that it is a little smaller – 46.25 inches long, 24 inches wide and 2.6 inches high (117.47cm x 60.96cm x 6.6 cm). And its housing is made with not only powder coated but also textured steel giving this light a bit different feel. It also have the low heat feature so you will be able to put your plants just a couple of inches from the bulbs and won’t burn them. And the color temperature is 6400K too, so they serve the same purpose when it comes to the time of when to use this light.
Sun Blaze T5 HO 48 is also 4 feet 8 tube grow light fixture that gives out 40000 lumens of light and chews up 432 watts of electricity per hour. But this grow light fixture is manufactured by a company called Sunlight Supply. The dimensions of this light fixture are 48 inches in length, 22.5 inches in width and 2.7 inches in height (121.92cm x 57.15cm x 6.858cm). And its weight is 31 lbs (14 kg). So in size it is somewhere between the both previously mentioned lights. But the difference is that for this light you can separately buy different color temperature bulbs. The original light fixture comes with 6500K bulbs that aren’t much different from Hydrofarms 6400K bulbs. But you can also buy 3000K bulbs that give out light that is suited for plants who are blooming. And this Sun Blaze T5 8 lamp grow light fixture also comes with 95% reflective aluminum reflector to help you reflect light back to your plants as much as possible.
LuxStar 48 grow light fixture is 4 feet 8 bulb light produced by company called LUX – Star, who is a newer firm but still produces very qualitativ lighting. Much like with the Sun Blaze T5 HO 48 fixture you have the option to choose the bulb color temperature but in this case the LUX-Star offers to buy your lights already with glow bulbs (color temperature – 6500K) or bloom bulbs (color temperature – 3000K) rather that buy the bulbs separately and then change them. This light gives out 4000 lumens and consumes 432 watt per hour. It is 47 inches long, 24 inches wide and 2.25 inches high (119.38 cm x 60.96 cm x 5.72cm) and it comes ready-made so you won’t have to spend your time on assembling them or figuring out which detail goes where.
EnviroGro FLT46 4 feet 6 tube grow light fixture is made for a little smaller indoors grow operation than the 4 feet 8 bulb one, but it is still as effective. The lumen output for this lamp is 30000 lumens and it consumes 324 watts per one hour. The features and the manufacturer of this light is basically the same as it is for the 8 bulb light but it is definitely smaller being 3 inches high, 19.5 inches width and 46 inches long (7.62cm x 49.53cm x 116.84cm) and weighing 26.3 lbs (11.9 kg).
Hydrofarm FLP46 4 feet 6 tube grow light fixture have also similar parameters as the 8 tube version does only difference being in sizing, lumen output and wattage which means that this light too is better suited for a bit smaller gardens. The lumen output for this light is 30000 lumens and wattage is 324 watts of electricity per hour. The measures of this light are 48.5 inches in length, 20.5 inches in width and 4.5 inches in height (123.19 cm x 52.07 cm x 11.43cm). And it weighs 22 pounds (9.98 kg) which weirdly enough is is quite lighter than the weight of the EnviroGro fixture.
Hydroponic LuxStar 4 feet 6 bulb light fixture gives out also 30000 lumens of light and chews up 324 watts in one hour so it is equal to other two 4 feet 6 bulb grow lights. The advantage of this light is that you have the option to either buy this light with grow bulbs whose color temperature is 6500K and who are better for plants when they are vegetating or with bloom bulbs whose color temperature is 3000K and they are better for plants when they are blooming hence the name. And the size of this light is 47 inches in length, 18.5 inches in width and 2.25 inches in height (119.38 cm x 46.99 cm x 5.72 cm) so this light is noticeably thinner that previously mentioned 6 bulb lights.

After reading all these parameters for these lights you should have some idea of how big and which size light you need. Now I will compare the prices too because let’s face it nowadays that is the biggest selling point. I will do that by calculating the amount of lumens you get for one dollar that way giving you better look at whether to splurge on the most expensive light or to save on the cheapest one.

The EnviroGro T5 4 feet 8 tube grow light fixture have 211.64 lumens per one dollar, the Hydrofarm 4 feet 8 tube grow light fixture – 174.67 lm/$, the Sun Blaze T5 HO 48 – 223.46 lumens per one dollar and the LuxStar 48 grow light fixture have on average 176.44 lumens per dollar (bloom bulbs one – 175.67 and glow bulb one – 177.21 lm/$). So looking at all these numbers we get that the best one is the Sun Blaze T5 HO 48 grow light fixture, because you will get the most lumens per each dollar you spent on the light. But of course you also need to take into consideration all the other features like size, bulb color temperature, etc. before you make your final decision.
when we look at the 4 feet bulb ones we see that the EnviroGro FLT46 4 feet 6 tube grow light fixtures lumen to dollar ratio is 178.57 , Hydrofarm FLP46 one – 169.49 and the Hydroponic LuxStar 4 feet 6 bulb light fixture has on average 161.42 lumen to dollar ratio (grow bulb one – 159.91 lm/$ and bloom bulb one – 162.92 lm/$). So between these three the best one is the EnviroGro FLT46 4 feet 6 tube grow light fixture. But the same as with the 8 bulb lamps you need to consider all the aspects of these lamps and you can’t base your decision only on the price.
And finally the Sun blaze T5 28 2 feet 8 bulb light fixture have 95.23 lumens per one dollar so this is the least of all the previously mentioned lights. But that absolutely doesn’t mean that this light is worse or lower quality than others. That just means that is is smaller and with quite different parameters. There aren’t many 2 feet 8 bulb T5 grow lights out there so if you grow shorter or smaller plants then definitely consider this light as an option.
