They make T5 compatible LED lights . They use a bit less energy but I am not sure how much less. I haven’t used the T5 LED’s so I am not a good person to ask about that. T5’s are not as efficient as LED’s but give off very little heat. The cost vs efficiency vs heat vs lifetime vs intensity vs etc is all debatable. I bought the fixtures about 13 years ago when I started growing inside because I was trying to go cheapo. They worked well for me then and I still like the T5’s to veg better but my LED’s are blurple. I don’t like blurple.
