i bought a shit load of these https://www.menards.com/main/electrical/light-bulbs/led-light-bulbs/sylvania-48-t8-17-watt-led-daylight-fluorescents-replacement/p-1456889156784.htm i did the math on them the start up is less then a 1/4 then a t5 set up . a double light fixture for these is 10 bucks the bulbs were 4.5 some . if i bought 4 fixtures and 8 bulbs my cost is only 80 bucks ! a t5 system is 200/ 300 they sell bigger fixtures for these i like the smaller strips less wasted light . the power savings a t5 is 55 watts @ 5000 L. this bulb is 17 watts @ 2200 L so the t5 is 90.90 L per watt , the t8 led is 129.41 so it will take 18 of these bulbs to make 40000 L like a 8 bulb 8 footer set up . thats 306 watts . savings of almost a 100 watts . per set up . i have been fucking around with these bulbs for about 6 months . though now the price dropped well worth buying . its saving me about 100 bucks a month veg bill and they are very cool no heat . the t5 are hot . unless your old school and want to run every last drop of juice onto your plants thinking its going to grow faster and it wont . these t8 led rock . i know it sounds like a lot of bulbs but you do not need that many one of these to my eyes is just about as bright as a t5 sitting right next to it . i threw my spectrum meter under these surprisingly they are hitting a nice steady pattern not all chopped up like the t5 its hit and miss spectrum chart .

The most common applications for the Sylvania 17-watt 48" T8 linear 5000K LED light bulb are direct replacements for 32 watt linears with instant start ballasts. The energy-saving ultra LED lamp offers a true substitute for 32 watt fluorescent lamps. Producing a similar light output and distribution patterns as a regular bulb. Has a rated life of 36,000 hours with a high color rendering (CRI) of 82. These features makes the new LED lamp an attractive option for residential, hospitality, healthcare and retail applications. ...says the blurb

I've been using these in my T8 cab for germing/ early veg, these last 2 years

true, not as good as the original 3000 plus lux of the flouro tube

but at half the power suck I'm very happy indeed

simply: Slide of that shitty translucent cover for an instant 50% upgrade

have two as the 5000 is very red the other being cool white to balance ya grow

good luck
