Ok, so about the t8s.
These fixtures are normal 4 ft shop lights, but they have all been overdriven, meaning a ballast meant to run 4 bulbs, is supplying that much power to only 2 bulbs. With standard flouro bulbs you end up having around 1.5x light output compared to a normally powered t8 bulb, while using twice the power. When I first put these together I was growing in a bureau, and they fit perfectly, so it was worth the loss of efficiency. I already owned the fixtures, just had to replace the ballasts. They worked fucking boss. I made a little scrog net for the bureau, if you kept the lamps nice and close you got a bunch of gorgeous little tight buds from it.
I grew a coupla few times in the bureau, first run was clones of nirvanas papaya, and possibly thc bomb? I worked with the guy I got the clones from, he handed me a cardboard box of clones in the work parking lot lol. After that a couple bag seed runs. Then I got “serious” and “upgraded” to 600watt in a diy tent in the closet. This set of lights got relegated to seedling duty, again, kick ass for it. I had bought a case of bulbs, and had no intention of stopping using it. Then I managed to smash like 6 or 8 u shaped t12 on a face level shelf, and after reading the procedure to clean up broken fluorescents, realizing there was bad shit in them (mercury) and not wanting to be exposed to any more , I recycled the bulbs I had left, and these started gathering dust.
Flash forward to earlier this year(post 24) when I saw these t8 led conversion lamps. I had planned to pull the leds, and make an array using the ballasts from the old t8 fixtures, enough to run 12 of these bulbs, 180 watts total. But, I assumed the the tubes would be plastic, and I could just pop the strips out easily. Wrong! The tubes are glass, and the strips are secured to the inside with a continuous, heavy bead of adhesive. I popped one to see what was inside, and that was enough to know I wasn’t doing the array like that. Breaking a bunch of glass in the basement just felt too wrong haha. And I never would have gotten all the glass shards out of the adhesive, not worth putting in a bunch of work to get slashed up. I feel the bulbs have worked pretty well, but not enough oomph that I feel comfortable flowering with them. I will say the light is really nice diffused because of the frosted glass also.
This spring my wife started getting into succulents and is already worried about putting a light over them for the winters to come, so I’m going to set at least one of these up in a little open cabinet, not unlike the bureau I used them in a bunch of years ago.
I am curious if the bulbs are any brighter, and if they draw more because of the overdriven ballast. Some day I’ll find time to open one up, wire it the “right way” and compare it to the other. I don’t want to buy anything to check the draw. Then, any my wife doesn’t take will go back to seedling duty. I have considered making an array that just holds them by the outside of the end caps and soldering the wires to the pins, I know it’ll kick ass for seedlings and young veg plants.
I realize this was more a trip down memory lane than a post about how the lights worked.
Am I the only person who feels sentimental about my old light fixtures? Can’t be, not around here anyway haha
I’d been wanting to get this all up here before, but was too lazy to type it all out. Thanks for reading if you made it this far
