If you want to replace your T8 fluorescent lights in your home or garage with LED tube lights, you have a growing number of options. I was pointed towards the Hyperikon LED T8 tube lights by reader Pohakea (see comments) and had to give them a try myself, based on their excellent price (as low as $19) and performance specifications.
This type of LED linear lamp requires that you rewire your existing fluorescent fixture to remove the ballast: the LED lamp runs directly off of the ac mains voltage with no external ballast.
They produce a nice amount of good quality light: 2080 lm, CRI=85, 4000K. Table 1 lists the Hyperion products in 4000K and 3500K, and in comparison with a representative fluorescent T8 lamp.

Instant-on: not so much
However, they do have a problem: although their product description specifically says they are “Instant On”, there is a noticeable delay from turn-on until you see the light. This may not seem like a big deal, but after having lived for several years with the much-shorter turn-on delay in one of the early Philips L-Prize bulbs, I can tell you that every dang time I turn that bulb on, I notice it, and it’s made me sensitive to how irritating a turn-on delay can be.
See the delay for yourself in this video:
For me, that delay is a deal-breaker compared to LED lights with true instant-on. However, if you have this in a room where the lights are not used much, or if you simply like the inexpensive price, these lights could be for you. And, the Hypericon’s short delay is much preferable when compared to the flicker/flash you get from fluorescent lights when they attempt to start up in a cold garage.
You can get them singly for $18, the lowest price of any LED T8 lamp I’ve tested. The ones I tested were frosted and had no pixelation. If you have them behind a diffuser panel on your fixture, you might want the clear version.
