*by B***. on May 6, 2025*

Good price for 2 bulbs it's hard to find this style socket works well came fast and intact and my ballast has wattage dimming in which the bulb seems to be able to handle just fine I haven't had the bulb very long so I can't really say how long it lasts and set to the full 315 wattage it's like the sun is in my basement super bright

### ⭐ Horrible product
*by B***N on October 7, 2025*

It's very simple for this product, it's GARBAGE. The lifespan of this product is not worth selling mine lasted barely 6 months. And from what I'm understanding that is lucky because many bulbs burn out within one day. This product should be taken off the shelf in every person that has purchased and should get a return or a refund.
