Ordered 8 of these bulbs, when they arrived one was smashed and a few others were broken internally. I was offered a credit which I used to replace the bulbs. Since then 5 of the bulbs have lasted around a day before blowing. I won't be ordering these again.
Twice now I've had these bulbs and they dont last 2 minutes before they pop! Wasnt impressed at all.
The quality and heat from the bulb is adequate for my needs. I have recently switched to ceramics for more temperature control. But I'll be keeping this for emergencies as it's good quality.
Great Bulbs , only bulbs I trust for my vivariums
Good bulbs, they last for ages and great value
