@haidut ; do you still use the 130V 250W infrared bulbs at your office? Or have you found something better? Also, if you have a link to the specific bulbs, perhaps you could share with us ?
Yes I do. I have 2 x 250W red bulbs in the office and a few 500W bulbs at home. I use the 500W ones primarily in the winter after sunset and the red ones at night for a few hours in the spring/summer.
