New ceiling fans for summer (and winter)

May 20, 2011   //   by Robert Monk   //   New in electricity..., Smart Energy Blog  //  2 Comments

Summer is a’ coming and ceiling fans are a time-tested green technology that can stand-in for air conditioning at a fraction of the installed and operating costs, or significantly reduce operating cost to achieve a given ‘wind chill’ comfort level for those who have already installed A/C.

In the right finish, a ceiling fan may tie room paint and furniture together like a rug.

Have LED lamps come of age?

May 1, 2011   //   by Robert Monk   //   New in electricity..., Smart Energy Blog  //  14 Comments

Full-bright in a non-dimmed clip-lamp, these new LED lamps provide bright light. The fact that there’s a hint of glare at an oblique angle to the lamp axis is unfortunate in this installation but a great achievement in LED technology, generally. The LA/LED series lamps may turn out to be an outstanding lamp for recessed lighting applications.

Based on my 8 hours’ experience with it to date, the latest generation of LED lamps may be ‘good but not great’ (as CFL’s have been for more than two years, now). For under $10/lamp, it appears I have my hands on a 50,000-hour lamp with good domestic-use (warm) color temperature and adequate light output from a standard, 120V, A19 lamp base. The lamp claims to be dimmable but that’s a qualified ‘sort of’ based on my initial testing (see below).

This morning, I purchased (12) of a Utilitch Pro 7.5W dimmable, 3000K, 40W-equivalent LED lamp, Model number LA19DM/LED
