Buying Guide

Match lumen output to application

Choose bulbs by lumens (e.g., ~1600 lm for 100W-equivalent CFLs) to ensure adequate brightness for rooms or task lighting

Pick the right color temperature

Select 2700K for warm/soft-white ambiance or 4100K for cooler, neutral light suited to work areas; both are common among 23W CFLs

Check base and fixture compatibility

Confirm the E26 base and T2 spiral or mini-fluorescent form factor fit your lamp or fixture before buying

Consider specialty spectral needs

For reptile enclosures and plants, opt for bulbs with appropriate UVB/UV-A output or spectra specifically labeled for those uses

Evaluate value by pack size and price-per-lumen

Multi-packs (4–8 bulbs) like common 8-packs improve cost-per-bulb; compare price per lumen to assess relative value
